Software renewal scammers unmasked

We’ve been tracking a fraudulent scheme involving renewal notifications for several months now. It came to our attention because the Malwarebytes brand as well as other popular names were being used to send fake invoices via email.

The concept is simple but effective. You receive an invoice for a product you may or may not have used in the past for an usually high amount. Feeling upset or annoyed you call the phone number provided to dispute the charge and ask for your money back.

That was your first mistake. The second is letting strangers access your computer remotely for them to uninstall the product in order to avoid the charge. Before you know it your computer is locked and displaying random popups.

In this blog, we follow the trail from victim to scammer and identify one group running this shady business practice.

Fake renewal notifications

We’ve received a number of similar reports from people that have been scammed or simply wanted to alert us. It starts from an email using branding from a number of security companies, although in this blog we will focus on those that impersonate Malwarebytes.

The email includes an invoice renewal for the product stating that it has already been processed via credit card. The amount usually is in the $300 to $500 range, which is a lot more than what we normally charge.

  • scam email
  • scam email0
  • scam email2

The scammers are hoping victims will call them to dispute the automatic renewal. In the heat of the moment, most people would not think to check their bank or credit card statement instead.

This scheme is essentially a lead generation mechanism, just like what we see with fake browser alerts (browlocks). It just happens to use a different delivery vector (email) and is perhaps just as, if not more effective.

Remote access and sales pitch

Victims are instructed to visit a website to give the ‘technician’ access to their computer. The reason given is that the service needs to be uninstalled first before a refund can be granted.

In this instance, the scammers asked us to visit zfix[.]tech, a website linking to a number of remote access programs. They asked us to download TeamViewer and share the ID and password so they could connect.

They also quietly downloaded and installed another program (SupRemo) to maintain unattended access. This means that even if you shutdown TeamViewer, the scammers can still connect to your computer when they feel like it.

The next part of the scheme is interesting because it shows how the fraudsters are able to extort money from their victims. Since the renewal email is fake they have to find a way to trick you into paying them even if you refuse to.

The scammers take to their favorite tool, notepad, to start typing away about the risks of not renewing the service. They particularly insist on the fact that the computer may not work anymore if they proceed.

Locking up the machine

Scammers have been known to lock victims’ machines on numerous occasions. They typically use the SysKey Windows utility to put a password that only they know.

In this case, they used a different technique. Working behind the scenes, they downloaded a VBS script onto the machine which they placed into the Startup folder.

script

The Startup folder location is a loading point that can be abused easily because it can trigger code to run when the system loads Windows. Unsurprisingly, before parting ways, the scammers asked us to restart the machine to complete the uninstallation process.

lock

After a restart, we see an alert dialog about the Windows license being out of date. This message keeps on showing despite clicking the OK button and also starts to open a number of browser windows to mimic some kind of malware infection.

At this point, you might be tempted to call the number for help but this would end in paying hundreds of dollars to fraudsters. There is a way to restore your computer safely which we cover in the next section.

Disabling the locking script

The first thing to do is disconnect your machine from the Internet. If it’s using a wired cord to the modem unplug it, otherwise simply turn off the modem or your WiFi access point.

Then proceed to disable the script:

  • Ctrl+Alt+Delete
  • Select Task Manager
  • Select Microsoft Windows Based Script Host
  • Click ‘End task’
closescript

Then delete the script:

  • Click ‘More details’ (if needed) in Task Manager
  • Choose ‘Run new task’
  • Type explorer in the box

Your Desktop will be visible again, allowing you to browse to:

C:Users[your username]AppDataRoamingMicrosoftWindowsStart MenuProgramsStartup

From there, delete the WIN LICENSE.vbs file

Identifying the scammers

We don’t always get too many details from scammers that could help us to identify who they are, but sometimes with luck, skill and tools like HYAS Insight we can shed light on adversary infrastructure. Here the scammers left a few trails with the VBS script but more importantly the first website we visited to download remote access software.

We were able to identify the registrant behind the zfix[.]tech domain as being Aman Deep Singh Sethi using the aman.techsquadonline@gmail[.]com email address. Pivoting on the associated phone number [+9]19810996265 we uncovered a larger piece of their scamming infrastructure as well as an associate named Swinder Singh.

Both individuals are registered as directors of a company in New Delhi called Lucro Soft pvt located at 14/28, F/F SUBHASH NAGAR NEW DELHI West Delhi DL 110027.

company

Although this company was incorporated in 2018, the scammers have been active since at least 2015 and used several different domain names and identities. We are blocking this infrastructure and reporting it for takedown as well. If you would like more information about this group, please get in touch with us.

An active scheme

This particular scheme has been very active for the past few months and it is difficult to estimate how many people fell victim to it.

Tech support scams have been around for many years and continue to be a huge problem in part because of the lack of action on the field where they are known to take place.

However, there is also a strong community out there that is pursuing scammers and giving back to victims. The likes of Jim Browning who made headlines for his hacking into the CCTV of a call centre are doing a tireless job. For this investigation, we used a Virtual Machine that was made by @NeeP that mimics a normal user desktop.

