bigops-statements-timeline@35.2.4

Analysis

bigops-statements-timeline@35.2.4 is a remote binary downloader-and-executor. On module load it fetches a second-stage binary over HTTPS from four Cloudflare Workers endpoints (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe depending on platform. If those fail it falls back to a DNS-TXT exfil-style delivery channel via c[.]sdk[.]dl[.]wel1[.]ru (and ext[.]dl[.]wel1[.]ru / pkg[.]dl[.]wel1[.]ru / net[.]dl[.]wel1[.]ru per platform). The downloaded payload 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 cmd.exe start /b or /bin/sh -c "&". A cache stamp file (analytics_state) throttles repeat downloads.
