Many people think that Macs aren't affected by malicious software because of Apple's strong reputation for security. Microsoft has reminded people that that is not the case, as the company has identified a serious vulnerability that affects one of the most important lines of defense.
Jonathan Bar Or, Microsoft's principal security researcher, named the flaw after it. As of now, it is tracked as CVE-2022-42822.
The Gatekeeper feature of macOS doesn't work for achilles. Gatekeeper checks every time a user downloads a Mac app that is not from Apple's App Store to make sure it is free of malicious software. The app can run on a Mac. Gatekeeper will block it if it doesn't work.
He was able to find a way around it. An attribute called com.apple.quarantine is assigned to applications downloaded using internet browsers. Gatekeeper should check the file before installing it according to this attribute.
The assignment of this attribute is blocked by the man. It will be possible for a malicious file to run on macOS without Gatekeeper being triggered.
Microsoft says that macOS's Lockdown Mode isn't useful in fighting Achilles because it's designed to solve a different problem Lockdown Mode is a high-security mode in macOS that protects people who are vulnerable to cyberattacks. If you're in Lockdown Mode, you should update macOS.
The security flaw was fixed by Apple in macOS 13 (Ventura), macOS 12.6.2 (Monterey), and macOS 11.7.2 (Big sur). It shows how important it is to keep macOS up to date.
Microsoft helped Apple fix a macOS vulnerability in the past. Microsoft issued a warning in February of 2022. Gatekeeper could also be affected by this malicious software. Gatekeeper is an excellent piece of software but it isn't bulletproof.
