The payload is fetched by HTTPS or DNS TXT fallback, stored in a temporary directory, then launched. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Arbitrary code execution as the importing user's account. - **Evidence paths:** package.json, index.js, \_ext.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T14:24:22.441Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temporary-file drop, chmod, and detached shell execution. - **Attack narrative:** The main entrypoint suppresses errors while requiring \_ext.js. On import, \_ext.js fetches a platform-specific binary from hard-coded obfuscated hosts, falling back to DNS TXT payload reconstruction. It writes the payload to a temporary path, makes it executable on Unix, and launches it detached through /bin/sh or cmd.exe without validating its origin or contents. - **Rationale:** This is concrete import-time remote payload execution unrelated to the advertised UI mixins package. The dormant telemetry module repeats the same downloader/launcher pattern, reinforcing intentional staging behavior. - **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.cf103-070.workers.dev, oob-worker.cf100-416.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 \_ext.js on every package import., \_ext.js downloads platform binaries from three obfuscated worker hosts., \_ext.js can retrieve a payload via DNS TXT records from dl.wel1.ru domains., \_ext.js writes the downloaded payload to /var/tmp or Windows Temp, chmods it, and starts it detached., No integrity/signature validation is performed before execution. - **Evidence against:** package.json contains no npm lifecycle script., The exported mixin class itself is minimal, but its import triggers \_ext.js. ## Public findings ### 1.
