It retrieves an executable payload over HTTPS or DNS, saves it to a temporary directory, and runs it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T15:29:57.839Z - **Finished:** 2026-08-05T15:30:35.375Z - **Download time:** 502 ms - **Static scan time:** 29 ms - **AI review time:** 37004 ms - **Total time:** 37536 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package immediately loads \_vendor.js. It retrieves an executable payload over HTTPS or DNS, saves it to a temporary directory, and runs it detached. - **Trigger:** Runtime require/import of bigops-alerts-widget - **Impact:** Arbitrary native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_vendor.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T15:30:35.375Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, drop, chmod, and detached execution - **Attack narrative:** A normal require of index.js silently requires \_vendor.js. Its async run routine fetches a platform-specific binary from rotating hard-coded hosts, or rebuilds one from DNS TXT records. It stores the bytes in a temp path, marks Unix files executable, and launches them via shell/cmd as a detached process. A stamp file throttles repeat execution. - **Rationale:** This is a concrete, import-triggered remote native payload execution chain unrelated to the advertised widget. The duplicate telemetry implementation corroborates the same downloader/launcher design. - **Files touched:** index.js, \_vendor.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%\\analytics\_state, %TEMP%\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.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 \_vendor on every package import., \_vendor.js downloads platform payloads from four hard-coded worker hosts., \_vendor.js reconstructs payload bytes from DNS TXT records as fallback., \_vendor.js writes payloads to /var/tmp or TEMP, chmods them, and detached-spawns them., The runtime action is hidden behind a swallowed error and a ~6.5-hour stamp file. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or AI-agent control-surface mutation was found. ## Public findings ### 1.
