ICOA CLI — The world's first CLI-native cyber & AI security olympiad terminal: AI4CTF (Day 1), CTF4AI (Day 2), VLA4CTF (Pioneer Round — embodied AI)

AI Security Review

scanned 6d ago · by lpm-firewall-ai

No confirmed malicious attack surface was established. Risky primitives are present, including obfuscated challenge modules, user-invoked shell execution, Docker/nc spawning, and ICOA API calls, but they match the advertised CTF CLI behavior and are not install-time or hidden exfiltration paths.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

Explicit user CLI actions such as icoa, ctf4ai, ctf4eai, connect, shell, or sandbox commands

Impact

No confirmed unauthorized credential theft, persistence, destructive behavior, or hidden payload execution

Mechanism

user-invoked CTF tooling and ICOA API communication

Rationale

Static inspection found suspicious-looking obfuscation and dual-use CTF primitives, but the reachable behaviors are user-invoked competition features and the install hook is only cosmetic output. No concrete unconsented execution, credential harvesting, exfiltration, persistence, or destructive action was found.

Decision evidence

public snapshot

AI called this Clean at 82.0% confidence as Benign with medium false-positive risk.

Evidence for block

dist/commands/ctf4ai-demo.js and dist/commands/ctf4vla.js are heavily obfuscated despite being CLI command modules.
dist/commands/ctf4ai-demo.js supports user-entered ! commands via execSync during an active CTF4AI session.
dist/lib/sandbox.js and dist/lib/interactive-spawn.js invoke docker/nc/ssh-style tools, but only from explicit CLI actions.

Evidence against

package.json postinstall only prints an install progress/banner and catches errors.
dist/index.js registers CLI commands; no import-time exfiltration or lifecycle attack observed.
dist/lib/tool-man.js is a static CTF tool cheatsheet; reverse-shell-like strings are netcat documentation examples.
dist/lib/gemini.js sends chat only to configured ICOA/CTFd server, defaulting to https://practice.icoa2026.au.
dist/lib/config.js stores config under ~/.icoa with chmod 0600 and does not harvest unrelated files.
Network and shell capabilities are package-aligned for a CTF competition CLI and user-triggered.
