Experts claim to have found more weaknesses in Apple's Gatekeeper tool — but it doesn't seem too bothered

Summary

Security researchers claim a bypass for Apple's Gatekeeper by replacing a previously run legitimate app with malware. Apple dismissed the issue, stating locally rebuilt bundles are outside Gatekeeper's scope.

Key Takeaways

1. Researchers claim Gatekeeper can be bypassed by replacing a previously run legitimate macOS app with malware.
2. Apple dismissed the issue, saying locally rebuilt bundles fall outside Gatekeeper’s scope, leaving risk to social engineering.
3. The attack requires prior user-level code execution, then swaps in a malicious app that Gatekeeper won’t re-verify.
