    Again easy VB6 coding, easy upx packed (use -d option to unpack).. Also there is only one RULE: - no cracking/patching, just *fish* for it AND post here any feedback! This is my second fishme so dont be dissapointed if it's too easy, its good to practice, right :?) DOWNLOAD it here (only 5 KB) *there are many solutions possible* so keygening it will be very good thing to do. It is not hard! Have a nice day!

    The objective of this test is to identify you on the database server. You do not have the right of patcher the server. You will have gained when the message "CHEER..." is posted with the screen. Indince: BOF PS: This "pseudo" Server is only one simulation, do not hope to obtain interesting data:) HackMe.rar

    My first crack me and my "first" C++ app(I have made dlls before but not exe). http://www.mattsbox.co.uk/high6/Files/crackme1.rar crackme1.rar Have fun . If you think you have it check the hint first. Hint: The messagebox is a fake .(the correct password doesn't have a messagebox popup) Note: Not packed. Hint2: There are over 100 jumps and over 200 calls to assemble the password.
