The Agent Skills Directory

[PRIVILEGE_ESCALATION]: The skill's primary function is to exploit a Linux kernel logic flaw (CVE-2026-31431) for local privilege escalation. It specifically targets the patching of the /usr/bin/su setuid binary to gain root access.
[EXTERNAL_DOWNLOADS]: The instructions direct the user to download pre-compiled exploit binaries from an unverified third-party GitHub repository (badsectorlabs/copyfail-go).
[REMOTE_CODE_EXECUTION]: The skill facilitates remote code execution by instructing the user to download, mark as executable (chmod +x), and run a binary from an untrusted source.
[COMMAND_EXECUTION]: The skill provides commands to modify system-level binaries and manipulate file metadata, such as using touch -r to restore the original modification time of a binary to evade detection.
[DYNAMIC_EXECUTION]: The skill includes instructions for installing build tools and compiling assembly shellcode payloads and the main Go exploit binary at runtime using nasm and goreleaser.
[PERSISTENCE]: The skill provides a 'Restore Script' and specific instructions to revert changes to the system binary after the exploit has succeeded, which is a tactic used to maintain a stealthy presence and avoid system breakage that would alert administrators.
