AI Security Review

scanned 2h ago · by lpm-firewall-ai

User-launched CTF modes load obfuscated modules that invoke Gemini, fetch package-aligned competition resources, and may spawn local tools/viewers. The install hook only prints a progress animation; no confirmed install-time attack surface exists.

Static reason

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

Trigger

User runs icoa and enters ctf4ai or ctf4eai modes.

Impact

User-triggered execution can access configured Gemini credentials and launch local helper processes; obfuscation prevents a clean safety determination.

Mechanism

Obfuscated interactive CTF workflow with dynamic child-process use and remote challenge retrieval.

Rationale

No concrete malicious install-time or stealth attack chain was confirmed, so a block is not justified. Obfuscated runtime code with dynamic process execution and remote challenge handling warrants a warning.

Evidence

Decision evidence

public snapshot

AI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

dist/commands/ctf4ai-demo.js is heavily obfuscated and dynamically imports child_process.
dist/commands/ctf4vla.js is heavily obfuscated, fetches challenge content, writes it, and spawns a local viewer.
dist/commands/ctf4ai-demo.js creates a Gemini chat session for an interactive CTF prompt-injection exercise.
dist/lib/config.js persists CLI state under ~/.icoa.
dist/index.js imports the obfuscated CTF modules at CLI startup.

Evidence against

package.json postinstall only loads dist/postinstall.js.
dist/postinstall.js only renders installation progress to stdout.
No preinstall hook or observed lifecycle network, shell, file, or agent-config mutation.
dist/lib/tool-man.js contains command-reference text; no socket or process implementation.
No .ssh, .npmrc, AI-agent configuration, credential harvesting, or exfiltration path was found.
