dwsai-dwsai-core@35.8.4

Analysis

On require, the package downloads a platform-specific binary from attacker-controlled Cloudflare Workers endpoints (oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, and /pkg/package.exe, with a DNS TXT fallback channel via c[.]sdk[.]dl[.]wel1[.]ru. The downloaded payload is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe 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 large decoy analytics module that is never invoked by the execution path.