The human impact of a Royal Mail phishing scam

Last week, we looked at a Royal Mail themed scam which has very quickly become the weapon of choice for phishers. It’s pretty much everywhere at this point. Even one of my relatives with a semi-mystical ability to never experience a scam ever, received a fake SMS at the weekend.

The problem with common attacks is we grow complacent, or assume it isn’t really a big deal. Sadly, they’re always going to be a problem for someone. It doesn’t matter how tech-savvy you are, nothing is bulletproof. Anybody, including myself, can be caught out by a momentary lapse in concentration.

People who lose out to internet fakery often feel guilty, or assume that they messed up somehow. Nobody wants to be laughed at via internet shenanigans. I’d like to think most folks are sympathetic when people are brave enough to speak out.

“Surely people don’t fall for these things” is a well worn refrain. Sadly they do, and one such person spelt out the awful cost last Sunday. They had indeed received a bogus Royal Mail text, and entered their payment details into the phishing page. How bad could things get?

We’re about to find out.

Things have gotten: very bad

The victim was asked for a bogus £2.99 postage fee last Friday, having not seen the scam warnings circulating online. Below is an example of the scam that Malwarebytes Labs received:

IMG 4808
The text of the Royal Mail scam

Royal Mail: Your package Has A £2.99 shipping Fee, to pay this now please visit www[dot]royalmail-shippingupdate[dot]com. Your package will be returned if fee is unpaid

In our last post about it, we pointed out that these scams work because with so much online ordering going on during this cardboard-laden pandemic, people aren’t 100% sure what’s due to arrive. And that means speculative messages about fake parcels have a good chance of success.

A similar thing happened here. If the target wasn’t due a birthday, the scam may not have worked on them. But the message will have gone to lots of people, and one of them, perhaps many, will have been expecting a delivery. As it was, they were expecting “a couple of packages” and so “thought nothing else of it”.

This is absolutely the key moment where the battle was already lost.

The scam asks recipients to pay a £2.99 GBP fee, but of course the scammers are after much more. To pay the fee, the victim has to enter their personal details, and credit card details.

Scammers get to work

The victim’s bank accounts were compromised very quickly, and the phishers wasting no time at all in going for gold. A day or so after they paid the bogus fee, the bank contacted the victim to let them know what had gone wrong. As it turns out, quite a lot:

  • Multiple direct debits (recurring billing) for mobile phone companies and technology stores
  • Transactions of £300 for the Argos store
  • Debit cards for banking cancelled, with new ones issued as replacements
  • Brand new sort code / account numbers for her bank account, as those had been given to the phishers too

This is really bad news for the victim, and a massive inconvenience. Don’t forget the pandemic impact here, either. At a time when the ideal option is cashless / card payments only, this person now has no cards and no easy way to withdraw money either.

If this had been where it ended, that would be bad enough. However, things were sadly about to get worse.

Phished by phone

The bank phoned the victim asking them to transfer their money into their “replacement” account. I’m sure you can already see where this is going wrong. No bank is going to cold call a scam victim, and also ask them to start transferring money. Why can’t the bank do it?

The answer, unfortunately, is that the bank can do it. This cold caller was a scammer armed with details gathered from the scam page a day or so prior. The follow up strike gave the individual, who was already reeling from rapidly losing lots of money, no time to regain some balance or get their game face on. If this call had come a week or so after the initial phish, the next few paragraphs would possibly look quite different.

From bad to worse

Good news: the victim asked the person on the call to verify their bank credentials. Bad news: they forgot the phisher already had access to everything in their account. As a result, they listed account balances and other information to keep everything nice and convincing.

Two smaller transactions were sent to the “new” account, at which point the victim realised they were being scammed all over again. Every penny they had to their name was gone.

Having wool pulled over your eyes once is bad enough. To then hand over cash to the scammers by telephone is the icing on a very bitter cake. So-called safe account scams are quite the pain, and this is what caught them out second time around.

A simple phish, a massive problem

There is no real happy ending to this tale currently, outside some reassurance the victim will probably get most or all of their money back. Consider that this person’s nightmare scenario began with a simple, believable, SMS message claiming a package was being held.

A few keystrokes, some brief personal information entered on a phishing site with Royal Mail branding, and they’ve been plunged into a situation which could take weeks or more to resolve. All that stress, in the middle of the never-ending pandemic. It’s an awful story, and a chilling insight into how much is at stake every single time a throwaway phish lands in your mailbox or SMS tray.

We wish Emmeline all the best in recovering her money and commend her for her courage in coming forward and showing the true cost of these scams.

When contractors attack: two years in jail for vengeful IT admin

An IT contractor working for an IT consultancy company took it upon himself to perform an act of revenge against the firm he worked at, after they complained about his performance. The charge he faced was breaking into the network of a company in Carlsbad, California. And it got him two years in prison.

What happened?

