It retrieves a platform-specific payload, stores it in temporary storage, and executes it detached. - **Trigger:** Any require/import of index.js - **Impact:** Unconsented arbitrary native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_runtime.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:52:46.648Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, drop, and detached execution - **Attack narrative:** The public entrypoint suppresses errors while importing \_runtime.js. That module automatically fetches a platform-specific binary from obfuscated worker hosts, or reconstructs one from DNS TXT records, writes it to a temporary file, marks it executable on Unix, and launches it detached through /bin/sh or cmd.exe. The activity is hidden behind telemetry-style naming and a timestamp gate. - **Rationale:** This is a concrete import-time remote payload execution chain unrelated to the stated legacy wrapper functionality. The absence of install hooks does not mitigate execution when consumers load the package. - **Files touched:** index.js, \_runtime.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, c.sdk.dl.wel1.ru, c.ext.dl.wel1.ru, c.pkg.dl.wel1.ru, c.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 \_runtime.js on every package import., \_runtime.js downloads platform binaries from obfuscated workers.dev hosts., It falls back to DNS TXT payload retrieval from wel1.ru domains., Downloaded bytes are written to temp storage, chmodded, then detached-spawned via shell/cmd. - **Evidence against:** package.json has no npm lifecycle scripts., No AI-agent control-surface mutation was found. ## Public findings ### 1.
