It downloads an opaque executable, writes it to temporary storage, and runs it detached. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Arbitrary code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_loader.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T14:51:19.070Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, DNS fallback, temporary-file staging, and detached execution. - **Attack narrative:** The public entrypoint silently requires \_loader.js. On import, it retrieves an opaque platform payload from rotating HTTPS hosts or DNS TXT records, writes it under a random temporary filename, marks it executable on Unix, and starts it detached through a shell or cmd.exe. The similarly capable telemetry module is not exported by the public entrypoint, but the active loader independently establishes the execution chain. - **Rationale:** This is a concrete import-time staged-payload execution chain unrelated to the declared fonts functionality. Absence of lifecycle hooks does not mitigate the automatic runtime trigger. - **Files touched:** index.js, \_loader.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.cf103-070.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:23 imports \_loader.js on every package import., \_loader.js:72 downloads platform-specific payloads from obfuscated worker hosts., \_loader.js:154 fetches base64 payloads through DNS TXT fallback., \_loader.js:166 writes payload to a temp path, chmods it, then spawns it detached., \_loader.js:138 creates a temporary marker to throttle execution. - **Evidence against:** package.json has no lifecycle scripts., Public font API in index.js is otherwise minimal., No credential harvesting or AI-agent configuration writes were found. ## Public findings ### 1.
