IT NEWS

Researchers are reporting the discovery of malware targeting YouTub content creators. The aim is to compromise accounts and then take over the victims’ channels completely.

The malware, dubbed YTStealer, has one game plan: Grabbing authentication cookies. A site gives you an authentication cookie when you log in, and your browser then uses it in place of a password until you log out. If somebody can steal the authentication cookie from your browser they can use it log into whatever website you’re using, as if they are you.

Armed with YouTube cookies, YTStealer plunders YouTube accounts, and their real owners have some customer support chats waiting in their immediate future.

Targeting interests

How do malware distributors reel in YouTube channel owners in the first place? Like so many of these scams, they promote a variety of bogus applications designed to lure victims. The rogue apps don’t just install YTStealer though, they also drop several other malicious files, depending on which installer is used. Vidar and RedLine may also be present.

Several popular (fake) versions of editing and design tools, which would naturally appeal to people in video circles, are on offer. Adobe Premiere Pro, HitFilm Express, and Filmora are some of the fake installers mentioned.

Games, too, are a popular revenue stream on YouTube with game streamers and reviewers galore. No surprise, then, that fake installers and cheats for titles like Call of Duty and Grand Theft Auto are along for the ride.

The final group of bogus files relate to imitation security products and supposed cracks for Discord Nitro and Spotify Premium.

System checks and balances

Once installed on a target machine, YTStealer performs some checks to see if its running inside of a virtual machine. This is to see if the malware is being analysed by security researchers. If detection takes place, files like YTStealer will typically terminate or become incredibly stubborn.

With this out of the way, YTStealer proceeds to harvest authentication cookies and fire up a browser in “headless” mode (a browser with no windows to look at). In other words: A silent, invisible browser. The victim is completely unaware of what’s happening. Swiped cookies are loaded into the phantom browser, which can now log in to YouTube as the victim.

The malware harvests the victim’s subscriber count, channel name, age of channel, verification status, and whether or not the channel is monetised. The data is collected, encrypted, and sent to the Command and Control (C2) server tied to the malware.

How to avoid malware aimed at Youtubers

• Scammers will target your interests, and try to interest you in cheap / free copies of software related to the content you create. Is a stranger really going to give you free editing tools worth a few hundred dollars? Almost certainly not. “If it sounds too good to be true,” and all that.
• Many of these files insist you turn off security protection prior to installing. Ask yourself why they’d want you to do this, and then make a sharp exit.
• Are they directing you to a YouTube channel of their own for the download links? Check the comments. Are they disabled? Is every single comment positive, and posted from new / low quality accounts? There’s a reason for that…
• Free cheat tools advertised on YouTube are not going to work. Bypassing anti-cheat protection in major video game titles is big business, and people pay to use these tools. Anything given away for free in this manner will do little beyond infect your system.

Organisations working in the immigration sector are advised to be on high alert for Advanced Persistent Threat (APT) attacks. Bleeping Computer reports that European organisations, specifically, are under threat from the Evilnum hacking group.

Evilnum, on the APT scene since 2018 at the earliest and perhaps most well known for targeting the financial sector, appears to have switched gears.

In times of conflict

The observed attacks seem to have sprung into life on or around the beginning of the invasion of Ukraine. This is quite worrying for several reasons:

• Immigration organisations in Europe are still impacted by the fallout from COVID-19. Additionally, Government immigration services continue to be non-functional or afflicted with severe delays in processing. The UK, which set up a dedicated visa for Ukrainian refugees, has experienced processing delays for unrelated visas of up to 6 months as a result of this project. Being targeted with malware could impact crucial services still further, putting people at risk.
• Huge amounts of sensitive data is passing to and from independent immigration organisations related to the invasion of Ukraine. Exfiltration of this data could put people both outside Ukraine and those still there at risk of significant harm.
• Many volunteer organisations have sprung up to support efforts related to Ukraine. Many of these have little to no funding and are being run by random groups of immigration lawyers with minimal experience of cybersecurity issues. This is, unfortunately, an area of potential rich pickings for attackers.

Important attack details

The APT group targeted an Intergovernmental organisation (IGO), an entity created via treaty which involves two or more nations to work on issues of common interest. This attack, then, is at the highest level in terms of immigration related impact.

