Analysis

delivery-ci-dpat@35.1.5 is a multi-stage dropper. Requiring the package executes _platform.js, which downloads a platform-specific binary from Cloudflare Workers C2 hosts (oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev) at path /pkg/package (or /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe), with a DNS-TXT covert-channel fallback from *.dl[.]wel1[.]ru (c[.]sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, net[.]dl[.]wel1[.]ru). The downloaded binary is written to /var/tmp (or %TEMP% on Windows) as a randomly-named .cache_<hex> / dotnet_diag_<hex>.exe file, made executable, and launched detached via /bin/sh -c or cmd.exe /c start /b so it outlives the parent. The package also ships an 81KB decoy analytics-SDK module (lib/telemetry.js) to mask the dropper.
