AI Security Review

scanned 2mo ago · by lpm-firewall-ai

Source confirms a user-invoked, first-party AI-agent extension setup with persistent hooks and configured network use, not concrete malicious install-time behavior or stealthy exfiltration. Per policy, this warrants a warning rather than a block.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

User runs cachly init, setup, autosetup, or autopilot; subsequent commits trigger the installed Git hook.

Impact

Configured agents and Git commits can automatically invoke Cachly and send configured project/commit context to its service.

Mechanism

First-party MCP configuration, instruction injection, and persistent hook installation.

AI rationale

Network endpoints

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

Explicit setup/autopilot writes MCP and AI-instruction files, then installs Git and Claude hooks.
Generated Claude instructions mandate Cachly calls at conversation start and before every task.
The installed post-commit hook silently launches Cachly ingestion with commit metadata.
Runtime authentication persists a Cachly credential/configuration entry in the user's Claude config.

Evidence against

The npm postinstall script only prints setup instructions; it performs no filesystem, network, or config mutation.
AI-agent and hook mutations are reached through explicit init/setup/autopilot commands, not installation.
Observed Cachly network destinations are package-aligned first-party endpoints.