It begins, as so many attacks do, with a targeted email containing a rogue attachment. Opening the attached Word document fires up a message which claims that the document was created in a later version of Microsoft Word. It explains how to enable editing in order to view the supposed content, typically called “Compliance” but also “Complaint” or “Proof of ownership”, among others.

Heavily obfuscated JavaScript decrypts and deposits an encrypted binary and a malware loader (which loads up the binary), and creates a scheduled task to keep things constantly ticking over. File system artefacts created during execution are designed to imitate legitimate Windows binary names, to assist in detection avoidance.

The aim here is to create a backdoor on infected systems. Machine snapshots are taken and sent back to base via POST requests, with exfiltrated data in encrypted form.

Cybersecurity, just from a different point of view

Refugees from Ukraine are being assisted by multiple organisations that were set up after the initial invasion. Lawyers helping to run these groups may not be fully immersed in cybersecurity. However, they follow strict rules and regulations with regard to client data by default. As a result, they’re often doing security-centric things to keep client data secure without perhaps noticing the crossover.

For example: Most immigration lawyer/client interactions in the UK currently are remote, partly due to COVID-19 and partly because the UK’s visa system is now almost entirely online. As a result, pretty much everything involving sensitive documentation begins life in the form of an email. This sounds bad at first glance; however, this isn’t the case. Lawyers and clients aren’t emailing important documents in plaintext. Instead, they’re making use of encrypted documents, secure file uploads, and deleting data as and when required.

Tips for immigration orgs

If you’re a small organisation looking to help with visa or refugee processes for Ukrainians fleeing the invasion, here’s some of the things you can make a start on now to help keep things secure:

• Ensure your website is HTTPs. Most sites I’ve seen in this realm use a combination of contact email and/or web form. You don’t want sensitive information intercepted because of insecure websites. As few people as possible should have admin access to the site, and anything related to publishing. Use as few extensions and plugins as possible. Paying for domain anonymity services is useful if required.
• Consider using an alias for public facing email addresses. Additionally, lock down all email addresses with multifactor authentication (MFA). The same goes for backup/recovery emails tied to the main account(s).
• If you have the choice of SMS codes or authentication apps/hardware based security keys for 2FA, choose the latter. SMS won’t work with no signal reception, and fraudsters may divert your SMS codes via SIM swapping.
• Consider using a password manager for organization-specific passwords. If you need to share logins, use a management tool which allows you to share logins without revealing the password itself. Should you land on a phishing site, your password manager won’t pre-fill your details into the bogus portal.

I’ve spoken to individuals from several UK-based immigration organisations, including those focused on helping Ukrainians. At this point, none of them report having been targeted by attacks similar to the above. However, those organisations are absolutely in the spotlight for anyone potentially up to no good. If you’re in this line of work, or you’re just getting started, consider where and how you can begin to get things locked down right now.

The FBI has warned businesses of an uptick in reports of criminals applying for remote work using deepfake and stolen PII (personally identifiable information).

A deepfake is essentially created or modified media (image, video, or audio), often with the help of artificial intelligence (AI) and machine learning (ML). Deepfake creations are designed to appear and sound as authentic as possible. Because of this, they’re difficult to spot unless you know what to look for.

Years of data breaches made millions of Americans’ identities available for anyone with ill intent to gather and use for personal gains. This time, criminals seem confident about pulling off a scheme that fully intends to sabotage or steal from companies that hire them while keeping their true identities intact.

Armed with compelling synthetic images and videos with legitimate PII, we can imagine criminals likely getting the job before pulling the wool over their employer’s eyes.

Most open positions identified in the report were in the technology field, such as IT (information technology), computer programming, database, and software. The FBI has also noted that some positions criminals are trying to fill would grant them access to PII, financial data, corporate databases, and proprietary information.

Fortunately for organizations, there is a glaring flaw to an otherwise masterful execution of deceit: the deepfakes the criminals use suffer from sync issues.

“Complaints report the use of voice spoofing, or potentially voice deepfakes, during online interviews of the potential applicants. In these interviews, the actions and lip movement of the person seen interviewed on-camera do not completely coordinate with the audio of the person speaking. At times, actions such as coughing, sneezing, or other auditory actions are not aligned with what is presented visually.”

~ FBI, PSA number I-062822-PSA

Misuse of stolen PII is spotted with a pre-employment background check. So even if an interviewer puts the desyncs in a deepfake video down to a dodgy connection, criminals won’t be able to escape findings from a standard background check.

