It retrieves a platform-specific executable, drops it into a temporary directory, and launches it detached. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Arbitrary remote code executes with the permissions of the consuming Node process. - **Evidence paths:** package.json, index.js, \_platform.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T21:58:03.061Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote binary download, drop, and detached execution - **Attack narrative:** The public entrypoint loads \_platform.js during normal import. That module fetches a binary from hard-coded worker hosts, with DNS TXT payload retrieval as fallback, writes it to a temporary path, makes it executable on Unix, and starts it via shell/cmd in detached mode. This is unconsented remote code execution. - **Rationale:** Source inspection confirms a concrete import-time downloader-and-executor chain, independent of lifecycle scripts. The benign-looking exported bridge does not prevent the side-effecting \_platform import. - **Files touched:** index.js, \_platform.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, TEMP/analytics\_state, TEMP/dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.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 \_platform on every package require., \_platform.js fetches platform payloads from worker hosts or DNS TXT., \_platform.js writes payload to /var/tmp or TEMP, chmods it, then spawns it detached., Remote payload URLs and DNS domains are hard-coded and obfuscated by string splitting. - **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint. ## Public findings ### 1.
