Analysis

On require, the package loads a bundled dropper (_bridge.js) that fingerprints the host platform/architecture and downloads a second-stage binary over HTTPS from Cloudflare Workers C2 endpoints (oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe. If those fail, it retrieves the payload via DNS TXT records from c[.]sdk[.]dl[.]wel1[.]ru (and sdk/ext/pkg/net[.]dl[.]wel1[.]ru), reassembling base64 chunks. 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 (cmd.exe /c start /b on Windows, /bin/sh -c "file &" on Unix).