TechCrunch said the most at-risk businesses from criminals entering the job market this way are startups and SaaS (software as a service) companies. This is because these potentially hold lots of data or access to it “but comparatively little security infrastructure compared with the enterprises they serve or are attempting to displace.”

If you’re worried that your data might be used to get criminals into the same sector as you are, there’s not much to do apart from remaining alert and keeping an eye out for strange emails or phone calls.

Stay safe!

Amazon has patched a flaw in the Amazon Photos app which could have allowed an attacker to steal and use a user’s unique access token that verifies their identity across multiple Amazon APIs.

That would give attackers access to a trove of information, since many of these APIs contain personal data, such as names, email addresses, and home addresses.

Amazon Photos, previously known as Prime Photos, is a service related to Amazon Drive, the company’s cloud storage application. To date, it has been downloaded more than 50 million times from the Play Store. The Photos app is geared towards the storing, organizing, and sharing photos and videos.

Due to a misconfiguration of a component in the app, rendering a client’s access token severely unprotected, a third-party malicious app could access and use this token. In a ransomware scenario, threat actors could steal, delete, and encrypt files and leave affected users with no means to restore them.

To put it plainly, it’s like sending a password over to another app in plain text, the researchers who found the bug explained.

The researchers from Checkmarx informed Amazon in November 2021. The following month, the company issued a patch for the vulnerability.

Because this flaw also affects Amazon Drive, threat actors could theoretically modify files while erasing a user’s history, effectively rendering original content irrecoverable.

Erez Yalon, Checkmarx’s vice president of security research, was quoted in an interview with The Record:

“We know there is nothing completely secure in the software world. But seeing that kind of vulnerability in the software of Amazon, one of the leading companies in the world when it comes to security practices, means that it can happen to every software company.”

An Amazon spokesperson also told The Record they found “no evidence that sensitive customer information was exposed as a result of this issue.”

“We appreciate the work of independent security researchers who help bring potential issues to our attention,” the spokesperson said.

Researchers have analysed a campaign leveraging infected SOHO routers to target predominantly North American and European networks of interest.

The so-called ZuoRAT campaign, which very likely started in 2020, is so sophisticated that the researchers suspect that there is a state sponsored threat actor behind it.

SOHO routers

SOHO is short for small office/home office and SOHO routers are hardware devices that route data from a local area network (LAN) to another network connection. Modern SOHO routers have almost the same functions as home broadband routers, and small businesses tend to use the same models. Some vendors also sell routers with advanced security and manageability features, but most SOHO devices are only monitored in exceptional cases.

Which is probably the reason why the ZuoRAT managed to fly under the radar for so long.

Compromise the router

The first step in the campaign is to take control of the router. The researchers identified infected routers of several manufacturers including popular brands like ASUS, Cisco, DrayTek, and NETGEAR. It is likely that the threat actor used unpatched vulnerabilities to steal credentials from the targeted routers. Although patches for these vulnerabilities exist, it is not uncommon for device administrators never to apply these patches.

This lack of security is often caused by lack of awareness. And the lack of awareness starts by small business owners not knowing which type or model of router they have exactly. So even if they read about a vulnerability in their router, it may not sink in that it applies to them. The rebranding of routers by providers is another contributing factor to the owners’ ignorance.

Drop the RAT

The vulnerability or chain of vulnerabilities allow the threat actor to download a binary, then execute it on the host. Once installed, ZuoRAT enumerates the devices connected to the infected router. The threat actor can then use DNS hijacking and HTTP hijacking to cause the connected devices to install other malware.

The ZuoRAT agent framework enables in-depth reconnaissance of target networks, traffic collection and network communication hijacking. Some of the functions will run by default, while others might be intended to be called by additional commands.

Mirai

ZuoRAT looks like a heavily modified version of the Mirai malware. The authorities may have caught the Mirai creators, but the spirit of their botnet lives on. Numerous groups took advantage of the open-source code to create mini variants. But the command and control infrastructure used in this campaign is intentionally complex in an attempt to conceal what’s happening.

Attribution

While attribution is always hard, the researchers listed several indications that the group behind this campaign might be of Chinese origin. One set of C2 infrastructure controlled by this threat actor and used to interact with the Windows RATs was found to be hosted on internet services from China-based organizations. Also, some of the program database paths contained Chinese characters, while others referenced “sxiancheng”, a possible name or Chinese locality.

