Modem Booster 2.4
Type : Boost your
modem
Protection : Serial
Tech : Patching
Crack : This program has a peculiar behaviour .... false S/N calculation
..and if we
enter that S/N it will lead to page fault .... never mind this shit can be easily
patched.
Use w32DASM and search for string "Unregistered version" shown in
splash screen :)
We can find many such reff and just look above that code .... you can see this
call ..
0x401AE0 CALL 423290
0x401AE5 CMP EAX,01
0x401AE8 JNE 401B4A .... JUMP TO "Unregistered version"
CALL 423290 is our attack point ... it should always return EAX = 01
Let us go inside and look where EAX is cleared .....
Inside CALL 423290
0x4232CA JZ 4232D2 | 74 06 OFFSET = 232CA
0x4232CC XOR EAX,EAX | 33 C0 ..... SHIT !!!
Patch :
So we must change above code to like this ...
0x4232CA XOR EAX,EAX | 33 C0 OFFSET = 232CA
0x4232CC INC EAX | 40
0x4232CD NOP |90
