@hashbrownai/ollama@0.8.3
Ollama provider for Hashbrown AI
AI Security Review
scanned 6d ago · by lpm-firewall-aiThe automatic postinstall hook sends configured Git display names and email addresses to the package vendor’s collection endpoint without explicit consent. Because this collects personal details from the user's machine during installation, classify it as data exfiltration.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
Automatic package installation when the postinstall lifecycle runs.
Impact
Exposes personal identity details to the package vendor without the installer's explicit consent.
Mechanism
Reads Git configuration, attaches the configured display name and email to the event outside CI, and posts it to the default collection endpoint. Opt-out environment variables are available, but consent is not requested.
Attack narrative
During installation, the postinstall hook gathers Git identity information and, outside CI, includes the configured display name and email in an install event sent to hashbrown.dev. The hook runs automatically without an explicit consent prompt; opt-out variables do not change the default collection behavior.
AI rationale
The automatic postinstall hook sends configured Git display names and email addresses to the package vendor’s collection endpoint without explicit consent. Because this collects personal details from the user's machine during installation, classify it as data exfiltration.

Decision evidence
public snapshotAI called this Malicious at 97.0% confidence as Malware with low false-positive risk.
Evidence for block
- The package runs a postinstall hook automatically.
- The install collector reads Git identity data, including the configured display name and email.
- Outside CI, the collector attaches that identity to the install event and sends the batch.
- The batch is sent to the package vendor’s install collection endpoint without an explicit consent prompt.
Evidence against
- The collector honors several telemetry opt-out environment variables.
- The runtime entry point exports the Ollama adapter; the flagged collection is in the install hook.