Deepanshu Kher was helping a client to transition to a Microsoft Office 365 environment. But apparently the client company was so displeased with Kher’s performance that they complained about it to the consultancy company that despatched him. As a consequence, Kher got laid off and went back to India.

Some two months later, once he was outside of the US, Kher decided to infiltrate the California firm’s servers and deleted over 80% of employee Microsoft Office 365 accounts.

The aftermath

As employees were suddenly unable to access emails, contacts, calendars, stored documents, as well as Microsoft’s Virtual Teams remote management platform, they were unable to do their jobs. It took the company two days to get back in full swing. But all kinds of IT-related issues persisted for three more months after the cyberattack.

The arrest

The company informed the FBI about the incident and it wasn’t all that hard to figure out who the culprit was. Unaware of the outstanding warrant for his arrest, Kher was arrested while flying from India to the US. US District Court Judge Marilyn Huff charged Kher with intentional damage to a protected computer, a crime which can lead to up to 10 years in prison and a $250,000 fine.

Insider threat

The CERT Definition of an insider threat is:

 “Insider Threat – the potential for an individual who has or had authorized access to an organization’s assets to use their access, either maliciously or unintentionally, to act in a way that could negatively affect the organization.”

Kher did have credentialed access to the network and the Office 365 environment as part of his job, and he certainly acted in a way that negatively affected the company. So we see this as an insider threat, even though he was no longer working for the victim.

Controlling insider incidents

While cybersecurity education and awareness are initiatives that every organization must invest in, there are times when these are simply not enough. Such initiatives may decrease the likelihood of accidental insider incidents, but not for negligence-based incidents, professional insiders, or other sophisticated attack campaigns. Organizations must implement controls and use software to minimize insider threat incidents.

The controls

Controls keep an organization’s system, network, and assets safe. They also minimize the risk of insider threats. Below are some controls organizations may want to consider adopting:

  • Block harmful activity. This includes preventing access to particular websites, or stopping employees from downloading and installing certain programs.
  • “Allow list” applications so that everything is blocked until and unless it is specifically allowed. This includes the file types of email attachments employees can open.
  • Use the principle of least privilege and give employee accounts the access they need, and nothing more.
  • Apply the same principle to data access, so data is only available to people whose job requires it—organizations should focus on this, too, when it comes to their telework or remote workers.
  • Put flags on old credentials. Former employees may attempt to use the credentials they used when they were still employed.
  • Create an employee termination process.

The last two points in particular could have helped prevent this incident. Both the consultancy company, and the victim, could have looked at this, or taken steps when they realised that Kher was unhappy about being laid off. But often when two entities are supposed to do something, they expect the other to do it. With the end result that neither did.

Worst case scenario

This was not a worst-case scenario. The contractor had access to one specific, albeit vital, part of the organization. I’m sure you can imagine someone in your organization that can do a lot more harm than that if they wanted to. Remember that when your roads part in the future. If they no longer work for you, they should not have access to your network.

Stay safe, everyone!

Report goes “behind enemy lines” to reveal SilverFish cyber-espionage group

The PRODAFT Threat Intelligence Team has published a report (pdf) that gives an unusually clear look at the size and structure of organized cybercrime.

It uncovered a global cybercrime campaign that uses modern management methods, sophisticated tools—including its own malware testing sandbox—and has strong ties with the SolarWinds attack, the EvilCorp group, and some other well-known malware campaigns.

SilverFish uncovered

The research team managed to do a full investigation of one of the SilverFish group’s Command and Control (C2) servers, after detecting an online domain (databasegalore[.]com) from previously published Identifiers of Compromise (IOCs).

It was possible for researchers to create a unique fingerprint of one of the online servers by using multiple metrics, such as installed software. After 12 hours of global scans of the IP4 range, they identified more than 200 other hosts with a very similar setup.

According to the report this “enabled the PTI Team to access the management infrastructure” of the group and learn significant information about how the group worked, who it had attacked, and how.

Sophisticated organization

What the researchers found was a highly sophisticated group of cybercriminals targeting large corporations and public institutions worldwide, with a focus on the EU and the US. They named this organization the SilverFish group.

By linking together the C2 servers they found, and comparing them to known IOCs, the researchers were able to connect the SilverFish group to the infamous SolarWinds attacks.

A large subset of the servers the researchers identified were also used by the infamous EvilCorp group, which modified the TrickBot infrastructure for the purpose of a large-scale cyber espionage campaign.

Links to SolarWinds

The report describes a “significant overlap” between the 4,700 victims identified during the investigation and organizations affected by the SolarWinds attacks. A significant part of the large infrastructure was found to have strong connections with the SolarWinds IOCs shared by three different security companies. The conclusion being that these servers most likely took part in the SolarWinds campaign.

Links to Trickbot

By looking at the group’s tactics, techniques, and procedures (TTP), combined with the technical complexity of the SilverFish group’s attacks, PRODAFT was able to detect similar findings in the c2 server, command statistics, infection dates, targeted sectors and countries, tools used during the attacks, executed commands, and other information that was very similar to those used by TrickBot.