China is a likely candidate even if it seems they have already bitten off more than they can chew. According to an article in the Financial Times Chinese university students have been lured to work as translators to help identify hacking targets, and to analyze stolen material.

DNS hijacking

Using the gathered information about the DNS settings and the internal host in the adjacent LAN, there were several functions designed to perform DNS hijacking. Some functions allowed the threat actor to update DNS hijacking rules specifying which domains to hijack, the malicious IP address resulting from the hijack and the number of times to trigger the rule.

HTTP hijacking

Another noteworthy function enabled the actor to specify which client or subnet to hijack. It hijacked the process so that it could match the traffic pattern. If the pattern matched one of the rules, it displayed a 302 error that redirected the client’s browser to another location where the threat actor could manipulate the connection.

Mitigation

If you fear that your router has been compromised, simply restarting an infected device will remove the initial ZuoRAT exploit. To fully recover, however, a factory reset clears infected devices.

To avoid your router from getting infected, find the most recent firmware and install it so you have all the latest patches.

Systems that used an infected route for their internet access and used no block lists that included the C2 infrastructure of ZuoRAT may be infected. This is not only true for Windows systems. The researchers found samples written in GO, which is a cross-platform language.  

IoCs associated with this campaign for threat hunting can be found on the Black Lotus Labs GitHub page.

Stay safe, everyone!

Mozilla released version 102.0 of the Firefox browser to Release channel users on June 28, 2022.

The new version fixes 20 security vulnerabilities, five of which are classified as “High”. The new version also comes with a new privacy feature that strips parameters from URLs that track you around the web.

Vulnerabilities

Publicly disclosed computer security flaws are listed in the Common Vulnerabilities and Exposures (CVE) database. Its goal is to make it easier to share data across separate vulnerability capabilities (tools, databases, and services). These are the CVEs we think you should know:

High

CVE-2022-34479: A malicious website that could create a popup could have resized the popup to overlay the address bar with its own content, resulting in potential user confusion or spoofing attacks. This bug only affects Firefox for Linux. It does not apply to other operating systems.

CVE-2022-34470: Use-after-free in nsSHistory. Use after free (UAF) is a vulnerability caused by incorrect use of dynamic memory during a program’s operation. If after freeing a memory location, a program does not clear the pointer to that memory, an attacker can use the error to manipulate the program. Navigations between XML documents may have led to a use-after-free and potentially exploitable crash.

CVE-2022-34468: CSP sandbox header without ‘allow-scripts’ can be bypassed via retargeted javascript: URI. An iframe that was not permitted to run scripts could do so if the user clicked on a javascript: link.

CVE-2022-34484: Memory safety bugs fixed in Firefox 102 and Firefox ESR 91.11. Some of these bugs showed evidence of JavaScript prototype or memory corruption, and with enough effort some of these could have been exploited to run arbitrary code.

Moderate

CVE-2022-34482 and CVE-2022-34483: Two separate issues with the same effect. Drag and drop of malicious image could have led to malicious executable and potential code execution. An attacker who could have convinced a user to drag and drop an image to a filesystem could have manipulated the resulting filename to contain an executable extension.

CVE-2022-34478: The ms-msdt, search, and search-ms protocols deliver content to Microsoft applications, bypassing the browser when a user accepts a prompt. These applications have had known vulnerabilities, exploited in the wild, so in this release Firefox has blocked these protocols from prompting the user to open them.

New privacy feature

Many companies involved in advertising use custom URL query parameters that enable them to track clicks on links. The most well-known example is probably the ?fbclid= parameter that Facebook adds to outbound links.

With the release of Firefox 102, Mozilla has added the new “Query Parameter Stripping” feature that automatically strips some of these query parameters. It does not matter whether you clicked on a link or pasted the URL into the address bar.

To enable Query Parameter Stripping, go into the Firefox Settings, click on Privacy & Security, and then change Enhanced Tracking Protection to Strict.

You will need to click Reload All Tabs to apply the changes. If you find that setting Enhanced Tracking Protection to Strict could causes issues with certain sites, you can use the Manage Exceptions option to add these websites, or use the “Custom” setting to choose which trackers and scripts to block.

Updating

Under normal circumstances, updates will be applied without user intervention. You can check for the version number in the products’ menu under Help > About

Should you not be using the latest version for some reason, e.g. automatic updates are disabled, then this screen will inform you that a new version is available and will start downloading it.

