| Download FuelVM-Keygenme.zip, 38 kb (password: crackmes.de) Browse contents of FuelVM-Keygenme.zip This is a fairly straight forward VM keygenme. If you have not dealt with VMs before it might be a little harder than a 2. Let me know if there are bugs.

| electron 03. Apr 2012 | hey, I’ve managed to find a serial manually by looking at cmps, but i can’t find the generation of the values that are in the cmp. can you write a tut? (I’m talking about this cmp: 00401935 |. 38D0 CMP AL,DL that compares a char from the password to another char that was somehow generated according to the username) |
| daybreak Author 06. Apr 2012 | Hello! Check out rdtsc.net for the solution. I saw your comment on my blog first so I'll paste my response below: Check out 401271 where the username is first distorted. From there, the functions within the VM are executed where the distorted username is given as input and the resulting bytes are compared against the key (one byte at a time) which is DL in that CMP. Send me an email if you would like the src. |
| daybreak Author 13. Apr 2012 | That is one hell of a solution. I'm honored, thank you slackspace nice job! |
