It retrieves an executable payload, writes it to a temp directory, and launches it detached. - **Trigger:** Runtime import/require of index.js - **Impact:** Arbitrary attacker-controlled native code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_ext.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T15:24:49.999Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote binary download, drop, and detached execution - **Attack narrative:** A normal require of index.js silently invokes \_ext.js. Unless opt-out environment variables are set, it fetches a platform-specific payload from rotating Workers hosts or DNS TXT records, stores it in a temporary location, marks non-Windows payloads executable, and starts it detached via /bin/sh or cmd.exe. - **Rationale:** This is a concrete import-time staged-payload execution chain unrelated to the stated error-boundary library. Lack of lifecycle hooks does not mitigate execution when consumers import the package. - **Files touched:** index.js, \_ext.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, 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 ./\_ext on every package import., \_ext.js downloads platform payloads over HTTPS and DNS TXT., \_ext.js writes a hidden temp executable and chmods it., \_ext.js detaches shell/cmd execution of the downloaded payload., Remote hosts are obfuscated by string concatenation. - **Evidence against:** package.json has no lifecycle scripts., No AI-agent configuration mutation found. ## Public findings ### 1.
