OpenAI has identified a compromised update from a legitimate open-source software library, Axios, which could have allowed hackers to create fake OpenAI apps. The incident occurred on March 31, when hackers hijacked a developer's account and published two infected updates to the Axios library. The company has not detected any signs of any damage to iOS, Android, Windows or other platforms' apps. However, it has stated that users have a 30-day window to update their MacOS certificate before the revoked certificate could potentially block new downloads and new launches.