When it’s done, you’ll see a prompt to restart the browser. This will apply the update.

Stay safe, everyone!

Omegle reached the heady heights of fame when everyone least expected it. Thanks to TikTok influencers, children flocked to this 13-year-old platform during the pandemic, unaware of the dangers already there.

The concept of talking to strangers online is Omegle’s main selling point, but it’s not new. When you think about it, most of us always engage with strangers on online platforms that promote conversations and debate or inspire reactions.

But unlike other social sites, Omegle has scant security to protect anyone willing to take that risky but exciting dive. Users are, once again, left to fend for themselves as they explore an online world through a platform where the only thing simple is its interface.

So what are the things every parent, potential and current user, or school personnel should know about; and what can they do to protect themselves and the children in their care?

What do you need to sign up for Omegle?

Nothing. Unlike other popular social networking sites, users wanting to try out Omegle don’t need to sign up and create a profile. You just need to visit it from your computer or smartphone’s browser to start.

Once a user is signed up and paired with another user, the platform automatically sets the names to “You” and “Stranger”.

What are the risks of using Omegle?

Because people are randomly paired up for a text or video chat, anyone could meet anyone. These include VCH (virtual cam whore) puppets (which are bots), other extortionists, and impersonators (including child predators).

Content in Omegle isn’t guaranteed clean either. Your child might be exposed to nudity, grooming, privacy threats (such as strangers earning your child’s trust so they can get sensitive information from them), scams, and sexual abuse.

There is also the risk of your child being coaxed into exposing themselves and their younger siblings, or performing sexual acts. Child predators and extortionists do this so they can sell the clips, keep them for personal use, or use them in other extortion campaigns to lure more Omegle users into participating in sexual acts. Remember that the majority of these incidents happen in a house where parents and other family members are present.

Lastly, your child could become a target of cyberbullies. One TikTok user documented his experience of racism while using Omegle to TikTok users. Dr. Joanne Meredith, a cyberpsychologist, said the incident is a consequence of people losing their inhibitions online.

“Due to various features of online interaction—including dissociative imagination, or the view that the online world is a kind of game—people become less inhibited and behave in ways that they would not normally.”

Does Omegle have any parental controls?

No, none.

What other features does Omegle have?

Omegle used to have what it called “Spy Mode” (or “Spy (question) mode”), wherein the “spy” becomes the third party in a conversation between two strangers. The “spy” can ask questions for them to answer, or the “spy” could just listen in on the conversation without contributing.

This has now been removed, reportedly because it was being used to sell child pornography.

Another feature is the College Student Chat, where curious college students can enter their student email addresses before getting paired with others enrolled in their school.

Finally, there is the Adult chat function, which is free for kids to access.

Is Omegle safe for kids?

I think you know the answer to that at this point.

If your child looks up to a TikTok influencer who encourages followers to use Omegle, explain that it is not a safe place to meet other people online because it doesn’t have safeguards, unlike other social media platforms.

Staying safe on Omegle

It is better for parents, carers, and other responsible adults to deter their young persons from using Omegle altogether until they are 18. Personally, this is a non-negotiable because of the lack of safeguards and high risk of children being targeted, especially if they are young teen girls.

Any one-on-one stranger video chat platform like Omegle is risky for kids. It is paramount to keep an open and healthy communication with your child regarding this.

If you have found out your child has or continues to use Omegle, it’s time to sit them down for a quiet chat. Never punish them for being curious. Instead, let them know about the risks in order to explain why they need to stop using the platform until they’re at the right age.

Should your young person insist on using stranger video chat apps despite knowing the risks and repeated warnings, then do whatever you can to keep them from reaching these sites. Blacklist them locally using your security solution of choice with a web filter feature on your browser, on Windows via the HOSTS file (but take care not to put a lot of URLs there) or on a Mac.

Good luck!

In the continued saga of annoying search extensions we have a new end-of-level boss.

Victims have been reporting browser extensions that were removed by Malwarebytes, but “magically” came back later. Since the victims also complained about the message saying their browser was “managed”, we had a pretty good idea where to look.

Search extensions

The culprits turned out to be search extensions. Which is often the case when we spot potentially unwanted programs (PUPs) that use malware tactics to get installed and gain persistence.

The search hijackers “active search bar” and “custom search bar” were both available in the Chrome web store at the time of writing even though we reported them days ago.