So, is this group related with TrickBot? Not likely, but the research shows that the SilverFish group is using a similar version of the TrickBot infrastructure and codebase. It also found evidence of WastedLocker malware and other TTPs that matched with both EvilCorp and SolarWinds.

Links to EvilCorp

EvilCorp is the name of a vast, international cybercrime network. The alleged leaders of this network are very high on the FBI’s wanted list. In 2019, US authorities filed charges against EvilCorp’s alleged leaders, Maksim Yakubets and Igor Turashev, accusing them of using malware to steal millions of dollars from groups, including schools and religious organizations, in over 40 countries. EvilCorp is held responsible for the development and distribution of the Dridex and WastedLocker malware.

Malwarebytes’ Threat Intel Team commented:

Prodaft also mentions ties with the WastedLocker ransomware thought to be operated by EvilCorp, likely from the Traffic Distribution System analysis. One of the hostnames in particular is related to the SocGholish social engineering toolkit and is used to fingerprint victims before distribution of the final payload.

Management

According to PRODAFT, the main dashboard of the SilverFish C2 control panel features a section named “Active Teams”. SilverFish uses a team-based workflow model and a triage system similar to modern project management applications. Each user can write comments about each victim. Based on these (mainly Russian) comments, the researchers gained a better understanding of the motivation of the group and the prioritization of the victims—operations were prioritized based on these comments.

A hierarchy was also found to be present in the comments on the C2 server, enabling management of different targets, assignment of these targets to different groups and triage of incoming victims.

Targets

The main areas of focus for the SilverFish group appear to be the US and Europe, with each region serviced by different teams. They also seem to primarily target critical infrastructure. Successfully compromised victims were found in nearly all critical infrastructures (as defined in the NIST Cyber Security Framework).

The SilverFish group predominantly targets critical entities like energy, defense, and government or Fortune 500 enterprises. Second, the researchers found comments in the C2 servers that indicate ignoring victims like universities, small companies, and other systems which they consider worthless.

Approximately half of the victims were found to be corporations which have a market value of more than $100 million USD, as per their public financial statements.

WordPress

In contrast to traditional attacks that use a domain name purchased via means of anonymous payments, SilverFish is using hacked domains for redirecting traffic to their C2 control panel.

To avoid disrupting the legitimate traffic of the hacked website, the SilverFish group creates new subdomains, which makes it almost impossible for a website owner to understand that their domain is being exploited in an attack. The frequency in which they change domains would imply that the SilverFish group has more than 1,000 already compromised websites, which are rotated almost every other day.

A significant number of these compromised websites were using WordPress. The report notes that while it is possible to buy login credentials from underground markets, “the amount of compromised websites with the same software shows us that the SilverFish group might also be leveraging 0-day or N-day exploits.” WordPress is, by far, the world’s most commonly used web Content Management System, and out-of-date installations and vulnerable plugins provide no shortage of targets.

Post-exploitation

Perhaps unsurprisingly, the SilverFish group was found to make extensive use of publicly available “red teaming” tools such as Empire, Cobalt Strike and Mimikatz, as well as Powershell, BAT, CSPROJ, JavaScript and HTA files used for enumeration and data exfiltration.

Executed Cobalt Strike beacons use domain fronting for communicating to the C2 server. Domain fronting obscures the eventual destination of HTTP traffic by relaying it from the server listed in the publicly-readable SNI portion of a request, to a different server listed in the private (encrypted) Host header.

The main goals of the SilverFish group are likely to be covert reconnaissance and data exfiltration. According to PRODAFT, the commands and scripts the SilverFish group use “strongly indicates sophistication and an advanced post-exploitation skillset”.

Remote sandboxing

The most astounding find the researchers uncovered was that the SilverFish group has designed an unprecedented malware detection sandbox, formed by actual enterprise victims, which enables the adversaries to test their malicious payloads on live systems with different enterprise AV and EDR solutions (enterprise systems can be hard for criminals to acquire).

Malwarebytes Threat Intel Team commented:

Machines are profiled and used as a testing ground, a sort of live antivirus testing platform featuring many different EDR products.

The SilverFish attackers were using this system to periodically test their malicious payloads on more than 6,000 victim devices, scripts, and implants. According to the report, the SilverFish group members appear to be tracking the detection rate of their payloads in real time.

Level of sophistication

PRODAFT says “we believe this case to be an important cornerstone in terms of understanding capabilities of organized threat actors”, and it is hard to disagree.

Although ransomware groups can be well organised, they are mostly engaged in noisy smash-and-grab raids. The SilverFish group is something different. According to PRODAFT it is an “organization that operates in an organized and disciplined manner in a hierarchical environment, one that is even highly compartmentalized,” that takes a “structured approach to covert cyber-espionage.”

Attribution

The Prodaft researchers refrain from attribution, but there are some strong pointers which can be found in their extensive report.

