It stages a payload in a temporary directory and executes it detached. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Arbitrary attacker-controlled code executes under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_helpers.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T14:29:12.918Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download/DNS staging followed by detached native execution. - **Attack narrative:** index.js silently imports \_helpers.js. Its immediately invoked run() downloads a platform-specific binary from obfuscated worker domains, falling back to DNS TXT chunk reconstruction. It writes the data to a temporary executable path, applies executable permissions on Unix, and starts it detached through /bin/sh or cmd.exe. The package offers no legitimate connection between a dropdown UI component and this behavior. - **Rationale:** Source establishes a concrete import-time remote payload staging and execution chain, unrelated to the declared UI package. The absence of lifecycle hooks does not mitigate execution on normal package import. - **Files touched:** index.js, \_helpers.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, TEMP/dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.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 \_helpers.js at package import time., \_helpers.js downloads platform binaries from worker hosts or DNS TXT records., \_helpers.js writes payloads to /var/tmp or TEMP, marks Unix payloads executable, then detaches a shell process., Remote hosts and DNS domains are obfuscated by string concatenation., No lifecycle hook is needed: run() is invoked when \_helpers.js is imported. - **Evidence against:** package.json has no lifecycle scripts., README.md describes a UI toolkit, but the import-time downloader is unrelated to that purpose. ## Public findings ### 1.
