iPhone owners are reporting that photos they’d deleted are now back on their phones, after updating to iOS 17.5.

With so many users reporting similar oddities, it would seem something went wrong, or at least different than to be expected. Here are some examples from Reddit:

“When in conversation with my partner, I went to send a picture and saw that the latest pictures were nsfw material we’d made years ago”

“I have four pics from 2010 that keep reappearing as the latest pics uploaded to iCloud. I have deleted them repeatedly.”

“Same thing happened to me. Six photos from different times, all I have deleted. Some I had deleted in 2023.”

When you delete a photo from an iPhone or iPad, it goes into a “Recently deleted” album for up to 30 days to make it easy to recover if the photo is accidentally deleted. However, the above examples vastly exceed this timeframe, and it’s unclear exactly what’s happened here.

When you delete a file, actually all that happens is you remove the pointer that tells you where exactly the file is located. This makes it hard to find, but not impossible. Until the system uses the location of the deleted file and replaces it with other data, the file can be retrieved.

Apple’s last update for iOS 17.5 and iPadOS 17.5 came out on Monday with a warning to update your iPhone as soon as possible. That’s because iOS 17.5 fixes 15 security vulnerabilities, some of which are serious. Please don’t let this article stop you from installing the update, but it’s good to be prepared for some unexpected behavior.

At the time of writing, Apple hasn’t commented on the issue.

More and more websites and services are making multi-factor-authentication (MFA) mandatory, which makes it much harder for cybercriminals to access your accounts. That’s a great thing. But as security evolves, so do cybercriminals who are always looking for new ways to scam us.

A type of phishing we’re calling authentication-in-the-middle is showing up in online media. While these techniques, named after man-in-the-middle (MitM) attacks, have existed for a while, they appear to be gaining traction now.

It works like this: A user gets lured to a phishing site masquerading as a site they normally use, such as a bank, email or social media account. Once the user enters their login into the fake site, that information gets redirected by the cybercriminals to the actual site, without the user knowing.

The user is then prompted for their MFA step. They complete this, usually by entering a code or accepting a push notification, and this information is then relayed to the criminals, allowing them to login to the site.

Once the criminals are into an account, they can start changing settings like the account’s email address, phone number, and password, so the user can no longer log in, or they can simply clean out a bank account. This may help you understand why many platforms ask for your PIN or other authentication again when you try to change one of these important settings.

Victims are lured to phishing sites like these via links from social media or emails where it can be hard to identify the real link.  Phishing sites can even show up in sponsored search results, in the same way as we reported about tech support scams.

How to protect yourself from authentication-in-the-middle attacks

• Keep your wits about you. Being aware of how scammers work is the first step to avoiding them. Don’t assume sponsored search results are legit, and trust that if something seems suspicious then it probably is.
• Use security software. Many security programs block known phishing sites, although domains are often short-lived and get rotated quickly. Malwarebytes Browser Guard can help protect you.
• Use a password manager. Password managers will not auto-fill a password to a fake site, even if it looks like the real deal to you.
• Consider passkeys. Multi-factor authentication is still super-important to enable, and will protect you from many types of attacks, so please continue to use it. However, authentication-in-the-middle attacks only work with certain types of MFA, and passkeys won’t allow the cybercriminals to login to your account in this way. Many services have already begun using passkeys and they’re no doubt here to stay.

BreachForums—probably the largest dark web marketplace for stolen data to be leaked and sold—has been seized by law enforcement.

Now, both the regular and the TOR domain of BreachForums are plastered with a message telling visitors the site is now under control of the FBI.

The FBI said BreachForums and its predecessor Raidforums was:

“…operating as a clear-net marketplace for cybercriminals to buy, sell, and trade contraband, including stolen access devices, means of identification, hacking tools, breached databases, and other illegal services.”

Raidforums ran from early 2015 until February 2022. The first iteration of BreachForums was then set up in March 2022 and ran until March 2023, when US law enforcement arrested the alleged operator, “Pompompurin”, in New York.

