Reason CLI native binary for linux-arm64

AI Security Review

scanned 21h ago · by lpm-firewall-ai

The manifest has no lifecycle hook, but this package ships a large native executable whose behavior is not resolved by the available bounded analysis. Manual review is needed; scanner similarity labels alone do not establish malicious behavior.

Static reason

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

Trigger

Execution of bin/reason.

Impact

Potential behavior cannot be determined from the available analysis.

Mechanism

The available offline analysis contains only bounded embedded-source windows and does not resolve the executable’s behavior.

AI rationale

Evidence

.lpm-inspection-nomKnJ/0-d125fa285450.txtbin/reason

Decision evidence

public snapshot

AI called this Manual Review at 84.0% confidence as Unknown with medium false-positive risk.

AI review observations

package.json identifies this as a Linux ARM64 native-binary package and shows no lifecycle scripts or JavaScript entrypoint in the inspected manifest.
The offline analysis identifies bin/reason as a 90,425,640-byte ELF and says its bounded embedded-source windows cannot establish loader reachability or rule out other native behavior.

Evidence against

The inspected package manifest shows no install-time lifecycle hook; the available evidence does not establish a concrete attack.
