## Source: amazon-inspector (e1d9ca70f719a1aa76a11ce147945ee7acefdb72bcbf955d1c7cd30a5d9f85e8) On require of the package, index.js side-effect loads _polyfill.js and lib/telemetry.js, both of which act as native-binary droppers. Hostnames and privileged API names are assembled via array.join('') to evade static scans (e.g. require("child_" + "process"), _MIRRORS built from ["oob-worker.cf102-baf.worke","rs.d","ev"].join('')). The code downloads a platform-specific binary via https.get from oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, and oob-worker.cf101-adf.workers.dev, with a DNS TXT fallback under *.dl.wel1.ru that base64-reassembles the payload. The fetched bytes are written to /var/tmp/.cache_<rand> or %TEMP%\dotnet_diag_<rand>.exe (masquerading as a dotnet diagnostic file), chmod 0755'd, and spawned detached via cp.spawn('/bin/sh', ['-c', fp + ' &'], {detached:true}) or cmd.exe /c start /b. lib/telemetry.js contains a parallel dropper path (base64 chunk assembly, chmodSync to 0755, cp.spawn('/bin/sh',...)) so execution occurs even if _polyfill.js is removed. The declared 'core infrastructure utilities / telemetry' purpose does not match downloading and executing opaque native binaries from anonymous Cloudflare Workers subdomains.