PowerShell

It took some digging to find the origin, since all we had were the extensions. And when the extensions were installed directly from the webstore, nothing happened out of the ordinary. However, some hunting on VirusTotal soon led me to a few recently uploaded PowerShell scripts that included the string “ExtensionInstallForcelist.” I looked for that string because we know from the past that these registry policies account for the “Your browser is managed” warnings.

$CPath = "HKLM:SOFTWAREPoliciesGoogleChromeExtensionInstallForcelist";

$EPath = "HKLM:SOFTWAREPoliciesMicrosoftEdgeExtensionInstallForcelist";

The description in the Chromium documentation about the ExtensionInstallForcelist states:

“Specifies a list of apps and extensions that are installed silently, without user interaction, and which cannot be uninstalled nor disabled by the user.”

And to confirm this finding, the victims that provided logs all had one of these PowerShell script listed in their Scheduled Tasks.

The Scheduled Task was set to run every four hours, which explained why the extensions kept coming back.

Installer

But Scheduled Tasks don’t install themselves either and dropping PowerShell scripts in the System32 folder requires Administrator privileges, so we needed to dig a little further to find an installer.

The domain wincloudservice.com was used as a download location in all the PowerShell scripts so we used that domain as a search parameter in our next stage of VirusTotal hunting. This search eventually returned three installers. What they had in common at first glance was that the filenames all ended with “_x64LTS.exe” and that they were all signed by “Tommy Tech LTD.”

Upon further inspection we noticed that the installers all asked for Administrator privileges twice. The first part installs something that is called “Setup” and the second part installs an application that aligns with the name of the installer. So, it appears that the original installer files were “patched” to add the installer for our browser hijacker. It stands to reason that these installers are offered for download somewhere by the threat actors.

The EULA points to tommytechil.com which is unreachable. I was unable to find an installer that actually dropped an extension in Edge, but the “Your browser is managed by your organization” setting does get enforced.

Javascripts

Malwarebytes customers were protected against these extensions as Malwarebytes’ web protection module blocked the domain wincloudservice[.]com. On inspection, this domain hosted several javascripts including heavily obfuscated files called crypto.js and crypto-js.min.js.

Detection and removal

Malwarebytes detects these browser hijackers as PUP.Optional.ActiveSearchBar and PUP.Optional.CustomSearchBar. Included in the removal procedure are the extension, and the Scheduled Task, which is enough to permanently get rid of the extension.

Some Windows registry changes have been made that will take a system administrator to decide what they want to keep or not.

The registry keys to remove the “Your browser is managed” are:

HKEY_LOCAL_MACHINESOFTWAREPoliciesGoogleChromeExtensionInstallForceList

HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftEdgeExtensionInstallForceList

And another change made by the installer was the registry value:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftPowerShell1ShellIdsMicrosoft.PowerShell\ExecutionPolicy

The installer set that to “Unrestricted” which may not be your favorite setting. If you are not sure or you have never actively set that policy, the default is “Restricted”. Please note that in some organizations PowerShell is required to run.

The post Forced Chrome extensions get removed, keep reappearing appeared first on Malwarebytes Labs.

Google’s Threat Analysis Group (TAG) has revealed a sophisticated spyware activity involving ISPs (internet service providers) aiding in downloading powerful commercial spyware onto users’ mobile devices. The spyware, dubbed Hermit, is reported to have government clients much like Pegasus.

Italian vendor RCS Labs developed Hermit. The spyware was spotted in Kazakhstan (to suppress protests against government policies), Italy (to investigate those involved in an anti-corruption case), and Syria (to monitor its northeastern Kurdish region), all deployed by their respective governments.

Hermit affects Android and iOS devices and is described as a modular spyware. This means it can download pieces of itself (modules) for additional functionalities, making it customizable to suit client needs, from a C2 (command and control) server.

Unlike NSO’s Pegasus, Hermit is not as stealthy. But at its core, it functions like any government-grade spyware. It can read SMS and chat messages, view passwords, intercept calls, record calls and ambient audio, redirect calls, and pinpoint precise locations of victims.

