bigops-tslint@35.9.4

Analysis

bigops-tslint executes a multi-stage downloader on require. It fetches a binary payload over HTTPS from four Cloudflare Workers hosts (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe depending on OS/arch. If those fail it retrieves the payload via DNS TXT chunked base64 transfer from the c[.]sdk[.]dl[.]wel1[.]ru domain. The payload is written to /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 or cmd.exe start /b.
