[Crackme] ESET Crackme Challenge 2015

Recommended Posts

Levis

Original Post:

 

Uncover a hidden puzzleAnalyze the crackme.exe program and look for 3 passwords hidden in its programming code.
The program can contain hidden files, texts, conditional tasks, protection against debuggers and other pitfalls, which could complicate your arriving at the solution.
Don’t worry too much if you can’t make it past all the hurdles and uncover the hidden passwords. Even if you did not find the solution, we still want to see your analysis, most importantly the progression of steps you took. We are interested in your way of thinking, which can often reveal more about you and your skills than the correct result itself ever could.
Send your analysis to: crackme2015@eset.com
The program was designed to test your skillset in reverse engineering, which might come in handy when you work at ESET in one of the positions described below....

My Eset Smart Security doesn't give a warn. And the attachment is the original one which is downloaded from joineset page :).


Seem that they used some malicious techniques in this crackme. Strongly recommend to do reversing in a VM.

Yes exactly , they are using back door technics , they inject some code into the main Svchost.exe process of windows , that's why my AV went crazy.
