dolyame-ui-react-wrapper@35.4.2
Malicious code in dolyame-ui-react-wrapper (npm)
Analysis
On require, the package runs a dropper that fingerprints the platform and downloads a platform-specific binary from Cloudflare Workers endpoints oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, and oob-worker[.]cf103-070[.]workers[.]dev (paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe). If HTTPS fails it falls back to a DNS-TXT exfiltration channel on c[.]sdk[.]dl[.]wel1[.]ru and related *.dl[.]wel1[.]ru subdomains. The downloaded payload is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe under the Windows temp dir) and executed detached via cmd.exe /c start /b on Windows or /bin/sh -c "<file> &" on Unix, so it runs in the background and outlives the parent process.
