AI Security Review

scanned 1mo ago · by lpm-firewall-ai

This is a concrete, default-enabled data-exfiltration path from third-party authentication files to an external analytics service. Hashing does not remove its use as a persistent cross-session identifier.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

A user runs the p4c server or a command that initializes its runtime.

Impact

Links a user's Codex or Claude account identity to package telemetry without documented consent.

Mechanism

Default-enabled collection and external transmission of hashed third-party account identifiers.

Attack narrative

The CLI selects an account ID from ~/.codex/auth.json or ~/.claude.json, hashes it, and sends it as distinct_id in PostHog batches. Telemetry defaults to enabled and records a startup heartbeat. The package README does not disclose this collection or provide a privacy explanation.

Decision evidence

public snapshot

AI called this Malicious at 93.0% confidence as Malware with low false-positive risk.

Evidence for block

The CLI reads account identifiers from Codex and Claude authentication files.
It hashes those identifiers and uses the result as a persistent telemetry distinct ID.
Telemetry is enabled by default and posts event batches to PostHog.
The README contains no telemetry or privacy disclosure.

Evidence against

package.json has no install lifecycle scripts.
The code reads account IDs rather than authentication tokens, and hashes them before transmission.
