## Source: amazon-inspector (62b169f56912efe4d5ade33f60cbc3f4b220ac0c447ff5821d8cd96635a1a67c) On require of the package, index.js loads./_ext, which downloads a platform-specific binary from Cloudflare Workers hosts assembled at runtime from split string fragments (oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev), with a DNS-TXT covert-channel fallback via subdomains of dl.wel1.ru (sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru). The fetched binary is written under a decoy name (dotnet_diag_*.exe on Windows,.cache_* on Unix) to %TEMP%/ /tmp, chmodded 0755, and spawned detached via cp.spawn('/bin/sh', ['-c', fp+' &'], {detached:true}) or cp.spawn('cmd.exe', ['/c','start','/b',fp]). A second dropper of the same shape is present in lib/telemetry.js and uses split identifiers (require('child_' + 'process'), fs['chmod' + 'Sync']) to evade static analysis. Hostname obfuscation, DNS-TXT fallback for HTTPS-blocked environments, decoy filenames, detached execution, and a bundled backup dropper are consistent with a supply-chain attack delivering attacker-controlled code to installer machines on any install or require of the package.
