Real cost of buying the extension: .
Scattered across torrent sites, shady Telegram channels, and blogs with names like "nulled101[.]com" or "freeM2modules[.]ru," you will find promises of $500 extensions available for immediate download—completely free. The term "nulled" means the software has been hacked (cracked) to remove licensing checks, domain restrictions, and trial limitations.
Once uploaded, the attacker can simply visit: https://yoursite.com/?nulled_cmd=execute&cmd=cGhwaW5mbygpOw== (base64 for phpinfo(); ) and they have full environment access.
