AI Security Review
scanned 11d ago · by lpm-firewall-aiThe inspected JavaScript shows package-aligned host telemetry sent to the configured Thalamus service, not a verified attack. The postinstall-extracted executable archive could not be inspected, so its behavior remains unresolved.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
Package installation runs the postinstall hook.
Impact
The extracted binary’s behavior remains unresolved, so this review cannot rule out harmful behavior in it.
Mechanism
The hook invokes a local script that extracts platform-specific tool archives into the package directory.
AI rationale
The inspected JavaScript shows package-aligned host telemetry sent to the configured Thalamus service, not a verified attack. The postinstall-extracted executable archive could not be inspected, so its behavior remains unresolved.
Evidence
package.jsonscripts/unpack-tools.cjstools/archives/difftastic-arm64-linux.tar.gz
Decision evidence
public snapshotAI called this Manual Review at 71.0% confidence as Unknown with medium false-positive risk.
AI review observations
- The postinstall hook runs the package’s local tool unpacker.
- The unpacker selects and extracts a platform-specific Difftastic archive.
- Daemon startup launches host telemetry for served organizations.
- Telemetry contains host RAM metrics and is encrypted with an organization key before sending to the configured server.
- The default server is the package’s Thalamus service.
Evidence against
- The inspected telemetry path sends host metrics to the configured Thalamus service; it does not establish credential theft or an unrelated recipient.
- The platform archive is an executable binary whose behavior could not be resolved from the available inspection.
