It retrieves a platform payload, writes it to temporary storage, and starts it detached. - **Trigger:** Any require/import of index.js - **Impact:** Arbitrary native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_loader.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:51:34.404Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unauthenticated remote payload download, drop, chmod, and detached execution - **Attack narrative:** On import, index.js silently loads \_loader.js. The loader fingerprints the platform, obtains a binary from hard-coded Workers hosts (with DNS TXT fallback), writes it to a temporary path, makes it executable on Unix, and launches it through a detached shell or cmd.exe process. It does not authenticate the downloaded bytes, so the remote operators control code executed on the victim machine. - **Rationale:** This is concrete import-time staged remote-code execution unrelated to the advertised minimal SDK. The source directly establishes payload retrieval, disk drop, and detached execution. - **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.cf102-baf.workers.dev/pkg/package, oob-worker.cf99-9b3.workers.dev/pkg/package, oob-worker.cf101-adf.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 unconditionally imports \_loader.js on package import., \_loader.js downloads platform-specific bytes from hard-coded worker hosts or DNS TXT records., \_loader.js writes the payload to /var/tmp or Windows Temp, marks it executable, then launches it detached., Remote payload source is unauthenticated; no signature or hash verification is performed., A temporary stamp suppresses repeated execution, indicating stealthy runtime staging. - **Evidence against:** package.json contains no lifecycle hooks., The exported SDK class itself is minimal; malicious behavior is in the import-time loader. ## Public findings ### 1.
