AI Security Review
scanned 9d ago · by lpm-firewall-aiThe inspected JavaScript shows a conditional postinstall shim replacement and CLI forwarding, with no confirmed attack behavior. Material native binary behavior remains unresolved, requiring manual review.
Static reason
One or more suspicious static signals were detected.
Trigger
Installing the package triggers its postinstall hook; running the CLI invokes the platform binary.
Impact
The inspected installer behavior is limited to the package CLI, but unresolved native behavior prevents a reliable package-wide verdict.
Mechanism
The hook may replace the CLI shim with a native binary after a version check. Offline analysis could not inspect most binaries and left part of the Windows x64 call graph unreviewed.
AI rationale
The inspected JavaScript shows a conditional postinstall shim replacement and CLI forwarding, with no confirmed attack behavior. Material native binary behavior remains unresolved, requiring manual review.

Decision evidence
public snapshotAI called this Manual Review at 95.0% confidence as Unknown with medium false-positive risk.
AI review observations
- package.json runs install.js from a postinstall hook.
- install.js conditionally stages the platform binary and runs it with --version before replacing the CLI shim.
- bin/tm.js forwards CLI arguments to the platform binary.
- Offline analysis could not inspect several native binaries; the Windows x64 analysis also leaves call targets uninspected.
Evidence against
- The install hook exits on Windows and when the npm user agent check fails.
- The inspected JavaScript shows a CLI shim replacement and argument forwarding, but no confirmed attack behavior.
