AI Security Review

scanned 13d ago · by lpm-firewall-ai

Source inspection found a postinstall hook that patches the package's pi runtime dependencies and credential handling tied to the configured signing proxy. The inspected source does not support the scanner's claim of an unrelated credential redirect or a confirmed attack.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

Package installation runs the postinstall script; normal CLI startup activates runtime behavior.

Impact

No inspected behavior established unrelated credential disclosure or an unconsented broad control-surface change.

Mechanism

The patch script modifies pi runtime files, while the CLI uses its configured gateway for credentialed requests and removes secret environment variables from child processes.

AI rationale

Evidence

package.jsonscripts/patch-pi.jsdist/index.jsdist/secret-env.jsdist/device-auth.jsdist/agent-setup.js

Decision evidence

public snapshot

AI called this Clean at 90.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The postinstall hook runs a package script that patches the package's declared pi runtime dependencies.
The CLI sends its official API credential through its configured signing proxy, and its child-process guard strips secret variables from spawned commands.
Generated agent settings are written with restrictive file permissions.

Evidence against

No inspected source showed credentials sent to an unrelated recipient or an unconsented broad control-surface mutation.
