AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time remote payload execution chain unrelated to the package’s advertised abstraction API. The absence of lifecycle hooks does not mitigate runtime RCE on ordinary use.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Any require/import of index.js at application runtime.
Impact
Arbitrary attacker-controlled native code execution as the importing process user.
Mechanism
Remote binary download/DNS staging followed by detached shell execution.
Attack narrative
Importing index.js requires _support.js. Its start routine fetches a platform-specific binary from hard-coded workers.dev hosts, or assembles one from DNS TXT records, writes it to a temp directory, sets executable permissions on Unix, and starts it detached via /bin/sh or cmd.exe. The payload is unauthenticated and its execution is hidden by swallowed errors and ignored stdio.
AI rationale
This is a concrete import-time remote payload execution chain unrelated to the package’s advertised abstraction API. The absence of lifecycle hooks does not mitigate runtime RCE on ordinary use.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _support.js on every package import.
- _support.js downloads platform binaries from three workers.dev hosts.
- _support.js can reconstruct payloads through DNS TXT records under dl.wel1.ru.
- Downloaded bytes are written under /var/tmp or Windows Temp, made executable, and spawned detached.
- No checksum/signature validation occurs before execution.
Evidence against
- package.json has no lifecycle scripts; execution is triggered by runtime import.
