AI Security Review
scanned 13d ago · by lpm-firewall-aiSource inspection confirms an install hook that patches pi and startup code that writes extensions into pi's shared agent directory. This fits the warning-only category for first-party agent extension setup; the inspected credential path does not establish exfiltration.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
Package installation triggers the patch script; running the CLI initializes the agent and writes extensions.
Impact
The extensions are loaded through pi's shared extension mechanism and can affect its TUI and desktop clients.
Mechanism
The postinstall script patches pi dependencies, while the CLI creates named u1s1 extensions under pi's agent directory.
AI rationale
Source inspection confirms an install hook that patches pi and startup code that writes extensions into pi's shared agent directory. This fits the warning-only category for first-party agent extension setup; the inspected credential path does not establish exfiltration.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs a postinstall patch script.
- The CLI initializes pi on startup and sets its agent directory.
- The package writes its tools extension into pi's shared extensions directory.
Evidence against
- The signing proxy binds to loopback and checks a generated bearer key before forwarding requests to the configured service origin.
- The child environment guard is designed to keep API credentials out of subprocesses.
