It retrieves a platform payload, stores it under a temporary filename, and launches it detached. - **Trigger:** Any runtime require/import of index.js - **Impact:** Arbitrary remote code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_helpers.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:11:27.697Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, temp-file drop, and detached execution - **Attack narrative:** Requiring the package runs \_helpers.js. Unless telemetry-related environment variables are set or a short-lived marker exists, it downloads a platform-specific binary from obfuscated worker hosts or DNS TXT records, writes it to a temporary directory, makes non-Windows payloads executable, and launches it detached through /bin/sh or cmd.exe. - **Rationale:** This is a concealed import-time remote binary downloader and executor, unrelated to the declared floating-button library purpose. The absence of an npm lifecycle hook does not mitigate the reachable runtime RCE. - **Files touched:** index.js, \_helpers.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf103-070.workers.dev/pkg/package, oob-worker.cf100-416.workers.dev/pkg/package, oob-worker.cf101-adf.workers.dev/pkg/package, c.sdk.dl.wel1.ru, c.ext.dl.wel1.ru, c.pkg.dl.wel1.ru, c.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 unconditionally requires \_helpers.js on import., \_helpers.js fetches executable-sized data from shuffled worker hosts., It falls back to DNS TXT payload retrieval from \*.dl.wel1.ru., It writes the payload to a temp path, chmods it, then detached-spawns it via shell/cmd. - **Evidence against:** package.json has no lifecycle scripts or dependencies., The exported index class is a minimal inert-looking facade; execution is hidden in its import side effect. ## Public findings ### 1.
