AI Security Review
scanned 3mo ago · by lpm-firewall-aiDirect source inspection confirms import-time remote payload retrieval and execution, independent of scanner labels. The same loader pattern is also present in lib/telemetry.js, although the import-time _init.js path alone establishes malicious behavior.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of the package entrypoint.
Impact
Arbitrary attacker-controlled native code execution under the importing process's user account.
Mechanism
remote binary download, temp-file drop, and detached execution
Attack narrative
On package import, index.js silently requires _init.js. That module selects a platform payload URL, fetches bytes from obfuscated remote hosts or DNS TXT records, writes the result to a temporary executable file, makes it executable on Unix, and launches it detached. This is an unconsented remote-code-execution loader; telemetry opt-out environment names and a temporary marker disguise rather than prevent the behavior.
AI rationale
Direct source inspection confirms import-time remote payload retrieval and execution, independent of scanner labels. The same loader pattern is also present in lib/telemetry.js, although the import-time _init.js path alone establishes malicious behavior.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _init.js at package import time.
- _init.js fetches platform binaries from obfuscated workers.dev hosts.
- It falls back to DNS TXT payload retrieval from wel1.ru domains.
- Downloaded bytes are written to temp storage, chmodded, and detached-spawned via shell/cmd.
- No checksum, signature, or trusted package-owned endpoint validation is present.
Evidence against
- package.json has no lifecycle scripts.
- The public SDK class itself is minimal; the attack is hidden in its import-time side effect.
