It retrieves a platform-specific binary, writes it to a temporary directory, and executes it detached. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Arbitrary attacker-controlled code execution under the consuming application's user account. - **Evidence paths:** package.json, index.js, \_ext.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:58:29.536Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download/DNS staging followed by detached execution. - **Attack narrative:** A normal application import reaches index.js, which suppresses errors while loading \_ext.js. That module fetches a platform-specific payload from rotating external hosts, or reconstructs one from DNS TXT records, stores it in a temp directory, marks it executable on Unix, and starts it detached. The payload is neither bundled nor verified, allowing remote control of executed code. - **Rationale:** This is concrete, silent import-time remote payload staging and execution, not ordinary telemetry. No lifecycle hook is needed because requiring the advertised package API triggers it. - **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:** https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, c.sdk.dl.wel1.ru, c.ext.dl.wel1.ru, c.pkg.dl.wel1.ru, c.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.js on every package import., \_ext.js downloads platform-specific binaries from rotating workers.dev hosts., \_ext.js reconstructs payloads from DNS TXT records as an HTTPS fallback., \_ext.js writes the payload to /var/tmp or Windows temp, chmods it, then launches it detached via shell/cmd. - **Evidence against:** package.json has no lifecycle scripts., The documented API in index.js is minimal, but it silently triggers the payload loader. ## Public findings ### 1.
