However, the more time that passes without a fix, such a step might be more worthwhile. How long that takes is anyone's guess, so in the immediate future, there's probably no need to worry about it. Apple macOS High Sierra Exploit Lets Hackers Steal Keychain Passwords in Plaintext Apple yesterday rolled out a new version of its macOS operating system, dubbed High Sierra 10.13a few hours before an ex-NSA hacker publicly disclosed the details of a critical vulnerability that affects High Sierra as well as all earlier versions of macOS.

Given the presence of the video, it's incredibly likely that hackers will be able to glean enough information to reproduce it, build an attack around it and begin using it. As of now, the exploit has apparently not been used in the wild. Is it worth it? The short answer is maybe. This, however, is not the default configuration and is highly inconvenient. In the meantime, however, users can protect themselves from this type of an attack by locking the login Keychain with an additional password. Even if it is, there has been no indication of a timeframe when it might be ready for rollout. Rumor has it that it can even defeat a system that has System Integrity Protection enabled.Īpparently, the exploit is capable of accessing anything in both the 'login' and 'System' keychains, but the iCloud chain is apparently not affected, given that it stores data in a different way.Īpple has made no formal statement about the exploit, so it's unclear if a fix is in the works. Based on the video, we know that the exploit does not require admin privileges, nor does it matter if Access Control Lists have been established.

So, he's decided not to provide the company with the full details of the newly discovered flaw. Here's the problem, though: he's frustrated that Apple's Bug Bounty program only applies to bugs found in iOS and doesn't include macOS. Henze has discovered other vulnerabilities in the past, so Apple was quick to take note. An independent security researcher named Henze has discovered a potentially devastating macOS exploit that's been dubbed Keychain, and he has posted a video demonstrating it in action.
