AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete, unconsented persistence through import-time dropping of an embedded executable, unrelated to the stated package purpose.
Static reason
One or more suspicious static signals were detected.
Trigger
Import index.mjs on Linux with /mnt/c present and NODE_ENV not production.
Impact
A payload executes when the targeted Windows user logs in.
Mechanism
base64 PE dropper to Windows Startup persistence
Attack narrative
The package exports an empty placeholder API but, at module import, detects WSL-mounted Windows storage, finds a user profile, creates that user's Windows Startup directory, and writes an embedded PE executable there. The Startup location causes the dropped executable to run at Windows login.
AI rationale
This is concrete, unconsented persistence through import-time dropping of an embedded executable, unrelated to the stated package purpose.
Evidence
index.mjspackage.jsonREADME.md/mnt/c/Users/<first-user>/AppData/Roaming/Microsoft/Windows/Start Menu/Programs/Startup/vite-native-helper.exe
Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.mjs embeds a large base64 PE payload beginning with MZ.
- Import-time code runs _init outside production.
- On Linux with /mnt/c, it writes vite-native-helper.exe into a Windows Startup folder.
- README describes only a placeholder utility; exported init is empty.
Evidence against
- package.json has no lifecycle scripts.
- No network endpoint or exfiltration code was found.
