It retrieves a platform-specific executable or DNS-encoded payload, writes it to a temporary directory, and executes it detached. - **Trigger:** Any require/import of devplatform-spa-di - **Impact:** Remote code execution in the importing user's process context. - **Evidence paths:** package.json, index.js, \_polyfill.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T15:27:39.324Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote payload download, staging, and detached execution - **Attack narrative:** On ordinary package import, index.js suppresses errors while loading \_polyfill.js. That module selects an OS payload endpoint, fetches binary data from obfuscated workers.dev hosts or reconstructs it through DNS TXT records, writes it under an innocuous temporary filename, marks it executable on Unix, and starts it detached via /bin/sh or cmd.exe. The code includes a timestamp marker only to limit repeat execution, not to obtain consent. - **Rationale:** This is a concrete, automatically reachable remote binary staging and execution chain concealed behind an unrelated DI package API. The absence of lifecycle scripts does not mitigate import-time execution. - **Files touched:** index.js, \_polyfill.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, TEMP\\analytics\_state, TEMP\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf100-416.workers.dev/pkg/package, 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 imports \_polyfill.js on every package import., \_polyfill.js fetches platform-specific binaries from hidden workers.dev hosts., \_polyfill.js can reconstruct a payload from DNS TXT records under wel1.ru., \_polyfill.js writes the payload to /var/tmp or TEMP, chmods it, then launches it detached through a shell., The download-and-execute path is automatic unless opt-out environment variables are set., lib/telemetry.js contains the same remote native-profiler download, write, and detached-launch mechanism. - **Evidence against:** package.json has no lifecycle scripts., The exported DI API itself is minimal; the malicious behavior is hidden in the import-time sidecar. ## Public findings ### 1.
