It saves a platform-specific payload in a temporary directory and executes it detached. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Arbitrary attacker-controlled native code executes as the importing user. - **Evidence paths:** index.js, \_shim.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-05T13:20:15.758Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download, temporary-file drop, and detached execution. - **Attack narrative:** The package’s ordinary import path loads \_shim.js, whose top-level call starts an asynchronous downloader. It tries obfuscated workers.dev endpoints and then DNS TXT records for platform-specific payload bytes, stores a sufficiently large result under /var/tmp or the Windows temp directory, marks Unix payloads executable, and starts them detached through /bin/sh or cmd.exe. - **Rationale:** This is concrete import-time remote code execution concealed behind an unrelated wrapper API. The absence of lifecycle scripts does not mitigate execution when consumers import the package. - **Files touched:** index.js, \_shim.js - **Network endpoints:** oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports \_shim.js on every package import., \_shim.js immediately invokes run() at module load., \_shim.js downloads platform binaries from three workers.dev hosts or DNS TXT fallbacks., \_shim.js writes the downloaded payload to a temp path, chmods it on Unix, then launches it detached via shell/cmd., The public API is a minimal inert wrapper unrelated to this downloader. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or AI-agent configuration mutation was found. ## Public findings ### 1.