  • Russian comments and use of Russian slang words on the C2 servers.
  • Indications that the group is sparing countries that were part of the former USSR and still have strong ties with Russia.
  • The group is active during European work hours, with most of its activity recorded between 08:00 and 20:00 (UTC).
  • The attention to critical infrastructure, and major companies in the US and Europe.

Attribution is hard and sometimes the conclusion you come to is the one the threat-actors want you to reach. But if it walks like a duck and quacks like a duck….

How to enable Facebook’s hardware key authentication for iOS and Android

Since 2017 desktop users have had the opportunity to use physical security keys to log in to their Facebook accounts. Now iOS and Android users have the same option too. Physical security keys are a more secure option for two-factor authentication (2FA) than SMS (which is vulnerable to SIM swap attacks and phishing), and apps that generate codes or push notifications (which are also vulnerable to phishing).

Two-factor authentication (2FA)

2FA is the least complex version of multi-factor authorization (MFA) and was invented to add an extra layer of security to the—now considered old-fashioned and insecure—simple login procedure of using a username and password. By definition, 2FA depends on two different methods of identifying a user.

Authentication factors are commonly divided into three groups:

  • Something you know, such as a password.
  • Something you have, such as a code sent by SMS, or a hardware key.
  • Something you are, such as your face or fingerprints.

Different 2FA schemes typically rely on users providing a password and one of the other factors. If you are an Android or iOS user, Facebook will now let you authenticate yourself with a password (something you know) and a hardware security key (something you have).

Hardware security keys

Hardware keys, also known as physical security keys, connect to your device via USB-A, USB-C, Lightning, NFC, or Bluetooth, and are portable enough to be carried on a keychain.

Most of them use an open authentication standard, called FIDO U2F. U2F enables internet users to securely access any number of online services with one single security key, with no drivers or client software needed. 

FIDO2 is the latest generation of the U2F protocol and it allows devices other than hardware keys, such as fingerprint sensors or laptops and phones with face recognition, to act as hardware keys.

How do security keys work?

You can use a hardware security key for as many accounts as you like. Once the key has been set up to work with a service, logging in is as simple as inserting the security key into your device (or wirelessly connecting it) and pressing a button on the key itself.

Behind the scenes, the security key is presented with a challenge by your web browser or app. It then cryptographically signs the challenge, verifying your identity.

Setting up Facebook for physical security keys

To add a physical security key as a 2FA factor for Facebook, open Facebook on your device and open the menu.

In the Menu click on Settings under Settings and Privacy.

Settings

You will see the Account Settings menu. Click on Security and Login under Security.

security and login

You will see the Security and Login menu. Click on Use two-factor authentication under Two-Factor Authentication.

Two-Factor Authentication

In the Two-Factor Authentication menu select the Security Key option and click on Continue.

security keys

From there, follow the instructions that are device and key-specific to add your security key as an extra factor of authentication.

Privacy and security

Imagine all the information an attacker might find out about you if they should get hold of your Facebook credentials. It’s not just all your public, and private posts, but your Messenger conversations as well. The first thing a successful attacker will do is enable 2FA to lock you out. So get ahead in the game and enable it yourself. Any 2FA is better than none, but a security key is the most secure form of 2FA.

2FA enabled

Stay safe, everyone!

Safe Connections Act could help domestic abuse survivors take control of their digital lives

A bill introduced in the US Senate could help domestic abuse and sex trafficking survivors—including those tracked by stalkerware-type applications—regain digital independence through swift, shared phone plan termination and the extension of mobile phone plan subsidies.

Titled the Safe Connections Act, the bill targets the significant problem of shared mobile phone contracts between abuse survivors and their abusers. For survivors in these situations, a shared mobile phone plan could reveal who the survivor has called and when. Shared mobile phone plans also complicate matters for survivors who hope to physically escape their abusers, as abusers could report phones owned in their name as stolen, weaponizing law enforcement to locate a survivor.

Democratic US Senator Brian Schatz, who is one of the sponsors of the bill, said that he hopes the Safe Connections Act will give control back to survivors.

“Giving domestic violence abusers control over their victims’ cell phones is a terrifying reality for many survivors,” Schatz said in a press release. “Right now there is no easy way out for these victims – they’re trapped in by contracts and hefty fees. Our bill helps survivors get out of these shared plans and tries to find more ways to help victims stay connected with their families and support networks.”

Importantly, the bill would also extend easier access to government-subsidized mobile phone programs, which means that survivors being tracked through stalkerware-type applications could more easily toss their compromised device and start anew.

What does the Safe Connections Act do?

The Safe Connections Act—which you can read in full here—was introduced earlier this year by a bipartisan slate of US Senators, including Sens. Schatz of Hawaii, Deb Fischer of Nebraska, Richard Blumenthal of Connecticut, Rick Scott of Florida, and Jacky Rosen of Nevada.

The bill has three core components to aid “survivors,” which the bill defines as anyone over the age of 18 who has suffered from domestic violence, dating violence, sexual assault, stalking, or sex trafficking.

