thalamus@1.5.84
⚠ Under reviewMobile and Web client for Claude Code
AI Security Review
scanned 19d ago · by lpm-firewall-aiThe inspected source does not establish malicious behavior, and the telemetry excerpts show encrypted host hardware samples sent to the configured Thalamus server. The shipped executable archive remains materially unresolved, so manual review is appropriate.
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
Package installation triggers the postinstall unpacker.
Impact
The archive's behavior cannot be determined from the inspected evidence, so a clean verdict is not supported.
Mechanism
The unpacker selects platform-specific binaries from compressed archives; the relevant archive could not be structurally inspected within the available budget.
AI rationale
The inspected source does not establish malicious behavior, and the telemetry excerpts show encrypted host hardware samples sent to the configured Thalamus server. The shipped executable archive remains materially unresolved, so manual review is appropriate.
Evidence

Decision evidence
public snapshotAI called this Manual Review at 72.0% confidence as Unknown with medium false-positive risk.
AI review observations
- The postinstall hook runs a platform tool unpacker, and that unpacker describes its purpose as extracting platform binaries.
- The shipped archive is a gzip file whose expanded contents exceeded the available structural inspection budget, leaving its contents unresolved.
- The inspected telemetry code sends encrypted host hardware samples to the configured Thalamus server.
Evidence against
- The flagged Claude project paths are used to read transcripts and write friction metrics; those excerpts do not show agent configuration changes.
