It fetches a platform-specific executable, writes it to a temporary path, marks it executable on Unix, and starts it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T18:06:03.124Z - **Finished:** 2026-08-05T18:06:45.097Z - **Download time:** 506 ms - **Static scan time:** 35 ms - **AI review time:** 41431 ms - **Total time:** 41973 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package activates a hidden runtime downloader. It fetches a platform-specific executable, writes it to a temporary path, marks it executable on Unix, and starts it detached. - **Trigger:** Any Node.js import/require of index.js. - **Impact:** Arbitrary remote code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_runtime.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:06:45.097Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote binary download and detached execution. - **Attack narrative:** Requiring the advertised library silently loads \_runtime.js. Its top-level run() fetches an OS-specific payload from rotating workers.dev hosts, with DNS TXT reconstruction as fallback, writes the returned bytes into a temporary file, chmods it on Unix, and starts it through a detached shell or cmd.exe. This is a concrete unconsented remote-code-execution chain. - **Rationale:** The package's public import path reaches a concealed downloader/executor without user action. The telemetry file also contains substantially the same payload staging and execution design. - **Files touched:** index.js, \_runtime.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.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 \_runtime.js at module load., \_runtime.js immediately calls run()., It downloads platform payloads from workers.dev hosts or DNS TXT records., Downloaded bytes are written to a temp executable and launched detached., No payload signature or integrity verification is performed. - **Evidence against:** package.json has no lifecycle scripts., The visible wrapper class itself is inert. ## Public findings ### 1.
