AI Security Review

scanned 2mo ago · by lpm-firewall-ai

No malicious install-time or covert exfiltration chain is present, but the explicit activation path is a remote code delivery mechanism whose payload is absent from the tarball and not independently authenticated in the inspected source.

Static reason

No blocking static signals were detected.; previous stored version diff introduced dangerous source

Trigger

User runs activate via CLI/MCP, install-claude-hook, or install-autostart.

Impact

A compromised activation service could execute arbitrary delta code after user activation.

Mechanism

Remote encrypted delta loading and explicit local agent/persistence setup.

AI rationale

Decision evidence

public snapshot

AI called this Suspicious at 93.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

Activation fetches an encrypted remote delta from api.compr.ch.
The delta is decrypted, written as .mjs files, then dynamically imported.
Claude hook and LaunchAgent installers can persist behavior, but only through explicit CLI commands.

Evidence against

package.json has no preinstall, install, or postinstall hook.
The hook posts to a loopback endpoint, not an external collector.
No shipped source shows credential harvesting or external data exfiltration.
