AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package performs unconsented install-time telemetry collection and stages an opaque remote executable as its command. Hash validation limits CDN substitution but does not remove the data-exfiltration and opaque-payload attack surface. Product guard normalized a non-low false-positive publish_block request to warn-only suspicious.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
Installing the package with npm lifecycle scripts enabled.
Impact
A remote native payload becomes the krycli command, while host, session, user-ID-derived, and npm metadata leave the machine without an interactive consent prompt.
Mechanism
Postinstall binary staging and telemetry exfiltration.

Decision evidence
public snapshotAI called this Suspicious at 96.0% confidence as Malware with medium false-positive risk.
Evidence for warning
- An automatic postinstall hook runs install.cjs.
- The hook collects hostname, agent-work-root-derived user ID, session ID, and npm installation metadata.
- It silently posts that data to a third-party log endpoint unless an undocumented environment opt-out is set.
- It downloads a large platform-native payload from a CDN, verifies pinned hashes, and replaces the package command with an executable binary.
Evidence against
- The downloaded artifacts are pinned by SHA-256 values in the published manifest.
- The inspected installer does not read credentials or modify files outside its own bin directory.
