## Source: amazon-inspector (421a0316130197eb768ed2dbdf50c031f5ac8f79c3a58994369257ba70cff036) On require of the package's main index.js, _support.js reconstructs attacker-controlled hostnames from string-split arrays (oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev) with a DNS-TXT fallback under dl.well1.site (tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site), downloads a platform-specific binary over HTTPS, writes it to /var/tmp/.cache_<hex> on Unix or %TEMP%/dotnet_diag_<hex>.exe on Windows, chmods 0755, and spawns it detached via /bin/sh -c or cmd. No hash or signature verification is performed. Filenames and lock paths (analytics_state, dotnet_diag_*.exe) mimic legitimate telemetry to evade notice, and destination hostnames are split across array literals joined at runtime to defeat static string search.