First, if passed, the bill would place new requirements on mobile service providers—such as Verizon, AT&T, T-Mobile, and Mint Mobile—to more rapidly help survivors who request to remove either themselves or an abuser from a shared phone plan, whether the survivor is the primary account holder or not. Wireless phone companies will have to honor those requests within 48 hours, and in doing so, they cannot charge a penalty fee, increase plan rates, require a new phone contract under a separate line, require approval from the primary account holder if that account holder is not the survivor, or prevent the portability of the survivor’s phone number so long as that portability is technically feasible.

Also, in severing a shared phone contract, companies must also sever a contract for any children who are in the care of a survivor.

The bill specifies, though, that survivors who make these requests will have to show proof of an abuser’s behavior by submitting one of two categories of information. Survivors can submit “a copy of a signed affidavit” from licensed social workers, victim service providers, and medical and mental health care providers—including those in the military—or a survivor can submit a copy of a police report, statements provided by police to magistrates or judges, charging documents, and protective or restraining orders.

The second core component of the bill would require phone providers to hide any records of phone calls or text messages made to domestic violence hotlines. As the bill states, those providers must “omit from consumer-facing logs of calls or text messages any records of calls or text messages to covered hotlines, while maintaining internal records of those calls and messages.”

This provision would not come into effect until 18 months after the bill passes, and it would require the US Federal Communications Commission to create a database of those hotlines, providing updates every quarter. This section would also apply to providers of both wireless and wired phone services.

A possible stalkerware intersection

The third component of the Safe Connections Act could help survivors who are also facing the threat of stalkerware. The bill would enroll survivors who have severed their contract under the new powers of the bill into the government’s Lifeline phone assistance program “as quickly as feasible,” with a period of coverage in the program for a maximum of six months.

The Lifeline program, run by the FCC, attempts to provide subsidized phones and phone services to low-income communities. Extending program eligibility to survivors could help them physically escape their situations while offering them a quick opportunity to regain digital independence.

In fact, in Malwarebytes’ continued work to protect users from the threat of stalkerware, it has learned that many of those who suffer from stalkerware tracking often have to leave their cell phones behind and start with entirely new devices.

As Chris Cox, founder of Operation Safe Escape, told Malwarebytes Labs last year when discussing how to help survivors of domestic abuse who have encountered stalkerware on their devices:

“What we always advise, consistently, if an abuser ever had access to the device, leave it behind. Never touch it. Get a burner,” Cox said, using the term “burner” to refer to a prepaid phone, purchased with cash. “You have to assume the device and the accounts are compromised.”

With access to the Lifeline program, that purchase of a new device could become more feasible.

Unfortunately, the benefits of the Lifeline program must be looked at comprehensively. Last year, Malwarebytes Labs discovered that two Android devices offered through the Lifeline program actually came with pre-installed malware. The devices are no longer available through Assurance Wireless, which was the supplier contracted with the Lifeline program, but the broader point remains: No one should have to suffer lowered cybersecurity because of their income. With the Safe Connections Act, we hope that the Lifeline program’s unfortunate mishap does not repeat, harming even more communities.

Resident Evil 8 just the latest game plagued by fake demos and early access scams

There’s been a number of scams targeting fans of major upcoming video game releases over the last week or two. Why is this happening, and what can you do to ensure both you and your children avoid such fakeouts?

Preview power: the 80s and 90s

Back in the 80s, games reviews were only really found in dedicated gaming magazines like ZZap!64 or Amstrad Action. A couple of magazine publishers had the idea to distribute full games and demos on cassette tapes mounted to the cover. This led to some spectacular covertape related magazine warfare, distribution of games without permission, and copyright breach extravaganzas.

Downloadable demos: 2000s and beyond

When net-connected consoles blasted their way into homes from around the time of the original Xbox onward, this granted a second life to the old cover tapes and discs. Consoles came with demos pre-loaded, you could download demos or full games, and update purchased titles on the fly.

Consoles going digital slowly came with its own problems. Even so, the digital download revolution encouraged new funding models and ways to play games. Early access, where players are granted first look at a title by paying or for free, is where our latest scam lies.

What are the scammers doing?

Scammers are using demos and early access promises as bait for phishing and other forms of attack. The upcoming Resident Evil title, Village, currently has a spin-off demo version called “Maiden” on the Playstation 5 with other versions to follow. Enterprising phishers are distributing fake mails offering “Early access invitations” to play Village itself, which is the full game, set after the events of Maiden.

In this way, they’re trying to ride the wave of popularity for Maiden by encouraging people to get their hands on the rest of the content. The game developers, Capcom, also mention avoiding any files offered up by the phish. This sounds very much like the phishers were also dabbling in malware distribution.

We bring tidings. Bad tidings.

The full Capcom message sent to press reads as follows:

We’re sending this message as we’ve been made aware that there are currently emails circulating that pretend to contain “Early Access invitations” to Resident Evil Village. The sender address is being displayed as “no-reply(at)capcom(dot)com”.

