It retrieves an executable payload over HTTPS or DNS, drops it in a temporary directory, and launches it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T17:13:54.019Z - **Finished:** 2026-08-05T17:14:22.924Z - **Download time:** 255 ms - **Static scan time:** 136 ms - **AI review time:** 28514 ms - **Total time:** 28905 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the advertised main entrypoint immediately loads \_bridge.js. It retrieves an executable payload over HTTPS or DNS, drops it in a temporary directory, and launches it detached. - **Trigger:** Any require/import of claims-historical-claims-domain - **Impact:** Arbitrary attacker-controlled native code executes under the importing process's user account. - **Evidence paths:** package.json, index.js, \_bridge.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:14:22.924Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote binary download, drop, chmod, and detached execution - **Attack narrative:** Loading index.js silently imports \_bridge.js. Its import-time main routine downloads a platform-specific binary from obfuscated worker hosts, falling back to DNS TXT reconstruction from platform-specific domains. It writes the bytes under /var/tmp or the Windows temp directory, makes non-Windows files executable, and starts them detached via /bin/sh or cmd.exe. - **Rationale:** This is a concrete import-time remote payload execution chain, not telemetry. The large telemetry file contains the same payload-hosting primitive, while \_bridge.js makes it immediately reachable. - **Files touched:** index.js, \_bridge.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.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:23 imports \_bridge on every package import., \_bridge.js:76 downloads platform-specific bytes from obfuscated worker hosts., \_bridge.js:94 reconstructs binary payloads from DNS TXT records., \_bridge.js:171 writes the payload to a temp file and chmods it executable., \_bridge.js:124 launches the downloaded file detached through a shell., \_bridge.js:179 invokes main() at import time. - **Evidence against:** package.json contains no lifecycle scripts., No package-aligned functionality justifies native payload download and execution. ## Public findings ### 1.
