Wardle has even shared a video where we can see the exploit in action.

Wardle told Forbes has claimed that the unsigned apps on macOS High Sierra can access the information from Keychain and even show the plaintext usernames and passwords without the need of user's master password. Security researcher and ex-NSA analyst Patrick Wardle on Monday pointed out to a flaw associated with macOS that can allow hackers to steal usernames and passwords from accounts stored in Keychain.
