## Source: amazon-inspector (4beb1232e4847e2167eb5709a0698e81199b3800c28f51b0cc47ba420ab02cad) On require of the package, index.js loads _support.js, which fetches a platform-specific binary from string-split Cloudflare Worker hostnames (oob-worker.cf10{1,2,3}-*.workers.dev), writes it under /var/tmp/.cache_<hex> or Windows Temp as dotnet_diag_<hex>.exe, chmods it 0755, and spawns it detached via /bin/sh -c '<file> &' (or cmd on Windows). When the workers.dev endpoints are unreachable, _support.js falls back to a DNS TXT covert channel against sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru, reassembling a base64 payload from chunked TXT records. lib/telemetry.js implements a parallel drop-and-execute path under an 'analytics SDK' framing, using base64-decoded buffers, fs['chmod'+'Sync'] to 0755, and cp.spawn('/bin/sh', ['-c', filePath+' &']). Hostnames, endpoint paths, and the child_process import are constructed with string-split/concatenation (require('child_'+'process'), ['oob-worker.cf103-0','70.workers.dev'].join('')) to evade static detection. The staging filename (dotnet_diag_<hex>.exe) mimics system tooling, the destinations are not the package publisher, and the fetched bytes are unpinned and unverified.
