AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time staged payload chain with remote code execution, not ordinary telemetry. The unused telemetry file also contains materially similar downloader/launcher primitives, reinforcing intentional concealment.
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
Unconsented remote code execution under the importing process's user privileges.
Mechanism
Import-time remote binary download, drop, chmod, and detached execution.
Attack narrative
Requiring index.js silently requires _shim.js, whose top-level run() function creates a temporary stamp, retrieves a platform-specific opaque payload from rotating HTTPS hosts or DNS TXT records, writes it to a temporary file, makes it executable on Unix, and launches it detached via shell or cmd.exe. The package provides no legitimate reason for this import-time downloader/executor.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _shim.js on every package import.
- _shim.js runs immediately and fetches platform payloads over HTTPS or DNS TXT.
- Downloaded bytes are written to a temp executable path, chmodded on Unix, and spawned detached.
- Remote hosts are obfuscated by string concatenation and include workers.dev and wel1.ru domains.
- Payload execution is silent; errors are swallowed and a temp stamp suppresses repeats.
Evidence against
- package.json contains no lifecycle scripts.
- The exported button-set class itself is minimal; the malicious behavior is the hidden import-time shim.
