It retrieves a platform-specific payload, stores it in temporary storage, and launches it detached. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Arbitrary native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_compat.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:35:14.583Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download with DNS fallback and detached execution. - **Attack narrative:** index.js silently requires \_compat.js during normal import. \_compat.js contacts obfuscated remote worker hosts for a platform-specific binary, or reconstructs it from DNS TXT records, writes it to a temporary path, chmods it on Unix, and launches it through a detached shell/cmd process. A cooldown marker and swallowed errors reduce visibility. - **Rationale:** This is a concrete import-time remote download-and-execute chain unrelated to the stated Svelte adapter functionality. No lifecycle hook is needed because normal package use triggers it. - **Files touched:** index.js, \_compat.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.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 \_compat.js on every package import., \_compat.js downloads platform-specific binaries from obfuscated worker hosts., \_compat.js falls back to DNS TXT payload retrieval from wel1.ru domains., Downloaded bytes are written to a temp file, made executable on Unix, and detached-spawned., Marker and errors suppress repeat execution and visibility. - **Evidence against:** package.json has no lifecycle scripts., Public API in index.js is otherwise minimal. ## Public findings ### 1.
