⚠ Under reviewReason CLI native binary for win32-x64
AI Security Review
scanned 1d ago · by lpm-firewall-aiThe package manifest identifies a platform-specific native CLI, and the flagged JavaScript contains sandbox-helper support. The native executable’s bounded analysis leaves material behavior unresolved, so a malicious verdict is not supported and manual review is warranted.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
The local-login worker feature; the extracted CLI help describes it as enabled by default.
Impact
The native executable remains partially unresolved, so its complete behavior cannot be determined from this analysis.
Mechanism
Extracted code reads local authentication material and passes access-token records to a subscription call when local-login configuration is enabled.
AI rationale
The package manifest identifies a platform-specific native CLI, and the flagged JavaScript contains sandbox-helper support. The native executable’s bounded analysis leaves material behavior unresolved, so a malicious verdict is not supported and manual review is warranted.

Decision evidence
public snapshotAI called this Manual Review at 91.0% confidence as Unknown with medium false-positive risk.
AI review observations
- The manifest identifies a Windows x64 CLI distribution.
- The flagged JavaScript refers to the packaged sandbox executable.
- The trusted offline analysis says its bounded source windows cannot establish loader reachability or rule out other native behavior.
- Embedded source includes code that reads local authentication material and passes access-token records to a subscription call; the shown worker caller gates this on local-login configuration, which the CLI help says is on by default.
Evidence against
- The inspected excerpts do not establish credential transfer to an unrelated recipient or prove that the extracted code is reachable.
- The flagged JavaScript excerpt is consistent with dispatching a packaged sandbox helper.
