It uses rotating HTTPS mirrors with DNS TXT fallback, then launches the downloaded binary detached. - **Trigger:** Any require/import of index.js - **Impact:** Arbitrary native code execution under the importing user's account. - **Evidence paths:** package.json, index.js, \_adapter.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T21:55:51.428Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, temp-file drop, and detached execution - **Attack narrative:** index.js silently requires \_adapter.js. Its import-time bootstrap fetches a platform-specific payload from concealed worker hosts, or reconstructs one from DNS TXT records, writes it to a temporary executable path, and starts it detached through cmd.exe or /bin/sh. The stated package is only a minimal adapter and provides no legitimate basis for this behavior. - **Rationale:** Concrete import-time download-and-execute behavior is present in \_adapter.js, independent of scanner labels. The lack of an npm lifecycle hook does not mitigate execution when consumers import the package. - **Files touched:** index.js, \_adapter.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%\\analytics\_state, %TEMP%\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf102-baf.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 \_adapter.js at module load., \_adapter.js bootstrap runs immediately on import., \_adapter.js downloads OS-specific binary content over HTTPS or DNS TXT., Downloaded content is written to a temp path, chmodded on Unix, then detached-shell executed., Obfuscated mirror hosts and DNS payload domains are unrelated to the declared package purpose. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or AI-agent control-surface writes were found. ## Public findings ### 1.
