bigops-frontend-bigops-frontend-core@35.1.5

Analysis

On require(), the package executes _vendor.js which downloads a native binary from Cloudflare Workers C2 infrastructure (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev) via HTTPS, with DNS TXT-record fallback through sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, and net[.]dl[.]wel1[.]ru. The downloaded binary is written to /var/tmp/.cache_<random> (Linux) or %TEMP%\dotnet_diag_<random>.exe (Windows) and spawned as a detached process. A cache file at /tmp/.analytics_state (or %TEMP%\analytics_state) prevents re-download within ~6.35 hours. The package has no repository and no README.
