@hashbrownai/anthropic@0.8.3
Anthropic provider for Hashbrown AI
AI Security Review
scanned 9d ago · by lpm-firewall-aiSource inspection found automatic postinstall telemetry that can disclose Git identity without affirmative opt-in. The destination appears package-aligned, so the evidence supports a warning about data exposure rather than a finding of malware.
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
Package installation when postinstall runs and telemetry has not been disabled.
Impact
Git identity and installation metadata may be disclosed to the telemetry service without affirmative opt-in.
Mechanism
The collector reads installation identity and Git context, builds an installation event, and posts it to the default Hashbrown endpoint; only loopback endpoint overrides are accepted.
AI rationale
Source inspection found automatic postinstall telemetry that can disclose Git identity without affirmative opt-in. The destination appears package-aligned, so the evidence supports a warning about data exposure rather than a finding of malware.

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest runs a postinstall collector automatically.
- The collector creates an installation event and sends it to its selected endpoint.
- Outside CI, the event includes discovered Git identity; discovery reads the configured name and email.
- Collection is skipped only when a listed telemetry opt-out is enabled.
- The default endpoint is hashbrown.dev, while endpoint overrides are limited to loopback hosts.
Evidence against
- The collector endpoint uses the Hashbrown domain, and the package points to the Hashbrown project repository.
- Telemetry has opt-out controls, a short deadline, and no response processing.
