It downloads bytes from hard-coded remote infrastructure or DNS TXT records, writes an executable temporary file, and launches it detached. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Unconsented remote code execution with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_vendor.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:37:31.625Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic remote binary download, drop, chmod, and detached execution - **Attack narrative:** Requiring index.js silently requires \_vendor.js. Its import-time init selects an OS-specific URL, fetches a payload from hard-coded worker hosts or reconstructs it from DNS TXT records, writes it to a temporary executable path, grants execute permission on Unix, and starts it detached through a shell or cmd.exe. Failures are suppressed and a temporary timestamp suppresses repeated attempts. - **Rationale:** The package's advertised HTTP wrapper has an import-time, concealed remote binary execution chain unrelated to its stated function. This is concrete malware behavior, not merely telemetry. - **Files touched:** /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%/analytics\_state, %TEMP%/dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf102-baf.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 \_vendor.js on every package import., \_vendor.js fetches executable-sized bytes from rotating remote hosts or DNS TXT., \_vendor.js writes the payload under /var/tmp or Windows Temp, chmods it, and detached-spawns it., The loader is silent, runs automatically, and uses a timestamp file to limit retries. - **Evidence against:** package.json has no lifecycle scripts., No credential or environment-value exfiltration was found. ## Public findings ### 1.
