Microsoft discovered a macOS vulnerability in July this year that could bypass the Gatekeeper security mechanism to execute malware. After receiving the report from Microsoft, Apple fixed the vulnerability in macOS 13 (Ventura), macOS 12.6.2 (Monterey) and macOS 11.7.2 (Big Sur) updates released on the 13th of this month.
Microsoft called the discovered macOS vulnerability “Achilles” and notified it to Apple through “Coordinated Vulnerability Disclosure”. The vulnerability allows attackers to bypass Apple’s Gatekeeper security mechanism and plant arbitrary malware on Mac devices.
Microsoft detailed how the vulnerability was discovered and the implications of such issues in a recent article. These details are useful to security experts and researchers. “Gatekeeper plays an important role in stopping macOS malware, but it’s not completely secure,” Microsoft said in a blog post.
