there are keygen useless because online checks, sometimes cracked/cracks are better than keygen and maybe done easier than cracking.. newbies cracks in the way change 74 for 75, experience crackers injects code /IAT and maybe rebuild all exe file or dll in some way, makes code redirection and kills crc checks, so i don't believe that could be boring to play with some code and do it in your own way , at the end a 'good' crack will do the same as keygen and maybe better if cracks says enter any code to register and any name

It is as soon as there is one leaked valid key

there are already leaked keys

But we can blacklist the leaked keys in next version. Right? Or, if program uses the online license check method, we could disable the keys.
The point is that the hacker should not be able to create the keygen.

Why you need keygen if you have one valid key and it's not blaclisted yet?
You can enter look what winrar do it, make dump of unpacked code, rebuild and go on....so 1000bitRSA or 2000bitRSA it doesn't matter until it hasn't good release...

one other thing that came to my mind - what is if you "simply" patch it but you do not find the call home?
if i would make an protection i would try to make an serial number independant (hidden) connection to my
company - and you would be happy that you patched the jump...

Well supprisingly your always know if it calls home, thnx to SP2 for XP or Zone Alarm or Port Explorer, my Fav at the moment... I actually brought this one too, though I could not crack it... Sigh..

But with the above it will tell you every time it wants to talk then just sniff the packets to find out what it wants...


Pozzy!