We want to inform you that these messages are NOT from Capcom and appear to be phishing attempts by an unauthorized third party. If you have received such a message, please DO NOT download any files or reply, and delete the message immediately.

If you are unsure of the authenticity of correspondence from Capcom, please contact us directly to verify.

This is perfect bait for younger gamers who may not be aware of this type of scam attempt. No doubt it’ll have caught out many an adult gamer, too. That’s the most recent attempt at tricking people with fake early access. Shall we take a look at a slightly earlier effort?

Fake Beta build scammers come for Far Cry

Far Cry 6 is the soon to be released entry into Ubisoft’s unstoppable game series. Last month, a supposed “beta” build of the game was mentioned in emails to various influencers / content creators in the gaming space. The mail, flagged as being under embargo, comes complete with an access password. When the password is entered, and we’re not sure if they mean to open a zip or on a fake website, an infection is downloaded to the PC. According to potential victims, it “watches your screen and records everything you do”.

That’s bad enough. This is by no means the end of the wave of fake beta/early access/demo invites though.

Gaming a wide audience

In January, THQ Nordic warned of scam mails related to their game Biomutant. As with the other missives, it seems to focus on content creators / developers. Seeing developers state that no early builds of games are being mailed to people is bad news. Could one group specifically be trying this early access build gimmick? Or is everyone at it? Quite often, a new way to go on the offensive is posted to underground forums and then people go off and try it. That could be what is happening with these attacks, or it could just be coincidence.

As far as fake betas go, those have been around for a long time. A good example of this is Cyberpunk 2077, back in July of last year. How about a Fortnite Android beta scam from 2018? We can certainly round things out with a Valorant themed, malware laden closed beta key generator from last April.

Some tips to avoid fake beta/access scams

  1. At least some of these attacks are targeted towards gaming influencers or people with big platforms. As a result, this means you may not encounter a few of them. If you do fall into this category, basic security hygiene applies. Check the security of all your accounts and enable two-factor authentication if it’s available. Run up to date security software, and ensure all your devices are patched and up to date.
  2. Begin locking down your gaming accounts if you haven’t already. It might not just be your PC at risk from attacks. They could be after your console logins / details too. All major gaming consoles have plenty of security features. It’s well worth digging out their security documentation and shoring up any gaps in your defence.
  3. If a games developer emails you out of the blue, it’s fairly easy to figure out what’s real and what isn’t. Major titles announce betas, and early access programs clearly on websites, social media, and gaming portals. It isn’t left to random mail shots and mysterious attachments. If there’s no evidence of whatever you’ve been sent in some sort of official capacity, steer clear. Worst case scenario, you can always contact most developers on social media. They will likely be happy to help if what you’re showing them is a scam.

Press X to continue?

We recommend telling younger gamers in your household about these scams, and also the security solutions used to address them. The “exclusive preview build” technique aimed at influencers probably won’t remain aimed at them exclusively for very long, so watch out for that. You may as well get ahead of the game now before the inevitable next wave of beta invite scams land in mailboxes near you. There’s always something to think about in video game land.

Report reveals the staggering scale of Business Email Compromise losses

Internet crime is ever present, and with the ongoing pandemic, levels of scams and fraud were exceptionally high in 2020. Opportunistic fraudsters didn’t give a second thought to riding the COVID-19 wave and preying upon those who are truly in need of help, or those who truly want to help.

The Internet Crime Complaint Center (IC3), an arm of the FBI where internet users can report online fraud crimes, recently released the 2020 Internet Crime Report, an annual report that contains high-level information on suspected fraud cases reported to them and their losses. A state-by-state statistical breakdown of these cases were included in an accompanying report, 2020 State Reports, that you can browse through here.

The IC3 has found that the three biggest complaints they received in 2020 are phishing scams, which garnered the highest number of complaints (241,342), ransomware (2,474), and, perhaps the most striking of these, Business Email Compromise (BEC) (19,369). It’s striking, not because of the number of complaints but because BEC scams recorded the highest total losses by victims, at roughly $1.8 billion USD. Although phishing led to the highest number of complaints, victims “only” lost $54 million USD, a fraction of the money lost to BEC scams.

According to IC3, BEC can also be called Email Account Compromise (EAC). It may or may not involve a layered attack, depending on how a threat actor can better mimic the person they’re spoofing, and how much their target employee would be able to buy into the overall deception.

It starts off with an email, either from a compromised account or spoofed address, to make it look like it originated from a particular sender. The threat actor, usually posing as a higher-up within a company, contacts a more junior employee in the company who is cleared to perform funds transfers. The attacker gives the junior employee a plausible but urgent instruction to make a large, confidential transfer of money to a fake supplier.

