| costy Author 11. Jul 2008 | @xylitol What do you mean with "i'm surprised by the buton" Problem with anti-debugging? |
| DigitalAcid 11. Jul 2008 | I get an exception in Olly, more than 1, I think =). Probably because it's somehow dividing by zero. Else, I get runtime errors, etc. O.o. |
| costy Author 11. Jul 2008 | @DigitalAcid It works correctly if you dont run a debugger :-))) |
| MACH4 11. Jul 2008 | Ha! Nice one costy! interesting method, if I'm right then 'Needs special knowledge' certainly applies to this one. Trying to completely RE it, need to do some reading! |
| costy Author 11. Jul 2008 | @MACH4 I'm very very sad. :-( So can you reverse it? I hoped this crackme was more difficult then my last one! |
| MACH4 11. Jul 2008 | @costy, Don't be sad! I haven't RE it completely yet, almost there! and it IS more of a challenge than the last one. Ok I won't give any hints! Don't want to spoil it for others! |
| costy Author 11. Jul 2008 | OK I dont want to help you becouse you resolved my last one in a second. Have you ever seen the anti-dbg I used?? |
| MACH4 11. Jul 2008 | Yes, nice:-) Added text here for the post to be accepted |
| costy Author 11. Jul 2008 | It's strange you have already seen it... It's really rare. Does the crackme work inside the debugger now?? |
| MACH4 11. Jul 2008 | Well, yes it works in the debugger, although I have a small item (PTR) to find and correct... |
| costy Author 11. Jul 2008 | PTR???? What is it? |
| Bispoo 11. Jul 2008 | Solved, button enabled, :) nice crackme, a little harder this time too, took an additional 5 minutes :p |
| Xspider 11. Jul 2008 | i think i will try it :D |
| costy Author 11. Jul 2008 | @Bispoo Only 5 minutes?? Are you sure?? |
| Bispoo 11. Jul 2008 | Sent u a PM costy. |
| costy Author 15. Jul 2008 | @Bispoo Nice Solution. Anyway It's better to explay the outputdebugstring trick. outputdebugstring let the programmer to display a string in the debugger. it's prototype is void OutputDebugString (char *string1);. If you declare it as int int OutputDebugString (char *string1); it will return 1 if there isn't a debugger. A value different then 1 if the debugger is present. Nice anti-debugger. Anyway I hope that somebody will invent a plugin for olly that remove this problem. Bye |
