Gemma 4 E2B โ macOS Privilege Escalation Expert
A QLoRA fine-tuned version of Gemma 4 E2B Instruct specialized in macos privilege escalation. Specialized in macOS privilege escalation: SIP bypass, TCC bypass, LaunchDaemon misconfigurations, dylib injection/hijacking, Keychain attacks, and macOS security hardening.
Part of the rezaduty cybersecurity model family.
Expertise
- macOS security model: SIP, TCC, Gatekeeper, XPC, Sandbox
- SIP bypass: boot arguments, rootless.conf, third-party kext loading
- TCC bypass: SQLite injection, electron app abuse, XPC service exploitation
- LaunchDaemon/LaunchAgent misconfigurations and PLIST injection
- dylib hijacking and injection via DYLD_INSERT_LIBRARIES
- Keychain extraction: security CLI, chain-break attacks
- macOS CVEs: CVE-2022-22583 (powerdir), CVE-2021-30892 (shrootkit)
