It retrieves a platform-specific binary, drops it into a temporary directory, and launches it detached. - **Trigger:** Any runtime require/import of index.js - **Impact:** Arbitrary remote code executes with the privileges of the importing Node.js process. - **Evidence paths:** package.json, index.js, \_support.js, README.md, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:00:40.278Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, drop, chmod, and detached execution - **Attack narrative:** A normal import reaches \_support.js via a swallowed require. That module contacts obfuscated worker hosts for a platform-specific payload, then falls back to DNS TXT records, writes the received bytes to a temp path, makes Unix payloads executable, and launches them through a detached shell or cmd.exe process. This is a concrete remote-code-execution loader unrelated to the package's stated interface. - **Rationale:** The entrypoint makes remote payload execution import-time behavior, not an inert or user-invoked utility. Lack of lifecycle hooks does not mitigate arbitrary execution when an application imports the package. - **Files touched:** index.js, \_support.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%/analytics\_state, %TEMP%/dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.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 \_support.js on every package require, \_support.js downloads platform-specific binary payloads over HTTPS, \_support.js falls back to DNS TXT payload retrieval, Downloaded bytes are written to /var/tmp or Windows temp, chmodded, and spawned detached, Remote hosts and DNS domains are obfuscated by string joining - **Evidence against:** package.json has no lifecycle scripts, No AI-agent control-surface modification found ## Public findings ### 1.
