Hey guys its me again with my Fifth version of my crackme's. This crackme should be the hardest. (emphasis on "should").
OBJECTIVES
1.Crack it and post a picture of it cracked.
2.If you didn't crack it by finding a "ID" and "PW" do so and post the ID and PW
3.Find the (not so) Hidden messages . . . there are from 5 to 10
(you might have to decript some/rearange letters)
4.Explane how you did all of this.
5.Have fun? I really don't know how to make "Fun" crackme's soooo.
(P.S. My Crackme only uses typable letters for Password)
Its been a week how is it going? It seems like everyone is dead on the Crack me fourm. Are yall all right?
Credit to coder sal for "hidden messages" idea

All you did was patch the bad message to display the good one. That really isn't cracking it.
Not sure if this is the correct congrats but:
"Conratujlation!!! I can't spell!"
Method of obtaining this screen:
Enter anything for the name and the pass. In olly break here:
| Code: | | 00403BF5 /0F84 37470000 JE a.00408332 |
This line is for the length compare. (Just be sure to enter something longish to get it to pass this, no need to patch it.)
The next part is a few additions and compares. I didn't bother digging into this to see what it's for, I just patched it instead:
| Code: | 00403C03 FF15 BC104000 CALL DWORD PTR DS:[<&MSVBVM60.__vbaStrCo>; MSVBVM60.__vbaStrCopy
00403C09 0FBF43 34 MOVSX EAX,WORD PTR DS:[EBX+34]
00403C0D 48 DEC EAX
00403C0E 0F84 71170000 JE a.00405385
00403C14 83E8 02 SUB EAX,2
00403C17 0F84 1E170000 JE a.0040533B
00403C1D 83E8 02 SUB EAX,2
00403C20 0F85 23170000 JNZ a.00405349
00403C26 8B13 MOV EDX,DWORD PTR DS:[EBX] |
NOP out the jumps in there or patch them to not work. Easier to nop. Once thats down scan for __vbStrcmp like any other VB crackme. Once found you will find it here:
| Code: | | 00405234 FF15 68104000 CALL DWORD PTR DS:[<&MSVBVM60.__vbaStrCm>; MSVBVM60.__vbaStrCmp |
Look at the buffers being compared. (EAX = your pass, ECX = real pass)
Working set of username/pass:
Name: aaaaaaaaa
Pass: _Zhi 0Zo0g
