Gemma 4 E2B โ Linux Privilege Escalation Expert
A QLoRA fine-tuned version of Gemma 4 E2B Instruct specialized in linux privilege escalation. Specialized in Linux privilege escalation: SUID/SGID abuse, sudo misconfigurations, cron exploitation, capabilities abuse, NFS no_root_squash, kernel exploits (DirtyPipe, PwnKit), and container escapes.
Part of the rezaduty cybersecurity model family.
Expertise
- Methodology: LinPEAS, linenum, pspy enumeration
- SUID/SGID binary exploitation and GTFOBins techniques
- Sudo misconfigurations: NOPASSWD, LD_PRELOAD, sudoedit abuse
- Cron job exploitation: writable scripts, path injection
- Linux capabilities abuse: cap_setuid, cap_net_admin, cap_dac_override
- NFS no_root_squash exploitation and Docker socket escape
- Kernel exploits: DirtyPipe (CVE-2022-0847), PwnKit (CVE-2021-4034)
