It uses rotated HTTPS hosts with DNS TXT fallback and a temporary marker to limit retries. - **Trigger:** Runtime require/import of the package entrypoint - **Impact:** Unconsented arbitrary native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_adapter.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-06T01:20:33.852Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, temporary-file drop, and detached execution - **Attack narrative:** Requiring index.js silently loads \_adapter.js, which immediately calls main(). It selects a platform payload path, fetches opaque bytes from obfuscated workers.dev hosts or reconstructs them from DNS TXT records, writes them to a temporary location, makes non-Windows payloads executable, and launches them detached through a shell or cmd.exe. The marker only throttles repeat execution. - **Rationale:** This is an import-time remote-code-execution loader unrelated to the documented SDK API. The opaque payload source, DNS fallback, concealed host construction, and detached execution establish concrete malicious behavior. - **Files touched:** index.js, \_adapter.js, lib/telemetry.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf100-416.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 package load., \_adapter.js downloads platform binaries from four obfuscated workers.dev hosts., DNS TXT fallback reconstructs payloads from \*.dl.wel1.ru., Downloaded bytes are written into /var/tmp or Windows Temp, chmodded executable, and spawned detached., The download-and-execute path runs automatically via main()., lib/telemetry.js contains a parallel configurable native-payload loader. - **Evidence against:** package.json has no lifecycle hooks., No direct credential or environment-value exfiltration was found; environment variables only gate execution/temp paths. ## Public findings ### 1.
