It retrieves a platform-specific payload over HTTPS or DNS TXT, writes it to temporary storage, and launches it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T15:27:01.574Z - **Finished:** 2026-08-05T15:27:39.613Z - **Download time:** 501 ms - **Static scan time:** 129 ms - **AI review time:** 37408 ms - **Total time:** 38039 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package silently runs a remote binary downloader. It retrieves a platform-specific payload over HTTPS or DNS TXT, writes it to temporary storage, and launches it detached. - **Trigger:** Runtime import/require of devplatform-spa-feature-toggle - **Impact:** Arbitrary code execution as the importing process user. - **Evidence paths:** index.js, \_bridge.js, package.json, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T15:27:39.613Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote payload download and execution - **Attack narrative:** index.js imports \_bridge.js during ordinary package loading. \_bridge.js fetches a platform-specific binary from hard-coded worker domains, or reconstructs one from DNS TXT records, writes it under a temporary directory, makes it executable on Unix, and starts it detached via shell or cmd.exe. - **Rationale:** The advertised feature-toggle entrypoint has no need for an import-time remote binary bootstrap. The concrete downloader-to-temp-file-to-detached-execution chain is malicious. - **Files touched:** index.js, \_bridge.js, /tmp/.analytics\_state - **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.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 \_bridge.js at module load., \_bridge.js downloads platform payloads from worker hosts., It falls back to DNS TXT payload retrieval., Downloaded bytes are written, chmodded, and spawned detached. - **Evidence against:** package.json has no lifecycle hooks., No credential harvesting was found in the inspected entry path. ## Public findings ### 1.
