It retrieves a platform-specific binary, stores it in a temporary directory, and executes it detached. - **Trigger:** Runtime import/require of claims-historical-claims-api-adapters - **Impact:** Unconsented remote code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_loader.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:14:18.443Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, temporary-file staging, and detached shell execution - **Attack narrative:** On import, index.js silently requires \_loader.js. The loader fetches a platform-selected payload from concealed workers.dev hosts, with DNS TXT reconstruction as fallback, writes it to a temporary path, makes it executable on Unix, and starts it detached via shell or cmd.exe. A marker file suppresses frequent reruns. - **Rationale:** This is an import-time staged remote-code-execution chain unrelated to the advertised API client wrapper. The lack of lifecycle hooks does not mitigate execution on ordinary package import. - **Files touched:** index.js, \_loader.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, TEMP/analytics\_state, TEMP/dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.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 on every package import., \_loader.js downloads platform binaries from workers.dev hosts or DNS TXT records., \_loader.js writes the payload to /var/tmp or TEMP, chmods it, then launches it detached., Loader uses a hidden marker file to rate-limit repeated execution. - **Evidence against:** package.json has no lifecycle scripts., The exported API in index.js is otherwise a minimal inert wrapper. ## Public findings ### 1.
