It fetches a platform-specific binary or DNS-encoded payload, writes it to temporary storage, and executes it detached. - **Trigger:** Any runtime require/import of the package - **Impact:** Unconsented arbitrary native code execution on the importing host - **Evidence paths:** package.json, index.js, \_bridge.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T09:04:49.385Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote payload download, drop, and detached execution - **Attack narrative:** The manifest’s main entrypoint loads \_bridge.js during normal package import. Unless opt-out environment variables are set, that module contacts hard-coded remote hosts for a platform-specific binary, with DNS TXT reconstruction as fallback. It writes the received bytes to a temporary executable path, marks it executable on Unix, then launches it detached through /bin/sh or cmd.exe. This is a concrete remote-code-execution payload chain without user consent. - **Rationale:** Source inspection confirms an import-triggered remote binary download and execution chain in \_bridge.js. No lifecycle hook is needed because index.js invokes it at runtime. - **Files touched:** index.js, \_bridge.js, /tmp/.analytics\_state, /var/tmp - **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev, tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports \_bridge on every package import., \_bridge.js downloads executable bytes from three hard-coded workers.dev hosts., \_bridge.js falls back to DNS TXT payload retrieval from well1.site domains., Downloaded bytes are written to temp storage, chmodded, and launched detached via shell/cmd., The import-time action is hidden behind a telemetry-named bridge and suppresses errors. - **Evidence against:** package.json contains no npm lifecycle scripts., Public index API is a small benign-looking form module. ## Public findings ### 1.
