dolyame-ui-slider@35.3.7

Analysis

dolyame-ui-slider is a trojanized UI-component package that, when required, downloads and executes a second-stage binary. The bootstrap code fingerprints the OS/architecture, then fetches a platform-specific payload over HTTPS from Cloudflare Workers endpoints oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, and oob-worker[.]cf99-9b3[.]workers[.]dev (paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe). If those fail it falls back to a DNS TXT-based channel using the domains c[.]sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, and net[.]dl[.]wel1[.]ru, reassembling base64-encoded chunks. The downloaded payload 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 Unix). A state file in the temp dir throttles repeat downloads.
