Mission control for AI coding agents - run 20 autonomous agents with real-time monitoring and session persistence

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The package has concrete unconsented install-time persistence-like behavior, but the inspected source does not meet the policy threshold for a malicious publish block. Its lifecycle hook mutates a consumer repository and launches a detached process.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

Installing the package with npm runs the postinstall lifecycle hook.

Impact

It can replace repository commit behavior and leave a package-controlled process running after installation.

Mechanism

Postinstall hook overwrite and detached server launch.

AI rationale

Evidence

package.jsonscripts/postinstall.js.git/hooks/pre-commitdist/index.js

Network endpoints1

127.0.0.1

Decision evidence

public snapshot

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

Evidence for warning

The package runs scripts/postinstall.js automatically after installation.
The postinstall script overwrites the consumer repository's pre-commit hook.
The postinstall script starts a detached web server unless an opt-out variable is set.

Evidence against

No runtime dependency on aicodeman itself is declared.
The inspected automatic server binds to localhost and no secret exfiltration was confirmed.
Claude credential access is limited to an opt-in voice feature with origin checks.
