| fatzbitz 18. Nov 2006 | Enable Register Buttons --> it is enabled !!! |
|---|---|
| zairon Moderator 18. Nov 2006 | Fixed |
| Fergo Author 18. Nov 2006 | Thanks fatbitz for telling me this, and thanks to zairon for re-aproving the crackme so quickly. Hope this was the last error. |
| mucki 20. Nov 2006 | -Fish for serial or patch -> no keygen? patch = selfkeygen or goodboy jump? hm... i need 5 min to solve the tasks (without keygen / only phishing) i don't know if i understood something wrong |
| Mazrock 20. Nov 2006 | Fixed too, i'll send you my submission. i don't think i'll write a keygen... |
| Rufo 20. Nov 2006 | I've managed to remove the anti-debug and nag without problem. However, when I patch $6CD5 from 00 to 01 to enable the button, it seems to work but clicking the button does nothing. Same problem when enabled using vbreformer. Any ideas? |
| Fergo Author 20. Nov 2006 | Yes, but thats ok Rufo. I didn't used msgbox or something like that to make the crackme a little more difficult ( but it still very easy ). Thanks to all of you ;D |
| HMX0101 20. Nov 2006 | Search with HexWorkshop, this string "Register" and change the 12th byte to 01... |
| ProTreeBrain 21. Nov 2006 | Seems to be a nice crackme, I try it today. For Fergo: TRy make something in Assembler. If you try, you will see what I mean. After the 5 or 6 lines of code (algorithm to serial generate) you will totally confused, if you wont make a comments. Assembler is totally hard for physical-memory in my head. |
| ProTreeBrain 21. Nov 2006 | I need probably at least 20 TB(Tera-bytes) of memory. |
| BaKaE 21. Nov 2006 | 20 tera-byte om my good, thiz little vb-crackme needs so much?? i did a failure, proTreeBrain |
| Rufo 21. Nov 2006 | My submission sent. Note that if the name you enter is 4 characters or fewer, the register button appears to be broken (silently fails). Caused some confusion on my part... |
| Fergo Author 21. Nov 2006 | Thanks! Yes, there's a check for the lenght of the name. I've stared prgramming in asm a month ago, but i'm not ready to make a crackme on it :D |
| ProTreeBrain 22. Nov 2006 | For BaKaE: I do not need 20 TB to this crackme, I only explain the ASM programming to Fergo, because he saz that is a beginner. |
| movzx 22. Nov 2006 | ProTreeBrain : "I need probably at least 20 TB(Tera-bytes) of memory." you mean, it's your physical memory in your head right?? not in your PC.. :D |
| snorkelsnot 22. Nov 2006 | Well that was all pretty easy, except for enabling the button, for which i had to cheat using the comments here. Where can I find more info on enabling buttons? |
| nmr666 22. Nov 2006 | For HMX0101, how did you figure 01 out? it is the only bit that has got me |
| Fergo Author 22. Nov 2006 | The state of the button comes right after the button size and after a byte "08". The button size is easy to discover, but its a lot easier to search for the 08 byte after the "Register" string. |
| musically ut 23. Nov 2006 | Um.. A silly question, I guess, but does anti-debug mean that it can detect Olly, or does itextend to mean that it cannot be disassembled easily? I tried doing it with one and it failed. I wanted to know whether there is something wrong with the disassembler or is the program really "ANTI-debug"... |
| Rufo 23. Nov 2006 | I disassembled it with both Olly and IDA without problem; I think 'anti-debug' referred to the fact it detects that Olly is running. |
| SpiderZ 31. Oct 2009 | very old crackme but good. |
