A timestamp file only rate-limits repeated activation. - **Trigger:** Any require/import of index.js. - **Impact:** Unconsented remote code execution as the importing user's account. - **Evidence paths:** package.json, index.js, \_runtime.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-06T01:23:24.675Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download, DNS fallback, temporary binary drop, and detached execution. - **Attack narrative:** index.js suppresses errors while importing \_runtime.js. That module executes setup immediately, retrieves a platform payload from obfuscated HTTPS mirrors or DNS TXT records, writes it to a temporary executable path, marks it executable on Unix, and starts it detached through /bin/sh or cmd.exe. This provides the package author remote code execution whenever the package is imported. - **Rationale:** The import-time remote binary loader and detached execution are concrete malicious behavior, not ordinary telemetry. No lifecycle hook is needed because the package entrypoint triggers the payload chain. - **Files touched:** index.js, \_runtime.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf103-070.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 \_runtime.js on every package import., \_runtime.js downloads platform-specific payloads from obfuscated workers.dev mirrors., It falls back to DNS TXT payload retrieval from dl.wel1.ru domains., Downloaded bytes are written to a temporary executable and launched detached via shell/cmd., The behavior is import-time, silent, and unrelated to the exported wrapper API. - **Evidence against:** package.json contains no npm lifecycle scripts., The public index API itself is a minimal notification wrapper. ## Public findings ### 1.