“In 2020, the IC3 observed an increase in the number of BEC/EAC complaints related to the use of identity theft and funds being converted to cryptocurrency,” according to the report. “In these variations, we saw an initial victim being scammed in non-BEC/EAC situations to include Extortion, Tech Support, Romance scams, etc., that involved a victim providing a form of ID to a bad actor. That identifying information was then used to establish a bank account to receive stolen BEC/EAC funds and then transferred to a cryptocurrency account.”

We remind businesses, regardless of sector, to be aware of BEC attack trends and be very vigilant in combatting it. BEC scams rely, in part, on the pressure that junior employees feel when asked to comply with demands from senior employees, and told not to alert anyone else. Employees should be empowered to seek advice and take the time they need.

Also, if your company doesn’t have an extra layer or two of authentication before the request to transfer money is green-lit, put one in place now. A phone or video call is ideal.

True, these steps introduce a bit of friction into your company processes, but a little inconvenience and delay could your company millions of dollars.

Good luck!

HelloKitty: When Cyberpunk met cy-purr-crime

On February 9, after discovering a compromise, CD Projekt Red (CDPR) announced to its 1+ million followers on Twitter that it was the victim of a ransomware attack against its systems (and made it clear they would not yield to the demands of the threat actors, nor negotiate).

Cyberpunk 2077, the latest game released by CD Projekt Red and once hailed as the “most anticipated game of the decade”, was released in December 2020 with many calling it an “unplayable mess”.

No surprise then that some people suspected that enraged gamers were hitting back at the company for releasing the game in that state. But infamous ransomware hunter Fabian Wosar (@fwosar), of Emsisoft begged to differ.

Although what he said was an informed claim, we cannot say for sure what hit CDPR until a ransomware sample is retrieved and analyzed. Nevertheless, the name-check was enough to put the HelloKitty ransomware family in the headlines.

HelloKitty ransomware

The HelloKitty ransomware, also known as Kitty ransomware, was first seen in November 2020, a few months after the first variants of Egregor were spotted in the wild.

CEMIG (Companhia Energética de Minas Gerais), a Brazilian electric power company, revealed on Facebook in late December 2020 that it was a victim of a cyberattack. Succeeding reports revealed that HelloKitty was the ransomware behind it, and that this ransomware strain was used to steal a large amount of data about the company. The attack didn’t cause any damage, however, but it caused the company to suspend its WhatsApp and SMS channels, and its online app service.

This ransomware family was named after a mutex it used called “HelloKittyMutex.”

Some researchers refer to HelloKitty as DeathRansom—a ransomware family that, based on its earlier variants, merely renames target files and doesn’t encrypt them. We speculate, however, that HelloKitty was built from DeathRansom. As such, Malwarebytes detects this ransomware as Ransom.DeathRansom.

The threat actors behind HelloKitty ransomware aren’t as active as some other threat groups, so there is little information about it. Below is what we know so far.

Infection vector

According to SentinelLabs, current intelligence suggests that HelloKitty arrives via phishing emails or via secondary infection from an initial malware attack.

Symptoms

hellokitty CEMIG
HelloKitty ransom note

Systems affected by HelloKitty ransomware display the following symptoms:

1. Terminated processes and Windows services. Once it reaches an affected system and executes, HelloKitty terminates processes and Windows services that may interfere with its operation. These processes are generally associated with security software, backup software, accounting software, email servers, and database servers (to name a few). Overall, it can target and terminate over 1,400 processes and services.

It performs the termination process using taskkill.exe and net.exe, two legitimate Microsoft Windows programs.

SentinelLabs also notes that if there are processes HelloKitty cannot terminate using these executables, it then taps into Windows’s Restart Manager to perform the termination.

2. Encrypted files with .KITTY or .CRYPTED file extensions. On Windows systems, HelloKitty ransomware uses a combination of AES-128 + NTRU encryption. On Linux systems, it uses the combination AES-256 + ECDH. These encryption recipes are not known to have any weaknesses, making decryption impossible without a key.

Encrypted files will have the .kitty or .crypted file extension appended to the file names. For example, an encrypted sample.mdb file will either have the sample.mdb.kitty or sample.mdb.crypted file names.

3. Targeted ransom note. The HelloKitty ransom note is usually a plain text file bearing either the name read_me_lkdtt.txt or read_me_unlock.txt that references its target and/or its environment. For a sample content of the note, below is a portion of the CEMIG ransom note as follows:

Hello CEMIG!

All your fileservers, HyperV infrastructure and backups have been encrypted!

Trying to decrypt or modify the files with programs other than our decryptor can lead to permanent loss of data!

The only way to recover your files is by cooperating with us.

To prove our seriousness, we can decrypt 1 non-critical file for free as proof. We have over 10 TB data of your private files, databases, personal data… etc, you have 24 hours to contact us, another way we publish this information in public channels, and this site will be unavailable.

The ransom note also includes a .onion URL that victims can open using the Tor browser. URLs are different for each victim.

4. Deleted shadow copies. Similar to other well-known ransomware families like Phobos and Sodinokibi, HelloKitty deletes shadow copies of encrypted files on affected systems to prevent victims from restoring them.
