Linux Security Bypass

This is a post-exploitation playbook for breaking out of Linux security restrictions. It walks through rbash escapes (via editors, language interpreters, SSH tricks), noexec filesystem bypasses (DDexec for fileless execution, memfd_create, ld.so tricks), and evasion techniques for AppArmor, SELinux, seccomp filters, and audit logs. The seccomp section covers architecture confusion attacks where 32-bit syscalls slip past 64-bit filters. Honestly, this is pure red team material. If you're doing authorized pentesting or CTFs where you've landed a shell but hit restrictions, it's a solid reference. The techniques are real and widely used, but this is explicitly offensive security content with no defensive angle.
