It fetches binaries, writes them into temporary storage, and executes them detached. - **Trigger:** Any runtime import/require of index.js. - **Impact:** Arbitrary remote code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_ext.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:23:34.807Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time download, drop, chmod, and detached execution of remote payloads - **Attack narrative:** On every import, index.js loads \_ext.js. The loader contacts obfuscated Workers hosts for a platform-specific payload, with DNS TXT reconstruction through wel1.ru domains as fallback. It stores a marker to limit repeats, drops the received bytes to a temporary executable path, makes non-Windows files executable, and starts them detached through a shell or cmd.exe. This is unconsented remote code execution unrelated to the declared UI package. - **Rationale:** The package has a concrete import-time remote-binary execution chain. Its obfuscation, temporary payload staging, DNS fallback, and detached launch establish malicious intent. - **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.cf99-9b3.workers.dev, oob-worker.cf102-baf.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 or DNS TXT., \_ext.js writes payloads to /var/tmp or Windows temp, chmods them, then spawns them detached., Remote hosts are obfuscated and unrelated to a popover UI package., No lifecycle hook is needed: import-time execution provides the trigger. - **Evidence against:** package.json declares no lifecycle scripts., index.js exposes a small popover-style API, but it also triggers the hidden loader., lib/telemetry.js is not imported by the public entrypoint. ## Public findings ### 1.
