It persists a temporary binary and executes it detached. - **Trigger:** Runtime require/import of dolyame-ui-utils - **Impact:** Remote code execution with the importing process user's privileges. - **Evidence paths:** package.json, index.js, \_polyfill.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:13:54.179Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, temporary-file write, chmod, and detached shell execution - **Attack narrative:** index.js suppresses errors while requiring \_polyfill.js. That module runs setup at import time, retrieves a platform-specific payload over HTTPS or reconstructed DNS TXT records, stores it in /var/tmp or Windows Temp, makes it executable on Unix, and starts it detached through a shell or cmd.exe. - **Rationale:** This is concrete import-time remote payload execution, not legitimate utility behavior. The lack of an npm lifecycle hook does not mitigate runtime execution on require. - **Files touched:** index.js, \_polyfill.js - **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf101-adf.workers.dev, 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 \_polyfill on every package require., \_polyfill.js immediately invokes setup()., \_polyfill.js downloads platform binaries then writes and executes them., DNS TXT fallback reconstructs executable bytes from untrusted remote DNS data., Payload hosts are obfuscated and include workers.dev and wel1.ru domains. - **Evidence against:** package.json has no lifecycle scripts., Public utility exports are otherwise simple helpers. ## Public findings ### 1.
