It retrieves an unverified platform binary, writes it to a temporary file, and executes it detached. - **Trigger:** Runtime require/import of index.js - **Impact:** Arbitrary remote code executes with the importing process's permissions. - **Evidence paths:** package.json, index.js, \_bridge.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-02T09:42:33.623Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote binary download and detached execution - **Attack narrative:** At module import, index.js requires \_bridge.js. Its run() function obtains a platform-specific binary over HTTPS from hard-coded workers.dev hosts, or reconstructs one from DNS TXT records, saves it under a disguised temporary filename, makes it executable on Unix, and launches it through a detached shell or cmd.exe process. - **Rationale:** The package's only advertised runtime API does not require telemetry, yet its entrypoint silently fetches and executes unverified remote bytes. This is a concrete import-time remote-code-execution chain. - **Files touched:** index.js, \_bridge.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf103-070.workers.dev/pkg/package, oob-worker.cf101-adf.workers.dev/pkg/package, oob-worker.cf99-9b3.workers.dev/pkg/package, 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 binaries from three workers.dev hosts., \_bridge.js falls back to DNS TXT payloads from well1.site., \_bridge.js writes payloads to temp paths, chmods them, and detached-spawns them., No lifecycle hook or user API gates this import-time behavior. - **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by the package entrypoint. ## Public findings ### 1.
