Deep Dive 1 — A Sting in the Tail on the iPhone Passcode Story
Following on from their recent excellent reporting on how criminal gangs are stealing people’s iPhones after getting their phone passcodes and then utterly ruining their digital lives by completely taking over their Apple IDs, Joanna Stern and Nicole Nguyen are back with a followup — attackers have found another way to leverage the access they are getting to phones to permanently lock victims out of their Apple IDs.
Some time ago, Apple added an optional feature where users could choose to take responsibility for their own Apple ID recovery by enabling a Recovery Key. Normally, Apple hold an Apple ID’s recovery key, and if you jump through all their hoops to prove your identity, they can let you back in to an Apple ID you’ve lost access to. For people who do not want to trust Apple, they can choose to take over the responsibility for account recovery from Apple by enabling a Recovery Key on their Apple ID. When you do this, Apple make it very clear that they will be unable (not unwilling, unable) to recover your Apple ID if you do this, and that you are taking over full responsibility for protecting and storing this vital key.
Most people don’t enable a recovery key, because having Apple able to help when you get locked out of your Apple ID is a feature for most people, not a bug!
However, as things stand, all you need to enable a recovery key on an Apple ID is:
- Access to logged-in Apple device
- The passcode for that device
You can see where this is going — attackers are observing people unlocking their phones, stealing their phones, changing the Apple ID password to lock the true owner out immediately, then setting a recovery key to lock them out permanently. They can then disable activation lock on the stolen device and sell it, without the true owner being able to remotely wipe it etc.
The only protection for now would be to set a recovery key yourself, but that’s taking on a big responsibility, so until Apple make it more difficult to set a recovery key, just remember it’s even more important than we already knew to protect your iPhone passcode!

Deep Dive 2 — Attackers are Focusing on the Mac More and More
TL;DR — the sky is not falling, there’s no need to panic, but attackers are paying ever more attention to the Mac, so the time for any lingering complacency is well and truly over!
Two news stories broke in the last few weeks to drive home this point.
- An apparently experimental Mac version of a common ransomware malware was discovered in the wild
- A Mac-specific data stealing trojan was discovered for sale on Telegram
Apple malware sleuth extraordinaire Patrick Wardle reported the discovery of what appears to be an early beta of a Mac version of the ransomware widely deployed by the notorious LockBit cyber crime gang. The good news is that the Mac malware was clearly and early-stage experiment with so many bugs it actually crashed on launch, it still shows where the attackers are focusing their attention. So, today, this version of this malware appears to pose no real risk to regular users, that’s not likely to remain the case for long 🙁
Separately, researchers as the company Cyble reported discovering a data stealer for the Mac for sale on an underground Telegram Channel. The malware was sold as a data-stealing-as-a-service toolkit for $1K per month. That shows the economic value cybercriminals see in Mac users. The malware is being advertised as Atomic macOS Stealer, or AMOS for short.
The malware is pretty powerful, stealing passwords from the keychain, interesting-looking files, passwords and form-fill-ins from all the major browsers, and draining funds from many popular crypto wallets.
The silver lining is that this is a trojan, so it relies on social engineering to trick victims into running the installer, and then, into entering their password into the Malware. That’s how it can steal the contents of users’ keychains.
