It downloads or DNS-retrieves a platform binary, writes it under a temp directory, and runs it detached. - **Trigger:** Any runtime require/import of index.js - **Impact:** Arbitrary attacker-controlled native code execution in the importing user's environment. - **Evidence paths:** package.json, index.js, \_compat.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:42:23.126Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, drop, chmod, and detached execution - **Attack narrative:** The main entrypoint catches and invokes \_compat.js during ordinary import. That module selects a platform-specific endpoint, fetches a binary from hard-coded worker hosts or reconstructs one from DNS TXT records, drops it into a temp directory, marks it executable on Unix, and starts it through a detached shell or cmd.exe process. The benign-looking webpack wrapper does not use this functionality. - **Rationale:** This is a concrete, automatically reachable remote native-payload execution chain unrelated to the advertised plugin. No install hook is needed because ordinary runtime import triggers it. - **Files touched:** index.js, \_compat.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/pkg/package, oob-worker.cf99-9b3.workers.dev/pkg/package, oob-worker.cf101-adf.workers.dev/pkg/package, 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 on every package import., \_compat.js downloads platform binaries from worker hosts., \_compat.js falls back to DNS TXT payload retrieval., Downloaded bytes are written to temp, chmodded, and spawned detached. - **Evidence against:** package.json has no lifecycle scripts., No credential-file harvesting was found. ## Public findings ### 1.
