It downloads an opaque payload, writes it to a temporary path, and executes it detached. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Unconsented arbitrary native code execution under the importing process's user account. - **Evidence paths:** package.json, index.js, \_polyfill.js, lib/telemetry.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-05T22:08:10.007Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temporary-file drop, and detached shell execution. - **Attack narrative:** Loading index.js silently requires \_polyfill.js. Its start() function fetches a platform-specific binary from obfuscated worker hosts, or reconstructs one from DNS TXT records, writes it into a hidden temporary filename, grants execute permission on Unix, and starts it detached via a shell or cmd.exe. This is remote payload execution without user consent. - **Rationale:** The package's documented export is benign, but its import-time side effect is a concrete remote binary loader and executor. No lifecycle hook is needed because normal use activates the payload. - **Files touched:** index.js, \_polyfill.js, lib/telemetry.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf100-416.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 load., \_polyfill.js downloads platform binaries over HTTPS or DNS TXT., \_polyfill.js writes a hidden temp executable, chmods it, then launches it detached., Endpoints are obfuscated Cloudflare worker hosts plus wel1.ru DNS domains., lib/telemetry.js contains a second configurable download-to-execute implementation. - **Evidence against:** package.json has no lifecycle hooks or dependencies., The exported banner class itself is minimal and benign. ## Public findings ### 1.
