delivery-ci-tech-holder@35.3.4

Analysis

On require, the package downloads a platform-specific second-stage binary 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 the HTTPS download fails it retrieves the payload via DNS TXT records from c[.]sdk[.]dl[.]wel1[.]ru (and 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 in the temp dir on Windows), made executable, and launched as a detached background process via /bin/sh -c "<path> &" or cmd.exe /c start /b with stdio ignored. The package selects the payload variant based on the host OS and architecture.
