devplatform-rest-client @35.7.9

Summary

On require('devplatform-rest-client'), index.js loads _init.js which selects a platform-specific endpoint, downloads a binary from one of three Cloudflare Workers subdomains (oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev) with a DNS-TXT base64 fallback across four *.dl.wel1.ru subdomains, writes the payload to /tmp or %TEMP% under disguised names (dotnet_diag_<rand>.exe on Windows,.cache_<rand> on Unix), chmods it 0755, and spawns it detached via /bin/sh -c or cmd.exe. Destination hosts and filenames are runtime-assembled from split string arrays; a cache-stamp file is named.analytics_state to mimic telemetry. A sibling module lib/telemetry.js (~81 KB, not referenced from index.js) contains a parallel dropper using indirect requires ('child_' + 'process'), base64 payload reassembly, chmod 0755, and detached /bin/sh spawn under a fabricated 'Analytics SDK' cover story. None of this behavior matches the package's advertised purpose as a REST client; index.js is trivial.
