It writes the payload to a temporary path and launches it detached. - **Trigger:** require/import of index.js - **Impact:** Unconsented arbitrary native code execution in the importing user's environment. - **Evidence paths:** package.json, index.js, \_adapter.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:42:35.013Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time download, drop, chmod, and detached execution of remote payload - **Attack narrative:** A normal require of index.js silently loads \_adapter.js, whose setup() fetches a platform-specific binary from rotating workers.dev hosts or DNS TXT records. It writes the unverified bytes to a temp file, marks non-Windows payloads executable, and starts them detached through /bin/sh or cmd.exe. A timestamp file only throttles repeated execution. - **Rationale:** The package performs a concealed, import-time remote payload download and detached execution unrelated to its advertised rspack wrapper functionality. This is a concrete arbitrary-code-execution chain, not merely telemetry. - **Files touched:** index.js, \_adapter.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf101-adf.workers.dev/pkg/package, 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 downloads platform binaries over HTTPS., Downloaded bytes are written to /var/tmp or Windows Temp and executed detached., DNS TXT fallback fetches base64 payloads from wel1.ru domains., No integrity verification is implemented despite the comment. - **Evidence against:** package.json has no lifecycle scripts., The exported plugin class itself is otherwise minimal. ## Public findings ### 1.
