Reason CLI native binary for linux-arm64

AI Security Review

scanned 5h ago · by lpm-firewall-ai

The manifest and inspected JavaScript did not establish an attack. The required native executable analysis is materially limited, so its behavior cannot be cleared by static source inspection.

Static reason

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

Trigger

Running the packaged native CLI executable.

Impact

Potential behavior of the executable cannot be determined from the available source evidence.

Mechanism

The executable is an ELF binary containing embedded source candidates, but the inspected analysis does not establish their reachability or cover all native behavior.

AI rationale

The manifest and inspected JavaScript did not establish an attack. The required native executable analysis is materially limited, so its behavior cannot be cleared by static source inspection.

Evidence

bin/reason.lpm-inspection-qQ7d0h/0-79a6ea36b146.txt

Decision evidence

public snapshot

AI called this Manual Review at 64.0% confidence as Unknown with medium false-positive risk.

AI review observations

package.json identifies this as a Linux ARM64 CLI binary package and declares no lifecycle scripts.
Offline analysis identifies bin/reason as a 90 MB ELF executable but covers only bounded embedded source windows; it cannot establish loader reachability or rule out other native behavior.
The inspected JavaScript snippets expose simulator and process-control functionality but do not establish malicious behavior.
