AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe verified install-time chain performs unconsented hosts-file/DNS mutation and drops launch artifacts. This is concrete harmful behavior, not merely a user-invoked installer.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
npm postinstall inside a DSH profile
Impact
Can redirect GitHub traffic and add persistent user launch artifacts.
Mechanism
detached launcher invokes PowerShell to alter hosts mappings and create shortcuts
Attack narrative
The postinstall hook starts the bundled launcher without user action. Its default launch path synchronously invokes install.ps1 with PowerShell execution-policy bypass; that script calls Ensure-GitHubReachable before handling ShortcutOnly, attempting to rewrite the Windows hosts file for GitHub domains and flush DNS. It also creates a hidden VBS launcher and Desktop/Start Menu shortcuts.

Decision evidence
public snapshotAI called this Malicious at 97.0% confidence as Malware with low false-positive risk.
Evidence for block
- postinstall launches a detached desktop launcher in DSH profiles.
- Launcher runs PowerShell with ExecutionPolicy Bypass during that install path.
- The invoked script modifies the Windows hosts file and flushes DNS.
- GitHub host mappings run before the ShortcutOnly branch.
- The script writes a VBS launcher and Desktop/Start Menu shortcuts.
Evidence against
- No credential harvesting or data exfiltration was found.
- Network logic otherwise targets localhost or user-configured update URLs.
