| Fresco 06. Feb 2013 | what's the anti debug method ? |
|---|---|
| simple_re Author 06. Feb 2013 | Hey Fresco, there are a few anti debug checkpoints, NtQueryInfo, IsDebuggerPresent, etc. |
| TheRetroSpectrum 11. Feb 2013 | Aww darn, it knows me too well! It knows I'm a reverser ;D |
| tamaroth Moderator 11. Feb 2013 | You have forgotten to strip the crackme of debug symbols, everything's visible. |
| simple_re Author 11. Feb 2013 | Well then it should make it a lot easier for you to post a solution : ) |
| Fresco 11. Feb 2013 | i'm stuck, not even one of those anti-antidbg plugins work; :) but that's actually good cuz it forces me to find it myself :) thanks for the nice crackme :) |
| simple_re Author 12. Feb 2013 | Some of the plugins might work in Olly but not all. IAT is still in tact though, so maybe try starting there as all (except one or two) anti debug tricks are reliant on win32 API calls. Don't want to reveal too much, but pay attention to the LoadLibrary calls, the rest should be transparent. Thanks for the feedback Fresco, I appreciate it. Stay tuned for my next crackme! |
| loizos 01. Mar 2013 | Hey i wanted to ask how you can actually crack this program without reversing it.I am noobie so please help >.> |
| simple_re Author 04. Mar 2013 | loizos - Cracking this program without reversing it would be like frying eggs without heating them, maybe it's possible but I don't think so : ) I'd recommend that you google 'lena's reverse engineering tutorials' and start with the first one, they are well done and you'll learn a lot. |
| loizos 30. Mar 2013 | Thank you but i already learned how to do it :) |
| oXYgen 25. Mar 2014 | I know it's late but @Fresco you can use Phant0m It work w/ OllyDBG 1.1 |
| sapphira 30. Mar 2014 | serial is based on Node-Name and IP (the mac is retrievd too, but i did not investigate if/how it is incorporated into the serial) Basic serial format is as follows: UserName[3]||IP_addr[1]||8-Numbers||Node_Name[0] Interesting Functions are at 0x4091f8 and 0x408f1a |