A new administrator then rose to the occasion and said they were working on a plan to get the forum through the problems caused by that arrest. But on March 21, 2023, the new administrator announced the decision to shut BreachForums down.

Another forum administrator going by the account name “Baphomet” then took over.

According to BleepingComputer, the FBI has also seized the site’s Telegram channel, with law enforcement sending messages to the channel on behalf of the forum’s operator “Baphomet”.

BreachForums was in use just last week for a big name breach when a cybercriminal put up for sale breached customer data taken from Dell between 2017-2024.

Apple and Google have announced an industry specification for Bluetooth tracking devices which help alert users to unwanted tracking.

The specification, called Detecting Unwanted Location Trackers, will make it possible to alert users across both iOS and Android if a device is unknowingly being used to track them.

The alert would be pushed to the users device and would say “[Item] Found Moving With You.”

In many cases “[Item]” might well actually be an AirTag.

AirTags’ intended use is to let you easily track things like your keys, wallet, purse, backpack, luggage, and more. You can simply set it up with your iPhone, iPad, or iPod touch, attach it somewhere, and the AirTag will show up in your Find My app. However, AirTags have long been associated with this unwanted tracking, which is something Apple apparently did not foresee and has been working on to make this type of abuse harder.

Apple’s first step to discourage unwanted tracking was the “Tracking Notifications” option in the Find My app. This feature is available on iOS or iPadOS 14.5 or later.

Android introduced a similar “unknown tracker alert” to find trackers placed near you or in your belongings without your knowledge or consent.

With the new capability that both tech giants have pushed, users will now get the alert, regardless of the platform the device is paired with. If a user gets such an alert on their device, it means that someone else’s Bluetooth tracker is moving with them.

Android and iPhone users can view the tracker’s identifier, have the tracker play a sound to help locate it, and access instructions to disable it. Bluetooth tag manufacturers including Chipolo, eufy, Jio, Motorola, and Pebblebee have all said that future tags will be compatible.

Apple and Google will continue to work with the Internet Engineering Task Force via the Detecting Unwanted Location Trackers working group to develop the official standard for this technology.

Google has released an emergency security update for its Chrome browser. The update includes a patch released four days earlier for a vulnerability which Google say is already being exploited.

The easiest way to update Chrome is to allow it to update automatically, but you can end up lagging behind if you never close the browser or if something goes wrong—such as an extension stopping you from updating the browser.

Click Settings > About Chrome. If there is an update available, Chrome will notify you and start downloading it. Then all you have to do is relaunch the browser in order for the update to complete, and for you to be safe from those vulnerabilities.

Technical details on the vulnerabilities

If you have already updated to version 124.0.6367.201/.202 for Mac and Windows or 124.0.6367.201 for Linux, this will provide protection against the first vulnerability. The patch Google issued four days ago covered this actively exploited vulnerability.

The Common Vulnerabilities and Exposures (CVE) database lists publicly disclosed computer security flaws. The actively exploited CVE patched in this update is:

CVE-2024-4671 a use after free in Visuals in Google Chrome prior to 124.0.6367.201 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page.

Use after free (UAF) is a type of vulnerability that is the result of the 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. Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code. In this case, by exploiting the vulnerability, the attacker can escape the sandbox that should contain any threats to the browser.

Exploitation is possible by getting the target to open a specific, specially crafted webpage, so the vulnerability is suitable for exploitation as a drive-by attack.

CVE-2024-4761: An out of bounds write in V8 in Google Chrome prior to 124.0.6367.207 allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page.

An out-of-bounds write or read flaw makes it possible to manipulate parts of the memory which are allocated to more critical functions. This could allow an attacker to write code to a part of the memory where it will be executed with permissions that the program and user should not have.

V8 is Google’s open-source high-performance JavaScript and WebAssembly engine and is part of the Chromium project. Among others it runs the JavaScript code included in webpages.

Again, exploitation is possible by getting the target to open a specific, especially crafted webpage, which makes the vulnerability suitable for exploitation as a drive-by attack.

Across America, survivors of domestic abuse and stalking are facing a unique location tracking crisis born out of policy failure, unclear corporate responsibility, and potentially risky behaviors around digital sharing that are now common in relationships.

