dolyame-ui-skeleton@35.2.5
Malicious code in dolyame-ui-skeleton (npm)
Analysis
dolyame-ui-skeleton@35.2.5 is a remote-code-execution dropper. Loading the package (index.js requires _vendor.js) triggers a downloader that fetches a binary payload over HTTPS from Cloudflare Workers endpoints oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, and oob-worker[.]cf99-9b3[.]workers[.]dev at platform-selected paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe. If HTTPS fails it falls back to DNS TXT chunked base64 retrieval from c[.]sdk[.]dl[.]wel1[.]ru. The downloaded payload is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in %TEMP% on Windows), made executable, and launched detached via /bin/sh -c "<path> &" or cmd.exe /c start /b. The package ships no actual UI component code; its sole purpose is to download and execute a remote binary.
