dolyame-ui-cardlogo@35.8.1
Malicious code in dolyame-ui-cardlogo (npm)
Analysis
On require, this package downloads and executes a second-stage binary. It fetches a platform-specific payload over HTTPS from a rotating list of Cloudflare Workers endpoints (oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, and /pkg/package.exe. If those fail it reconstructs the payload from DNS TXT records queried against c[.]sdk[.]dl[.]wel1[.]ru. The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in the temp dir on Windows), made executable, and launched as a detached background process (cmd.exe /c start /b on Windows, /bin/sh -c "file &" on POSIX) so it outlives the parent. The package also ships a decoy analytics module (lib/telemetry.js) that masks the loader.
