He also discovered Mac malware in the wild that allowed access to webcam photos, screenshots and key-logging, and a separate exploit that would let someone with local access to a Mac escalate their privileges to root.NOTICE: This sidebar and rules are no longer being updated. Patrick Wardle is a former NSA staffer who last year demonstrated Mac malware that could tap into live webcam and microphone feeds. There’s no reason for people not to upgrade. This attack works on older versions of macOS as well. There’s a lot of good built-in security features.

He also says that this is not a reason to hold off on upgrading to High Sierra: it’s not a newly-introduced bug. He told Gizmodo that the company is likely to do so soon. It works equally well in signed apps.Īs a responsible researcher, Wardle reported the vulnerability to Apple on September 7 and will not disclose the method used until Apple has patched it. The demonstration video shows it running in an unsigned app, which are blocked by default in macOS, but Wardle says this was only to demonstrate how low the security bar is set. The app is able to do this without any user intervention. But Wardle demonstrated his app was able to extract and decrypt passwords for Twitter, Facebook, and Bank of America.

What is supposed to happen is that only the app authorized to access a particular password can decrypt it. The vulnerability is a huge one, because Keychain data is secured by 256-bit AES encryption, which should make it virtually uncrackable – and because the bug affects all versions of macOS, including High Sierra … Wardle demonstrated the exploit with a proof of concept app, seen in the video below. A macOS vulnerability discovered by security researcher Patrick Wardle allows any app – signed or unsigned – to extract plain text passwords from Keychain.
