Summary
Malicious code in cards-forms-credit-clone (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (2cf698916c071bb43228f0e40bbb5fc10c2c35c495e091c0b3d1cf1c10e8eb26)

On require('cards-forms-credit-clone'), index.js loads compat.js which downloads a platform-specific binary from obfuscated Cloudflare workers.dev hosts assembled at runtime via string-split concatenation (e.g. ['oo','b-worker.c','f101-adf.workers.dev'].join('')), with a DNS-TXT base64 fallback resolver at sdk.dl.wel1.ru. The fetched binary is written to /var/tmp or %TEMP% under disguised names (.cache<hex> / dotnetdiag<hex>.exe), chmod 0755, and spawned detached via /bin/sh -c or cmd.exe. No pinning, no hash or signature verification; comments frame the behavior as 'analytics'/'telemetry'. Hostname fragmentation and DNS-TXT covert-channel resolution are evasion patterns unrelated to the package's advertised 'cards forms' purpose. Any installer that requires this package is subjected to remote code execution under attacker control.
