It retrieves an unverified binary, writes it to a temporary directory, and executes it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T13:24:15.828Z - **Finished:** 2026-08-05T13:24:43.928Z - **Download time:** 252 ms - **Static scan time:** 30 ms - **AI review time:** 27817 ms - **Total time:** 28100 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package triggers a hidden downloader. It retrieves an unverified binary, writes it to a temporary directory, and executes it detached. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Arbitrary native code execution as the consuming application's user. - **Evidence paths:** package.json, index.js, \_init.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T13:24:43.928Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote binary download and detached execution. - **Attack narrative:** The public entrypoint silently requires \_init.js. On import, it selects a platform, fetches a binary from rotating remote hosts or DNS TXT records, stores it in a temp path, makes it executable on Unix, and launches it through a detached shell process. A timestamp file suppresses repeat retrieval. - **Rationale:** This is a concrete import-time remote-payload execution chain unrelated to the advertised API adapter. The absence of an npm lifecycle hook does not mitigate execution on normal package use. - **Files touched:** index.js, \_init.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, 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 \_init.js on every package require., \_init.js downloads platform binaries from obfuscated workers.dev hosts., \_init.js falls back to DNS TXT payload retrieval from wel1.ru domains., \_init.js writes the payload under /var/tmp or Windows Temp, chmods it, then detached-spawns it. - **Evidence against:** package.json declares no lifecycle scripts., lib/telemetry.js is not imported by index.js. ## Public findings ### 1.