No, we’re not talking about stalkerware. Or hidden Apple AirTags. We’re talking about cars.

Modern cars are the latest consumer “device” to undergo an internet-crazed overhaul, as manufacturers increasingly stuff their automobiles with the types of features you’d expect from a smartphone, not a mode of transportation.

There are cars with WiFi, cars with wireless charging, cars with cameras that not only help while you reverse out of a driveway, but which can detect whether you’re drowsy while on a long haul. Many cars now also come with connected apps that allow you to, through your smartphone, remotely start your vehicle, schedule maintenance, and check your tire pressure.

But one feature in particular, which has legitimate uses in responding to stolen and lost vehicles, is being abused: Location tracking.

It’s time car companies do something about it.  

In December, The New York Times revealed the story of a married woman whose husband was abusing the location tracking capabilities of her Mercedes-Benz sedan to harass her. The woman tried every avenue she could to distance herself from her husband. After her husband became physically violent in an argument, she filed a domestic abuse report. Once she fled their home, she got a restraining order. She ignored his calls and texts.

But still her husband could follow her whereabouts by tracking her car—a level of access that Mercedes representatives reportedly could not turn off, as he was considered the rightful owner of the vehicle (according to The New York Times, the husband’s higher credit score convinced the married couple to have the car purchased in his name alone).

As reporter Kashmir Hill wrote of the impasse:

“Even though she was making the payments, had a restraining order against her husband and had been granted sole use of the car during divorce proceedings, Mercedes representatives told her that her husband was the customer so he would be able to keep his access. There was no button she could press to take away the app’s connection to the vehicle.”

This was far from an isolated incident.

In 2023, Reuters reported that a San Francisco woman sued her husband in 2020 for allegations of “assault and sexual battery.” But some months later, the woman’s allegations of domestic abuse grew into allegations of negligence—this time, against the carmaker Tesla.

Tesla, the woman claimed in legal filings, failed to turn off her husband’s access to the location tracking capabilities in their shared Model X SUV, despite the fact that she had obtained a restraining order against her husband, and that she was a named co-owner of the vehicle.

When The New York Times retrieved filings from the San Francisco lawsuit above, attorneys for Tesla argued that the automaker could not realistically play a role in this matter:

“Virtually every major automobile manufacturer offers a mobile app with similar functions for their customers,” the lawyers wrote. “It is illogical and impractical to expect Tesla to monitor every vehicle owner’s mobile app for misuse.”

Tesla was eventually removed from the lawsuit.

In the Reuters story, reporters also spoke with a separate woman who made similar allegations that her ex-husband had tracked her location by using the Tesla app associated with her vehicle. Because the separate woman was a “primary” account owner, she was able to remove the car’s access to the internet, Reuters reported.

A better path

Location tracking—and the abuse that can come with it—is a much-discussed topic for Malwarebytes Labs. But the type of location tracking abuse that is happening with shared cars is different because of the value that cars hold in situations of domestic abuse.

A car is an opportunity to physically leave an abusive partner. A car is a chance to start anew in a different, undisclosed location. In harrowing moments, cars have also served as temporary shelter for those without housing.

So when a survivor’s car is tracked by their abuser, it isn’t just a matter of their location and privacy being invaded, it is a matter of a refuge being robbed.

In speaking with the news outlet CalMatters, Yenni Rivera, who works on domestic violence cases, explained the stressful circumstances of exactly this dynamic.

“I hear the story over and over from survivors about being located by their vehicle and having it taken,” Rivera told CalMatters. “It just puts you in a worst case situation because it really triggers you thinking, ‘Should I go back and give in?’ and many do. And that’s why many end up being murdered in their own home. The law should make it easier to leave safely and protected.”

Though the state of California is considering legislative solutions to this problem, national lawmaking is slow.

Instead, we believe that the companies that have the power to do something act on that power. Much like how Malwarebytes and other cybersecurity vendors banded together to launch the Coalition Against Stalkerware, automakers should work together to help users.

Fortunately, an option may already exist.

