AI Security Review
scanned 6d ago · by lpm-firewall-aiThe runtime updater launches an opaque script automatically when the launcher starts, leaving meaningful execution risk unresolved. The inspected source does not prove malicious behavior, so this warrants a warning rather than a publish block.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user launches the agent through the launcher.
Impact
The child process can execute further code, but its effects are unresolved from the inspected source.
Mechanism
The launcher checks for a newer version and passes an embedded script to a child Node process; obfuscation prevents verifying that script’s behavior.
AI rationale
The runtime updater launches an opaque script automatically when the launcher starts, leaving meaningful execution risk unresolved. The inspected source does not prove malicious behavior, so this warrants a warning rather than a publish block.
Evidence
dist/launcher.js
Decision evidence
public snapshotAI called this Suspicious at 78.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- On launcher startup, the package checks for an update and starts a detached Node process with an embedded script; that script’s behavior is obscured.
- The publish script runs an obfuscator, and the shipped launcher contains encoded strings decoded at runtime, limiting verification of the update script.
- The manifest defines prepublishOnly but no preinstall, install, or postinstall hook.
Evidence against
- The updater runs when the launcher is invoked, rather than through an install hook.
- The inspected source does not establish that the embedded script downloads or executes a malicious payload.
