| badmojo 26. Sep 2006 | Seems to have a small bug, when you click a switch it cannot find file "on.bmp". If this is intentional let me know... |

| geeko Author 26. Sep 2006 | oops, sorry i forgot something, I will upload again, thanx SORRY |
| zairon Moderator 26. Sep 2006 | No, my fault. I thought the solver should add the bitmap... |
| sd333221 26. Sep 2006 | Is brute-forcing allowed? I think i will try brute force it... 2^12 combinations is only about 4000 .... I will put in a colour check and let it run ;) Just want to know if it's allowed |
| BoR0 26. Sep 2006 | Normally, we can see that the author is drawing an Ellipse. Therefore set a breakpoint on GDI32.Ellipse, once we land there, press ALT+F9 (olly) to go to user-code, and before the Ellipse call we see a call that sets the color, here is where you should analyze. ...code... 0041F71F |. E8 6C050000 CALL distil.0041FC90 ...code... call elipse ...code... |
| geeko Author 27. Sep 2006 | @sd I think you cant brute force, but give it a try, i'm curious. Brute force is not a solution. @Boro LOL. I'll give u a hint: I dont use 'ellipse', but it is a Tshape. 'Ellipse' is called only by the system on 'repaint' event. |
| BaKaE 27. Sep 2006 | @ geeko did you reuploaded this crackme?? |
| geeko Author 27. Sep 2006 | Bakae yes, now it contains the bitmaps. |
| BoR0 27. Sep 2006 | geeko, and what do you think TShape is? Delphi is just another API-wrapper programming language. |
| geeko Author 28. Sep 2006 | @Boro, I meant Delphi calls 'ellipse' NOT the author. Thanx for your recommendations, but I think it's useless. @sd, after each combination u have to wait a little amount of time to see what happens. go on |
| sd333221 28. Sep 2006 | I bruteforced it! I got the combinations :-) But i am not allowed to post an video on how to bruteforce it! -.- I will see if i can solve it on my own :D |
| geeko Author 29. Sep 2006 | If your brute force is accepted by the moderators as solution, I promise I'll make another version with much more switches! |
| sd333221 29. Sep 2006 | It's not a solution ;-) I just did this for learning |
| zairon Moderator 29. Sep 2006 | @sd333221, you can post a video (I did the same thing with my last solution) but you have to explain what you did. Few phrases are not a solution. Do you really think a newbies learn something from the video? Sorry but I don't think... @geeko, we can accept a bruteforcer because when you release the crackme you only specify "no patch". We can't always ask the author for what we can/can't accept... If you have something else to ask me, feel free to contact me via pm. Please, leave this area for the crackme only. |
| geeko Author 12. Oct 2006 | the checking routine runs under am emulated processor. U have to reverse another kind of ASM |
| stars2000 28. Dec 2006 | Nice one geeko. different from others. I would like to see how you bruteforce very much, if you care to send a real video sd. |
| geeko Author 29. Dec 2006 | star, ask sd333221 |
| BaKaE 29. Dec 2006 | i believe hes is banned, coz hes never online :( |
| zairon Moderator 29. Dec 2006 | He's not banned... |
