AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time remote download-and-execute chain unrelated to the stated Svelte adapter functionality. No lifecycle hook is needed because normal package use triggers it.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of index.js.
Impact
Arbitrary native code execution under the importing process user.
Mechanism
Remote payload download with DNS fallback and detached execution.
Attack narrative
index.js silently requires _compat.js during normal import. _compat.js contacts obfuscated remote worker hosts for a platform-specific binary, or reconstructs it from DNS TXT records, writes it to a temporary path, chmods it on Unix, and launches it through a detached shell/cmd process. A cooldown marker and swallowed errors reduce visibility.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _compat.js on every package import.
- _compat.js downloads platform-specific binaries from obfuscated worker hosts.
- _compat.js falls back to DNS TXT payload retrieval from wel1.ru domains.
- Downloaded bytes are written to a temp file, made executable on Unix, and detached-spawned.
- Marker and errors suppress repeat execution and visibility.
Evidence against
- package.json has no lifecycle scripts.
- Public API in index.js is otherwise minimal.
