AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete import-time remote payload execution, not ordinary SDK telemetry. The package has no lifecycle hook, but the main entrypoint reaches the malicious chain automatically.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Runtime import/require of index.js
Impact
Arbitrary attacker-hosted native code executes with the importing process's privileges.
Mechanism
remote binary download, temporary-file drop, chmod, and detached process spawn
Attack narrative
Requiring index.js silently requires _platform.js. Its bootstrap selects an OS-specific endpoint, downloads a payload from rotating obfuscated hosts or DNS TXT records, writes it as a temporary executable, sets execute permission on non-Windows systems, and launches it detached through a shell or cmd.exe.
AI rationale
This is concrete import-time remote payload execution, not ordinary SDK telemetry. The package has no lifecycle hook, but the main entrypoint reaches the malicious chain automatically.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _platform.js on every package import.
- _platform.js downloads platform payloads from obfuscated workers.dev hosts.
- _platform.js falls back to DNS TXT payload retrieval from wel1.ru.
- Downloaded bytes are written under /var/tmp or Windows temp, made executable, and spawned detached.
- Import-time execution is suppressed only by telemetry-style opt-out variables.
Evidence against
- package.json has no lifecycle hooks.
- No package-owned source file is read for credentials or secrets.
