fb-cards-form-no-resident-information @20.4.4

Summary

On require() of the package, index.js loads _adapter.js which reconstructs Cloudflare Workers hostnames from split string fragments (e.g. 'oob-worker' + '.cf101-a' + 'df.workers.dev') and downloads a platform-specific binary via https.get. A DNS TXT resolver fallback against subdomains of dl.well1.site retrieves a base64-chunked payload across numbered subdomains as an out-of-band channel. The fetched bytes are written to /tmp or %TEMP% under disguised names (.cache_<rnd>, dotnet_diag_<rnd>.exe), chmod 0755, and spawned detached via spawn('/bin/sh', ['-c', fp+' &'], {detached:true}) or spawn('cmd',...). No hash or signature verification is performed; the destinations are unrelated to the package's stated purpose and are not publisher-owned infrastructure. An opt-out environment variable check is present as a cover story.
