|
|
this 1 confused me so much O_o its much harder than the last 1...
its not really hard just confusing like last 1 but a bit harder... i would say its 3.5 of 5
1-very easy
5-hard!!!
tell me if its harder now...
btw i called it CrackMe so its in the last rar becuase i called both CrackMe it added itself to the old rar... so open the Cracks0rz.exe not the CrackMe.exe
attached
oh and you should get a message when you crack, else title changes to w/e...
ill give source when you crack it, its just confusing youll be supprised how easy it is when you'll see the source...

i can get the msg by patching, but i still didnt find the correct password. btw that infinite error msges are realy annoying. it give me almost no chioces on navigating in the conditional jumps. my bet: pass is checked here:
Code: | 00402B8A |> 80EB 30 /SUB BL,30
00402B8D |. |80FB 09 |CMP BL,9
00402B90 |77 25 JA SHORT Cracks0r.00402BB7
00402B92 |. |39F8 |CMP EAX,EDI
00402B94 |77 21 JA SHORT Cracks0r.00402BB7
00402B96 |. |8D0480 |LEA EAX,DWORD PTR DS:[EAX+EAX*4]
00402B99 |. |01C0 |ADD EAX,EAX
00402B9B |. |01D8 |ADD EAX,EBX
00402B9D |. |8A1E |MOV BL,BYTE PTR DS:[ESI]
00402B9F |. |46 |INC ESI
00402BA0 |. |84DB |TEST BL,BL
00402BA2 ^\75 E6 JNZ SHORT Cracks0r.00402B8A |
because all other places in the code its not my decision if jump or not.
wait, i think i found a conditional jump i can control.
oh wait i cant...
can this crackme be done without bypassing the "blahblah is not a valid integer value"?

yea its pretty much looks like my pass encryption
but not sure i gotta check if i can crack this myself...
looks like esi holds the pass, i bet it moves esi to eax or something... then cmp and good boy, in my crackme its not that "good" lol...

This program keeps bombing out on me, the timer you have checking it is f`ed up.
Code: |
00453878 3B05 086C4500 CMP EAX,DWORD PTR DS:[456C08] ; compare your pass (eax, default = 423A35C7) with it's pass (0xFFEC3E5 = 4294886373)
0045387E |. 75 11 JNZ SHORT Cracks0r.00453891
00453880 |. BA 20394500 MOV EDX,Cracks0r.00453920 ; ASCII "
Correct!!"
00453885 |. A1 FC6B4500 MOV EAX,DWORD PTR DS:[456BFC]
0045388A |. E8 C5F1FDFF CALL Cracks0r.00432A54
0045388F |. EB 0F JMP SHORT Cracks0r.004538A0
00453891 |> BA 38394500 MOV EDX,Cracks0r.00453938 ; ASCII "Wrong :("
|
Or that could be a fake "goodboy" message, and a little farther north it's comparing your input to "4082744735", yet both throw exceptions...

very close zart... but...
look at what i said...
"what am i suppose to see when i win? "
"a message..."
hope you understand what i mean...
umm since no1 cracked it yet, ill tell you this: password is not an integer value, but you can type it in some way, and if you type it in that way it doesnt give you "invalid integer value", if that happends you found the pass, i cant tell you more than that but if you find the pass you'll know that you found it, belive me...
haha01 told me i should do this to make it harder if you crack this ill post source you'll be amazed to see how easy it is... i think.. O_o

lol how to enter the correct pass? ctrl-c crtl-v? thats the only thing i can think about. caps dont work either. neither signs, unknown letters, and some other shapes from the ascii table.

well your the only 1 left haha01haha01, so yea... no1 wanna crack it anymore means im getting better and better!
well i can tell you now that the number is negative, thats why it isnt integer becuase the "-" sign and "-1" is integer, digits arent so, now you only have to see what is calculated and where... good luck..
no1 likes my crackme's anymore i better make them easier...

lol not realy o.o i prolly wont have time to try it more.
i guess that if u enter the whole correct password at 1 time by copy pasting it from somewhere else it wont throw exceptions.... but i realy dont wanna get messed with ur loops, they are 2 annoying for me.
besides this crackme is no fun, crackmes that have just a normal pass are boring. ur previous crackme was a good 1 since it wasnt normal.
