ctf-pwn
Provides binary exploitation techniques for CTF challenges. Use when you already have a vulnerable native target or service and need to turn memory corruption or low-level primitives into code execution or privilege escalation, such as buffer overflows, format strings, heap bugs, ROP, ret2libc, shellcode, kernel exploitation, seccomp bypass, sandbox escape, or Windows/Linux exploit chains. Do not use it when the main blocker is understanding what the binary does; use reverse engineering first. Do not use it for pure web bugs, disk or packet forensics, or standalone crypto/math challenges.

E006: Malicious code pattern detected in skill scripts.
What this means
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
Why it was flagged
The content contains explicit, repeatable instructions to achieve remote code execution, spawn reverse/interactive shells, and exfiltrate data to attacker-controlled servers (including use of Meterpreter/netcat and JavaScript fetch exfil), which are high-risk dual‑use techniques that can be abused as backdoors and for unauthorized data theft.
W013: Attempt to modify system services in skill instructions.
What this means
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
Why it was flagged
The skill explicitly documents kernel privilege-escalation and sandbox-escape techniques (e.g., modprobe_path/core_pattern overwrite, seccomp/KPTI bypass, emulator eval injection) which teach bypassing security mechanisms and modifying system state, so it could push an agent to compromise the host.
