⚠ Under review

Reason CLI native binary for linux-x64

AI Security Review

scanned 4d ago · by lpm-firewall-ai

The inspected JavaScript suggests credential handover is an opt-in product feature, and no attack was confirmed. The package's native executable remains materially unresolved, so manual review is appropriate.

Static reason

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

Trigger

Running the packaged CLI executable.

Impact

The executable's behavior cannot be assessed from the available analysis, so a clean verdict is not supported.

Mechanism

The available analysis contains bounded embedded-source candidates but does not establish their reachability or the executable's full behavior.

AI rationale

Evidence

.lpm-inspection-OoWF4C/0-75ff92b63223.txtbin/reason

Decision evidence

public snapshot

AI called this Manual Review at 94.0% confidence as Unknown with medium false-positive risk.

AI review observations

The manifest identifies this package as a Linux x64 native binary package and declares no lifecycle hooks.
The offline analysis identifies bin/reason as a 103 MB ELF Bun executable, but its bounded embedded-source windows cannot establish loader reachability or rule out other native behavior.
The inspected runtime reads local agent credentials only when localLogins is true and submits them through the service's localSubscription API; the available callers show that option being enabled for a user-started connection.

Evidence against

The inspected JavaScript paths show no confirmed credential theft or other attack; the credential handover appears tied to the product's local-login feature.
