AI Security Review
scanned 5d ago · by lpm-firewall-aiThe package sends anonymous, limited install telemetry automatically from its postinstall hook, with telemetry enabled by default. The disclosure and opt-out reduce the risk, but install-time telemetry on by default is warning-worthy.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
npm postinstall, unless CI, DO_NOT_TRACK, or a prior telemetry disable setting blocks it.
Impact
Reports install and basic runtime/platform metadata tied to a random install ID without installer opt-in; this is a privacy risk, but the reviewed event flow does not show credential or project-data collection.
Mechanism
The hook records an install event and starts a detached child that flushes queued events to the package analytics host.
AI rationale
The package sends anonymous, limited install telemetry automatically from its postinstall hook, with telemetry enabled by default. The disclosure and opt-out reduce the risk, but install-time telemetry on by default is warning-worthy.

Decision evidence
public snapshotAI called this Suspicious at 97.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The package runs scripts/postinstall.mjs automatically after installation.
- The install hook records an install event and launches a detached telemetry flush.
- Telemetry is enabled by default when a published key is present; CI, DO_NOT_TRACK, and an explicit disable setting close the gate.
- The install event records the package version and whether the install was global, alongside common platform and runtime fields and a random install ID.
- The queued events are POSTed to the package's analytics host, events.nanonets.com.
- The README discloses anonymous usage stats and documents how to disable them.
Evidence against
- The telemetry contract filters event names and fields, and restricts values to fixed labels or buckets.
- The install event carries no hostname, username, project path, credential, or file contents.
- Telemetry is disclosed in the README and can be disabled with DO_NOT_TRACK=1 or the package's telemetry command.
- The public API entry point consists of exports and has no apparent import-time action.
