| Just remove it. This crackme doesn't work. Added the DLL and still crashes |

| It's not a buffer overflow as someone said below! But a crack-me and indeed you can use conditional debuggers to avoid some protections! Glad you like this one! |
==> |
| To bypass for example isdebuggerpresent without patching you can use conditional breakpoints for example, great job madlogik! |

Good job mate, now go keygen me.

There is nothing to keygen here. key is hardcoded |

Does not check for size, smaller or larger than, so some of the explainations here are wrong.

Here is the VM detection for VMWare used on this crackme:
All the protections on this crackme were implemented in a way that could be bypassed by setting as in example in IDA something like: SetRegValue("ZF,0x1/0x0)
__try
{
__asm
{
push edx
push ecx
push ebx
mov eax, 'VMXh'
mov ebx, 0 // any value but not the MAGIC VALUE
mov ecx, 10 // get VMWare version
mov edx, 'VX' // port number
in eax, dx // read port
// on return EAX returns the VERSION
cmp ebx, 'VMXh' // is it a reply from VMWare?
setz[rc] // set return value
pop ebx
pop ecx
pop edx
}
