Reason CLI native binary for linux-arm64

AI Security Review

scanned 1d ago · by lpm-firewall-ai

The manifest has no install hook, and the inspected JavaScript hints do not establish an attack. The 90 MB native executable is the package’s core artifact, and its limited analysis cannot resolve its behavior, so manual review is warranted.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

Execution of the packaged native CLI.

Impact

Potential behavior of the executable cannot be determined from the available analysis.

Mechanism

The available offline analysis shows bounded embedded-source candidates but does not establish which code is reachable or characterize all native behavior.

AI rationale

Evidence

bin/reason.lpm-inspection-tJuLFq/0-82a952246b6b.txt

Decision evidence

public snapshot

AI called this Manual Review at 91.0% confidence as Unknown with medium false-positive risk.

AI review observations

package.json identifies this as a Linux ARM64 native-binary package; it has no install lifecycle hook.
The native executable is the package’s central artifact, but its offline analysis contains only bounded embedded-source candidates and explicitly cannot establish loader reachability or rule out other native behavior.

Evidence against

The inspected manifest contains no lifecycle scripts, so no install-time attack trigger was identified.
