Importing the package silently starts a bootstrapper that retrieves an opaque platform payload and executes it detached. It persists a short cooldown marker to suppress repeated activation.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

Any runtime import/require of the package entrypoint.

Impact

Unconsented remote code execution in the importing process's user context.

Mechanism

Remote binary download (HTTPS or DNS TXT), temp-file drop, chmod, and detached shell execution.

Attack narrative

Requiring index.js loads _shim.js. Its bootstrap function contacts rotating workers.dev hosts for a platform-specific executable, or reconstructs one through DNS TXT records under dl.wel1.ru. It saves the opaque bytes in a temporary directory, makes non-Windows payloads executable, and launches them detached through /bin/sh or cmd.exe. The same package also contains a configurable duplicate loader in lib/telemetry.js.

Rationale

This is a concrete import-time staged payload delivery and execution chain, unrelated to the declared infrastructure-utilities package purpose. Absence of an install hook does not mitigate runtime remote code execution on import.

Evidence

Network endpoints8

On require() of the package, _shim.js executes a bootstrap() at module top level that fetches a platform-specific native binary from string-concatenation-obfuscated hosts under oob-worker.cf10{0,1,2}-*.workers.dev, with a base64 DNS-TXT fallback under *.dl.wel1.ru. The fetched bytes are written to /var/tmp/.cache_<rand> (POSIX) or %TEMP%\dotnet_diag_<rand>.exe (Windows), chmod'd 0755, and detached-spawned via /bin/sh -c or cmd /c start /b. The exported main lib/telemetry.js contains a duplicate download-decode-chmod-exec chain (Buffer.from(chunks,'base64'), fs['chmod'+'Sync'](...,0o755), cp.spawn('/bin/sh',['-c', filePath + ' &'],{detached:true})) presented under an SDK/telemetry cover story. Destination hostnames and dangerous identifiers (require('child_'+'process'), fs['chmod'+'Sync']) are constructed via array-join and string concatenation to defeat static analysis. Endpoint shuffling, cache/cooldown files, and opt-out env checks are consistent with anti-analysis rather than legitimate telemetry.