When the Alliance for Automobile Innovation warned that consumer data collection requests could be weaponized by abusers who want to comb through the car location data of their partners and exes, the automaker General Motors already had a protection built in.

According to Reuters, the roadside assistance service OnStar, which is owned by General Motors, allows any car driver—be they a vehicle’s owner or not—to hide location data from other people who use the same vehicle. Rivian, a new electric carmaker, is reportedly working on a similar feature, said senior vice president of software development Wassym Bensaid in speaking with Reuters.

Though Reuters reported that Rivian had not heard of their company’s technology being leveraged in a situation of domestic abuse, Wassym believed that “users should have a right to control where that information goes.”

We agree.

Dell is warning its customers about a data breach after a cybercriminal offered a 49 million-record database of information about Dell customers on a cybercrime forum.

A cybercriminal called Menelik posted the following message on the “Breach Forums” site:

“The data includes 49 million customer and other information of systems purchased from Dell between 2017-2024.

It is up to date information registered at Dell servers.

Feel free to contact me to discuss use cases and opportunities.

I am the only person who has the data.”

According to Menelik the data includes:

• The full name of the buyer or company name
• Address including postal code and country
• Unique seven digit service tag of the system
• Shipping date of the system
• Warranty plan
• Serial number
• Dell customer number
• Dell order number

Most of the affected systems were sold in the US, China, India, Australia, and Canada.

Users on Reddit reported getting an email from Dell which was apparently sent to customers whose information was accessed during this incident:

“At this time, our investigation indicates limited types of customer information was accessed, including:

• Name
• Physical address
• Dell hardware and order information, including service tag, item description, date of order and related warranty information.

The information involved does not include financial or payment information, email address, telephone number or any highly sensitive customer information.”

Although Dell might be trying to play down the seriousness of the situation by claiming that there is not a significant risk to its customers given the type of information involved, it is reassuring that there were no email addresses included. Email addresses are a unique identifier that can allow data brokers to merge and enrich their databases.

So, this is another big data breach that leaves us with more questions than answers. We have to be careful that we don’t shrug these data breaches away with comments like “they already know everything there is to know.”

This kind of information is exactly what scammers need in order to impersonate Dell support.

Protecting yourself from a data breach

There are some actions you can take if you are, or suspect you may have been, the victim of a data breach.

• Check the vendor’s advice. Every breach is different, so check with the vendor to find out what’s happened, and follow any specific advice they offer.
• Change your password. You can make a stolen password useless to thieves by changing it. Choose a strong password that you don’t use for anything else. Better yet, let a password manager choose one for you.
• Enable two-factor authentication (2FA). If you can, use a FIDO2-compliant hardware key, laptop or phone as your second factor. Some forms of two-factor authentication (2FA) can be phished just as easily as a password. 2FA that relies on a FIDO2 device can’t be phished.
• Watch out for fake vendors. The thieves may contact you posing as the vendor. Check the vendor website to see if they are contacting victims, and verify any contacts using a different communication channel.
• Take your time. Phishing attacks often impersonate people or brands you know, and use themes that require urgent attention, such as missed deliveries, account suspensions, and security alerts.
• Set up identity monitoring. Identity monitoring alerts you if your personal information is found being traded illegally online, and helps you recover after.

Medical health care provider DocGo has disclosed in a form 8-K that it experienced a cybersecurity incident involving some of the company’s systems. As part of the investigation of the incident, the company says it has determined that the attacker accessed and acquired data, including certain protected health information.

DocGo is a healthcare provider that offers mobile health services, ambulance services, and remote monitoring for patients in 30 US states, and across the United Kingdom. On its company website it touts over 7,000,000 patient interactions.

In the same form, DocGo says the breach concerns a limited number of healthcare records within the company’s US-based ambulance transportation business, and that no other business lines have been involved.

DocGo says it is actively reaching out to those individuals who had their data compromised in the attack.  

So far, we have no indication what the nature of the cyberattack was, but it is almost standard procedure nowadays for ransomware groups to use stolen data as extra leverage to get the victim to pay the ransom.
