AI Security Review
scanned 3d ago · by lpm-firewall-aiThe scanner's credential-exfiltration lead is explained by an interactive TSCircuit registry login flow, with no evidence of credentials sent to an unrelated receiver. However, the browser bundle initializes PostHog automatically and sends usage telemetry with the embedding domain or anonymous ID; under the review rules, undisclosed runtime telemetry warrants a warning.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Importing the browser bundle initializes PostHog; rendering RunFrame captures activity events.
Impact
The embedding domain and usage activity are disclosed to the telemetry service without an explicit consent prompt.
Mechanism
PostHog receives RunFrame usage properties, embedding-domain identity, and an anonymous ID. A window flag can disable telemetry.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The browser bundle initializes PostHog at module load and sends telemetry to https://postpig.tscircuit.com; telemetry can be disabled with a window flag.
- RunFrame activity events include the embedding domain and an anonymous ID, along with component usage properties.
- Registry login is initiated by a Sign In flow that opens a browser authentication page; the returned session token is stored for registry use.
- The package exports browser UI entry points and declares no install lifecycle scripts.
Evidence against
- The credential flow uses the TSCircuit registry login-page exchange and does not show credentials being sent to an unrelated host.
- The telemetry code uses an anonymous identifier or embedding domain rather than showing collection of credentials or file contents.