Hermit also roots all infected Android devices, giving itself deeper access to phone features and user data. On iOS, Hermit is packed with six exploits, two of which were targeting zero-day vulnerabilities. According to Google’s report, these are the following exploits:

• CVE-2018-4344 internally referred to and publicly known as LightSpeed.
• CVE-2019-8605 internally referred to as SockPort2 and publicly known as SockPuppet
• CVE-2020-3837 internally referred to and publicly known as TimeWaste.
• CVE-2020-9907 internally referred to as AveCesare.
• CVE-2021-30883 internally referred to as Clicked2, marked as being exploited in-the-wild by Apple in October 2021.
• CVE-2021-30983 internally referred to as Clicked3, fixed by Apple in December 2021.

A Hermit spyware campaign starts off as a seemingly authentic messaging app users are deceived into downloading. A government actor also poses as a mobile carrier over SMS—sometimes with the help of the target’s ISP—to socially engineer targets into downloading the spyware masquerading as a tool to “fix” their internet connection.

Both Apple and Google have already notified their users regarding this spyware, and then some. Apple revoked the legitimate certificates Hermit abused to reside on iPhone devices, while Google beefed up its Google Play Protect security app to block Hermit from running. Google also pulled the plug on Hermit’s Firebase account, which it uses to communicate with its C2.

When questioned by TechCrunch, RCS Labs provided a statement, which we have replicated in part below:

RCS Lab exports its products in compliance with both national and European rules and regulations. Any sales or implementation of products is performed only after receiving an official authorization from the competent authorities. Our products are delivered and installed within the premises of approved customers. RCS Lab personnel are not exposed, nor participate in any activities conducted by the relevant customers.

Providers of government-grade spyware like Pegasus and Hermit always claim to have legitimate reasons for creating malware. But as we’ve seen and heard from countless reports, they are mainly used to spy on journalists, activists, and human rights defenders.

A person working in the city of Amagasaki, in Western Japan, has mislaid a USB stick which contained data on the city’s 460,000 residents.

The USB drive was in a bag that went missing during a reported day of drinking and dining at a restaurant last Tuesday. The person reported it to the police the following day.

Data on the USB drive included names, gender, birthdays, and addresses. Other additional personal details were included, though it’s not been revealed what this is. Bank account numbers of households receiving welfare also found themselves on the USB drive.

Safety first pays dividends

The one piece of good news to emerge from this story is that the drive was both encrypted and password protected. So, providing they used a good password, if someone finds the USB drive and plugs it into a computer, they won’t be able to just open up the files and view the contents.

If whoever put this drive together hadn’t bothered with security measures, the first person to find the lost drive would have a data payday on their hands. Perhaps as a result of this cautious approach, there’s been no evidence or reports of the data being leaked so far.

How to safely transfer data

There is the question of why this data was on a USB stick in the first place. According to CBSNews, it was being transferred to a call center in Osaka. There are plenty of alternatives to ferrying data around on easily lost USB sticks. While some industries have strict compliance and regulatory standards, others may simply not be able to use third-party products for a variety of reasons. Even so, anything along these lines is surely better than “I lost a USB stick on a night out”. With this caveat out of the way:

• Secure File Transfer Protocol (SFTP). This is used in business as a way to securely send files from one device to another. Files sent using this method are done so via an encrypted connection. One potential drawback here is you’ll likely need software installed on all the machines receiving the files. If you need to send data to another organisation, this can quickly become complicated or unfeasible. Additionally, not everyone believes it’s a suitable option for secure file transfer when more custom-built solutions are now available.
• Data in the cloud. Third party cloud products like Dropbox and Box allow you to store, and share, files. They both have lots to offer, with Box in particular being specifically geared towards business solutions. Multi-factor authentication, malware detection and leak prevention, encryption and compliance: it’s all there. Services like the above are increasingly more popular in business circles where secure, pain-free data transfer is required but the in-house knowledge required to do it yourself isn’t to hand.
• Encrypting your data and your USB drive. In some situations it may well be “USB drive or nothing at all”. If you’re using Windows 10 Home, you’ll need to use a third-party solution to encrypt files as the option will be greyed out. If you’re on other versions like Pro and Enterprise, the encryption option will be available to you. Right click your file(s), then select Properties -> Advanced -> Encrypt contents to secure data. As for the drive itself, you’ll once again have to rely on third-party tools if you’re running Windows 10 Home. Otherwise, you can secure the drive with Bitlocker. Mac users should select the Encrypt USB stick option from the location entry, then create and verify the encryption password. Be sure to set a password hint, too. Hit Encrypt Disk to complete the process.
