| ProTreeBrain 21. Nov 2006 | Tommorow try crack it, but I dont see it very good for my success. It is not very interesting protection for me, but I try it. |
| geeko Author 21. Nov 2006 | Which protections do you like? |
| Zaphod 21. Nov 2006 | I found what color the squares should be, so it would be easy to patch the crackme, but that isn't allowed - and it wouldn't be much fun. Now I'm trying to find out in which order the squares should be pressed... |
| geeko Author 21. Nov 2006 | There could be more then 1 good color schemes. Give here an example. Also, there could be several solutions. I didn't test. And to be more chalenging, try to make the sqaures the same color! |
| geeko Author 21. Nov 2006 | Do you think you can solve it if I'd give you the portion of the source code which deals with the clicks without running it ?! :-)) I think I cannot :) |
| Zaphod 21. Nov 2006 | The one solution I have found is ten blue squares. First I arrived at that one by patching, later I was lucky enough to generate 10 blue squares by just playing around with the crackme. But of course I cannot repeat those lucky strokes now, so I'm trying to get an overview of what the different clicks do by looking at them with IDA's graphic view. As for the solving it without running it - I probably couldn't, but who knows :) |
| ProTreeBrain 22. Nov 2006 | I like more usual protections type such keyfile, serial ... |
| geeko Author 22. Nov 2006 | Right,I told you, probably there are more than one click combination. @Protree, I like unusual protection, coz' they are not so boring and not many people expects them. It's your chioce. There are some of my crackmes, than you'd maybe like. Give them a try |
| Zaphod 22. Nov 2006 | geeko, isn't this: 004501EA . C705 383C4500>MOV DWORD PTR [453C38],0FF00 004501F4 . C705 383C4500>MOV DWORD PTR [453C38],0FFFF00 a small mistake? Shouldn't one of the [453C38]'s have been a [453C3C]? |
| geeko Author 22. Nov 2006 | You are right, It's a mistake not so important. But You must leave it as it is for the program to work as expected. Perhaps it doesn't matter. |
| Zaphod 22. Nov 2006 | I have a solution now - will write a little about it... |
| geeko Author 23. Nov 2006 | how did you find it |
| Zaphod 23. Nov 2006 | I'll submit a tutorial today or tomorrow... |
| movzx 24. Nov 2006 | things left only for a tuts.. nice crackme.. reminds me on GridMaker.. :D btw.. your hint works.. thanks.. :D |
| geeko Author 24. Nov 2006 | I told, there may be more solution. |
| geeko Author 30. Nov 2006 | Zaphod. LOLOs very nice. Nicer than I expected. You found a much shorter code than the one I worked on: 348216952083686 thanks good job, Zapho |
| Zaphod 30. Nov 2006 | Thanks, geeko, but you have to tell me - what does LOLOs mean ? |
| geeko Author 01. Dec 2006 | plural of Laughing Out Loud Out |
| Zaphod 01. Dec 2006 | okay, thanks - I only knew LOL... |
| geeko Author 03. Dec 2006 | LOL. If you want more than LOL than you may LOLOLOLOLOLOLOL. :) |
