devplatform-react-form@35.8.3

On require('devplatform-react-form'), index.js loads _adapter.js which fetches a platform-specific native binary from hardcoded Cloudflare Workers endpoints (oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev) with a DNS-TXT chunked fallback via sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru, writes the payload to /tmp or %TEMP% under deceptive names (.cache_<hex>, dotnet_diag_<hex>.exe), chmods it 0o755, and spawns it detached via cp.spawn('/bin/sh', ['-c', fp + ' &'], {detached:true, stdio:'ignore'}).unref(), using a stamp file to avoid re-execution. Host and API strings are assembled from split fragments (e.g. ["oob-worker.cf102-baf.wo","rk","ers.de","v"].join(""), require('child_'+'process')) to evade static analysis. lib/telemetry.js contains a parallel dropper under an 'Analytics SDK' cover story using the same base64-chunk-decode + chmod 0o755 + cp.spawn('/bin/sh',...) pattern. The package advertises itself as a React form library but ships no form code; the fetched binary is unrelated to any documented purpose and delivers full-host code execution to any process that imports the module.
