Anthropic provider for Hashbrown AI
AI Security Review
scanned 9d ago · by lpm-firewall-aiStatic source inspection confirms automatic installation telemetry can include Git identity and is sent to the publisher's endpoint without affirmative opt-in. The publisher-aligned recipient and opt-out controls reduce the risk, and the source does not establish credential theft or another concrete attack.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
Installing the package with lifecycle scripts enabled, unless a telemetry opt-out is set.
Impact
Git identity and install metadata are disclosed to the telemetry service without an affirmative opt-in.
Mechanism
The hook gathers installation and Git configuration details and posts the resulting event to the Hashbrown telemetry endpoint.
AI rationale
Static source inspection confirms automatic installation telemetry can include Git identity and is sent to the publisher's endpoint without affirmative opt-in. The publisher-aligned recipient and opt-out controls reduce the risk, and the source does not establish credential theft or another concrete attack.

Decision evidence
public snapshotAI called this Suspicious at 89.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package runs an install collector automatically from its postinstall hook.
- The collector sends install events to a fixed Hashbrown telemetry endpoint and includes discovered Git identity in the event.
- Git discovery reads global and checkout configuration and can add the user's Git display name and email to the event.
- Collection is automatic unless a telemetry opt-out is set; the source does not require affirmative consent.
Evidence against
- The recipient is the package publisher's Hashbrown telemetry endpoint, and the collector provides opt-out controls.
- The collector sends package and environment metadata for an install event; the source does not establish credential collection or a separate malicious action.
