@hashbrownai/anthropic@0.8.0
Anthropic provider for Hashbrown AI
AI Security Review
scanned 13d ago · by lpm-firewall-aiSource confirms an automatic installation beacon that can disclose persistent identifiers and personal Git details without affirmative consent. The recipient is package-aligned and the source provides opt-outs, so the evidence supports a warning rather than a publication block.
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
The package manager runs the postinstall hook.
Impact
The package publisher receives installation and potentially personal Git identity information without an affirmative consent step.
Mechanism
The collector sends an installation event with a persistent per-user identifier and environment data; outside CI it can include Git identity and repository context. Collection is enabled by default, with opt-out variables available.
AI rationale
Source confirms an automatic installation beacon that can disclose persistent identifiers and personal Git details without affirmative consent. The recipient is package-aligned and the source provides opt-outs, so the evidence supports a warning rather than a publication block.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest runs a postinstall hook, which invokes the collector during package installation.
- The collector builds an installation event with package, platform, runtime, package-manager, environment, and checkout context details.
- Outside CI, the event may include the configured Git display name and email; it is sent to a fixed Hashbrown collection endpoint.
- The collector sends by default unless an opt-out variable is set; endpoint overrides are limited to loopback hosts.
Evidence against
- The collection endpoint is on the Hashbrown domain and accepts installation telemetry for Hashbrown packages.
- Several telemetry opt-out variables are supported, and the collector does not follow redirects or use the response to configure behavior.
