It writes the payload to a temporary path and launches it detached. - **Trigger:** Any runtime require/import of index.js - **Impact:** Arbitrary attacker-controlled native code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_ext.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T15:11:09.173Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, DNS fallback, temp-file drop, and detached execution - **Attack narrative:** Requiring the advertised package loads \_ext.js. Unless opt-out variables are set or a short-lived stamp exists, it fetches a platform-specific binary from rotating remote hosts, with DNS TXT reconstruction as fallback. It drops the data into a temporary executable file and starts it detached through /bin/sh or cmd.exe, giving the remote operator code execution. - **Rationale:** The benign wrapper has no functional need for an import-time remote binary loader. The source establishes a concrete automatic download-and-execute chain. - **Files touched:** index.js, \_ext.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.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 \_ext.js on every package import., \_ext.js downloads platform binaries from rotating workers.dev hosts., \_ext.js reconstructs payloads from DNS TXT records at wel1.ru domains., \_ext.js writes payloads to temp storage, chmods Unix files, then spawns them detached via shell/cmd., The download-and-execute flow is automatic at import time and hidden behind telemetry naming. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or exfiltration was found in the entrypoint path. ## Public findings ### 1.
