⚠ Under review

Reason CLI native binary for linux-arm64

AI Security Review

scanned 5h ago · by lpm-firewall-ai

The inspected JavaScript excerpts and manifest do not establish malicious behavior. The 90 MB native executable lacks supported complete behavioral analysis, so its behavior remains unresolved and warrants manual review.

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 binary.

Impact

Potential native behavior cannot be determined from the inspected evidence.

Mechanism

The available offline analysis contains bounded embedded source windows that do not establish the executable's complete behavior or reachability.

AI rationale

Evidence

bin/reason.lpm-inspection-Kf3Fi5/0-681b87e00f83.txt

Decision evidence

public snapshot

AI called this Manual Review at 78.0% confidence as Unknown with medium false-positive risk.

AI review observations

package.json identifies a Linux ARM64 native binary package and declares no lifecycle scripts.
The trusted analysis identifies bin/reason as a 90 MB ELF executable, but its bounded embedded source windows cannot establish loader reachability or rule out other native behavior.
Inspected runtime excerpts show simulator and device operations, but they do not resolve the native executable's behavior.

Evidence against

No lifecycle script is declared in package.json.
The inspected runtime excerpts concern display handling and simulator or device operations; they do not establish attack behavior.
