It downloads a platform-specific payload, writes it to temporary storage, and executes it detached. - **Trigger:** Any require/import of the package main entrypoint. - **Impact:** Arbitrary remote code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_support.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:56:17.368Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, drop, chmod, and detached execution - **Attack narrative:** The public entrypoint silently requires \_support.js. On import, it selects a platform payload URL, retrieves a binary from rotating external hosts or reconstructs one through DNS TXT records, stores it in a temporary directory, marks it executable on Unix, and starts it detached. The temporary state file merely limits repeated execution. - **Rationale:** This is concrete import-time remote payload execution unrelated to the advertised UI toolkit. No lifecycle hook is needed because the package main entrypoint reaches the bootstrapper. - **Files touched:** index.js, \_support.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.cf100-416.workers.dev, oob-worker.cf103-070.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 imports \_support.js on every package import., \_support.js downloads platform binaries from worker hosts., Downloaded bytes are written to /var/tmp or Windows Temp and made executable., \_support.js launches the downloaded file detached via shell/cmd., DNS TXT fallback reconstructs a binary payload from dl.wel1.ru domains., The behavior is silent and only throttled by a temporary state file. - **Evidence against:** package.json contains no lifecycle scripts., The exported UI class in index.js is otherwise minimal. ## Public findings ### 1.
