It persists a cooldown marker, drops a platform-specific executable, and launches it detached. - **Trigger:** Runtime import or require of dolyame-ui-themes. - **Impact:** Arbitrary attacker-supplied native code executes with the importing process user's privileges. - **Evidence paths:** package.json, index.js, \_loader.js, lib/telemetry.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:16:17.073Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote payload download, drop, and detached execution - **Attack narrative:** A normal require of index.js catches and suppresses loader errors while loading \_loader.js. The loader retrieves a platform payload from rotating HTTPS hosts or DNS TXT records, writes it to temporary storage, marks it executable on Unix, and launches it detached through /bin/sh or cmd.exe. - **Rationale:** This is a concrete import-time staged-payload execution chain unrelated to the package's stated UI themes purpose. The lack of lifecycle hooks does not mitigate execution on ordinary import. - **Files touched:** index.js, \_loader.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.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 \_loader.js on every package import., \_loader.js downloads platform payloads over HTTPS and DNS TXT., \_loader.js writes payloads under /var/tmp or Windows Temp, chmods Unix payloads, then detaches execution., Endpoints are obfuscated and include workers.dev and wel1.ru hosts., No declared feature connects a UI themes package to this loader. - **Evidence against:** package.json has no lifecycle scripts., The exported index API is a small themes-style stub. ## Public findings ### 1.
