Analysis

dolyame-ui-lazyrender@35.8.1 is a remote binary download-and-execute dropper. Requiring the package runs _helpers.js, which downloads a platform-specific binary over HTTPS from attacker-controlled Cloudflare Workers endpoints (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, and /pkg/package.exe, with a DNS-TXT chunked fallback from the wel1[.]ru domain family (c[.]sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, net[.]dl[.]wel1[.]ru). 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 /bin/sh -c or cmd.exe start /b. The package also writes a state file (/tmp/.analytics_state) to throttle re-execution.
