Hashcat and itunes backup 10+ (-m 14800) vs itunes backup recover tools

[cippo]

I want to ask you guys something,

why some tools, like iphone backup unlockers, can try something like 4k pw's/second  and with hashcat only 0 or 1 H/second? 

Thank you!

There's no software which can crack PBKDF2-HMAC-SHA256 faster than hashcat.

so you think it's a fake program? it seems to work pretty fast
