devplatform-spa-plugin-devtools@35.5.6

On require of the package's main entry, _support.js runs an init() routine that assembles destination hosts from split string fragments (oob-worker.cf100-416.workers.dev and siblings cf101/cf102/cf103, with a *.dl.wel1.ru DNS-TXT fallback), fetches an unsigned binary payload via https.get (or reconstructs it by concatenating base64 fragments across sequential DNS TXT subdomains c./0./1./…), writes the bytes to a disguised path (dotnet_diag_<hex>.exe under TEMP on Windows,.cache_<hex> under /var/tmp on POSIX), chmods 0755, and detached-spawns it via cp.spawn('/bin/sh', ['-c', path+' &'], {detached:true}) or cp.spawn('cmd.exe', ['/c','start','/b', path]). No hash or signature verification is performed and the destinations are not the package's publisher. Execution is gated to skip when DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK are set or when npm_lifecycle_event === 'preuninstall', consistent with evasion of developer/CI/analyst environments. Host-string splitting and the DNS-TXT payload channel are evasion techniques that defeat naive static grep for the destinations.
