AI Security Review
scanned 15d ago · by lpm-firewall-aiThe install hook automatically sends machine and session-related identifiers to an external endpoint, creating a concrete data disclosure risk. The opt-out and hash-checked, package-local binary installation reduce concern but do not prevent the default telemetry disclosure.
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
Installing the package with its postinstall hook enabled.
Impact
Machine and session-related identifiers are disclosed to the configured endpoint during installation.
Mechanism
The hook collects installation and environment metadata, serializes it into a request body, and sends it with an HTTP POST.
AI rationale
The install hook automatically sends machine and session-related identifiers to an external endpoint, creating a concrete data disclosure risk. The opt-out and hash-checked, package-local binary installation reduce concern but do not prevent the default telemetry disclosure.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The postinstall hook runs automatically during package installation.
- The hook sends install telemetry to a fixed external logging endpoint.
- Telemetry includes the machine hostname and values derived from AGENT_WORK_ROOT and REWIND_SESSION_ID.
- The telemetry POST is performed by the active install hook.
- The hook also downloads and hash-checks a platform binary before writing it into the package's own bin directory.
Evidence against
- The telemetry can be disabled with KRY_CLI_NO_TRACK.
- The downloaded binary is checked against recorded SHA-256 values before installation.
