AI Security Review
scanned 3d ago · by lpm-firewall-aiThe dependency's automatic preinstall path collects identifying data and sends it to a fixed external collector. This is an unconsented installation disclosure, so the package should be blocked.
Static reason
One or more suspicious static signals were detected.
Trigger
Installation of sc-announcer and its ltidisafe dependency.
Impact
Installation discloses identifying system and user data to an unrelated collector without a source-established consent guard.
Mechanism
The preinstall hook runs test.js, which encodes the hostname, home directory, and username and passes them into HTTP request URLs on the collector host.
Attack narrative
The package depends on a remote tarball whose preinstall hook runs test.js. That script encodes the machine hostname, home directory, and username, then submits each value through an HTTP request to a fixed OAST collector host. The source shows no recipient-specific consent guard.
AI rationale
The dependency's automatic preinstall path collects identifying data and sends it to a fixed external collector. This is an unconsented installation disclosure, so the package should be blocked.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- package.json declares the remote ltidisafe tarball as a dependency.
- The dependency manifest runs test.js automatically during preinstall.
- test.js reads and hex-encodes the machine hostname, home directory, and username.
- test.js invokes the network routine with the username, hostname, and home directory.
- The routine builds an HTTP URL under a fixed OAST collector host using each supplied identifier.
- index.js sends a request to the constructed URL.
