THREAT OF TCC BYPASSES ON MACOS

Summary from the TLDR InfoSec newsletter

macOS's TCC framework blocks unauthorized access to sensitive data, even for malware with root access, but many third-party apps expose vulnerabilities that bypass these protections. A flaw in Cursor.app shows how malware can inherit TCC permissions and access protected files without user knowledge. Developers and vendors often ignore these issues, despite their real threat to user privacy and system integrity.
