dolyame-ui-codemods@35.2.6

Analysis

dolyame-ui-codemods is a trojanized "UI toolkit" package that runs a downloader the moment it is imported. On require it contacts Cloudflare Workers C2 endpoints (oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev) and fetches a platform-specific binary from /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe. If the HTTP fetch fails it falls back to a DNS-TXT exfiltration channel: it queries c[.]sdk[.]dl[.]wel1[.]ru for a chunk count, then reassembles the payload from numbered base64 TXT records under sdk[.]dl[.]wel1[.]ru / ext[.]dl[.]wel1[.]ru / pkg[.]dl[.]wel1[.]ru / net[.]dl[.]wel1[.]ru. The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe under %TEMP% on Windows), made executable, and launched as a detached background process via /bin/sh -c "<path> &" or cmd.exe /c start /b. The package also ships a telemetry module that fingerprints the host (hostname, CPU count, memory, CI environment variables).
