Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Domain fronting and CDN abuse for C2 concealment — CloudFront, Azure CDN, Fastly setup, TLS SNI vs Host header technique, CDN-based redirectors, and integration with Cobalt Strike and Sliver.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'c2-domain-fronting' ] || [ -L ~/.agents/skills/'c2-domain-fronting' ]; then echo 'A skill folder named c2-domain-fronting already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/BitterSecurity/Decepticon' "$d" && git -C "$d" checkout --quiet 'bdb1016c93ed687f61ac57481da298c25a47c8f5' -- 'packages/decepticon/decepticon/skills/standard/post-exploit/c2-domain-fronting' && mkdir -p ~/.agents/skills && cp -R "$d"/'packages/decepticon/decepticon/skills/standard/post-exploit/c2-domain-fronting' ~/.agents/skills/'c2-domain-fronting' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'c2-domain-fronting' ~/.claude/skills/'c2-domain-fronting' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
