Intro:The FBI has intercepted a program which contains important information. The program needs a code to give the information free, but the FBI and CIA are clueless and has asked you, as a professional cracker, to get the information from the program.
The Story of the FBI:
A Russian maffia group who call them selfs Brevihock are planning an attack on the american ambasy in Berlin (Germany). Atleast that is what the cought suspect says. He says it has something to do with a recently researched technology in a Russian laboratory about radio-active radiation. This is all the suspect swears to know. He does not know when the attack is going to take place. The Russian goverment is clueless too because all of the research institutes have to report their foundings to the goverment but nothing of this has been reported, and the Russian police is drowning in the loads of paperwork to go through, seeing if they can find any of this in the research documents taken from the laboratories.
The FBI can not get their hands on the documents because Russia wont cooperate by sharing the documents, and there by sharing all of their researched technologies of the last couple of years.
The FBI has managed to crack the email of the suspect though. This resulted in some information about corrupted professors on the payroll in Russia and the role of the suspect in this case.
The suspect needed to provide some goods to the laboratory so they can finish the weapon.
In one of the emails there was an applications (windows based) which should contain the exact location of the laboratory. The application needs some kind of code. How hard the FBI tries, the suspect claims to have forgotten the code.... We know that it is not the truth but more he wont spit.
Crack the application and find the location.
** Tested on Windows Xp and Vista **
Once you have the location, check it out, and you will know if you have the correct location or not. If you doubt anyway then PM me.
If you needs tips, then post a comment.
- Add 2 new sub menu-items under the menu-item 'File'.
- Call one of them 'Info'.
- The other one 'hide'.
- Add a seperator between 'hide' and 'exit'.
- Make the 'Info' button display an alert(OK button) with the text "Net Force Reverse Engineering Challenge".
- Disable the 'hide' button so you can't click it anymore and it's gray.
- Change the text "Hello World!" into "Reverse Engineering is cool!".
- Write a full tutorial on how you did it.
- Patch hello.exe and make everything work.
Tools to use:
- Dissambler (i.e. ollydbg)
- Patcher (or HEX editor / Ollydbg)
- HEX editor
- The use of a Resource Editor is strictly forbidden!!!
I have made a new, harder CrackMe. Were you challenged by the first one? Or was it a piece of cake? This one is a bit harder.... it is NOT packed though.
Rules: no rules
Yeah that is right, with the first CrackMe patching was a quiete lame solution. This one is a little bit based on the previous one, it also uses an encryption. This time the result of the encryption is more important! Patch what you want with this one and good luck!
You have to reveal/find the secret text. If you have found the secret text (or you think you do) go to http://members.lycos.nl/wietsite/fp.php
Fill in you secret as fp.php?x=secret_text
The php script will say to you if you have the correct text or not....
File:Download the CrackMe
Goodluck and Enjoy,
P.S. If you managed to crack this one, I really like to know how! PM me or leave a comment if you succeed (or if you need a tip)!
Some of you might have heard from me ([topic:]http://www.reversing.be/forum/viewtopic.php?t=627[/topic:]). And thereby know that I am not much of a coder in masm32 (asm).
But I made a crackme....
You have to find the password
Patching is ofcourse possible but that is not the goal of this crackme.
This crackme has a few anti-debug tricks.
The file is not packed (I don't even know how to).
Do you take the challenge to crack this app made by a Noob ;) ??
If you managed to crack it, mail the correct password to firstname.lastname@example.org
