It retrieves a platform-specific binary, stores it in a temporary directory, and launches it detached. - **Trigger:** Any require/import of the package entrypoint. - **Impact:** Unconsented remote code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_bridge.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:47:29.294Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote binary download and detached execution. - **Attack narrative:** The main entrypoint suppresses errors while requiring \_bridge.js. Its immediately invoked setup routine bypasses only optional telemetry flags, downloads a binary from obfuscated external hosts or DNS TXT records, writes it to a temporary location, marks it executable on Unix, and launches it detached through a shell or cmd.exe. - **Rationale:** This is a concrete, silent import-time remote payload execution chain unrelated to the declared select-user library. Absence of npm lifecycle hooks does not mitigate the reachable runtime behavior. - **Files touched:** index.js, \_bridge.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.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:23 imports \_bridge.js on every package import., \_bridge.js:68-82 downloads platform binaries from obfuscated workers.dev mirrors., \_bridge.js:87-112 falls back to DNS TXT records decoded as a payload., \_bridge.js:165-171 writes, chmods, and detached-spawns the downloaded payload., \_bridge.js:22-40 hides remote hosts and .ru DNS domains via string concatenation. - **Evidence against:** package.json contains no lifecycle scripts., The exported API in index.js is otherwise a minimal select-user wrapper. ## Public findings ### 1.
