Ideally, for creating 3d animated videos one would need an expensive 3d modelling tool and of course knowledge on writing scripts. This might be a laborius process which requires skill and practice which stops from a normal man to create one. But times change, and we have an online 3d animation creator which can be used to create and publish our movies in matter of seconds.

Xtranormal is an online application which turns your imagination to life. Creating animations with Xtranormal is very easy and can be accompolished in four simple steps.

1. Pick your scene (Backgrounds, Music, Actor Skin etc)
2. Type the script (Not the ‘scripts’ in programming terms, here we mean dialogues)
3. Add actions and sounds (Just drag-n-drop)
4. Publish & Share ( In video sharing sites like YouTube or in Xtranormal catalog)

Schmich’s June 1, 1997 column began with the injunction to wear sunscreen, and continued with discursive advice for living without regret.

Lyrics

Ladies and Gentlemen of the class of ’99
If I could offer you only one tip for the future, sunscreen would be
it. The long term benefits of sunscreen have been proved by
scientists whereas the rest of my advice has no basis more reliable
than my own meandering
experience…I will dispense this advice now.

Tutorial 2 – Finding generated key at runtime

Enter any test data and observe the error message displayed.

Search for referenced text strings as mentioned in Tutorial-1. Scroll to the location shown below.

Notice the 2 ‘Key like’ strings in the text strings referenced. If you think that one of them is valid, then you are wrong, but then why and where is it used? And what is the correct key? We can find that out soon.
Double click the message ‘The serial you entered is not correct’ to reach the instruction location in the CPU window. When we analyze the code we come across a few concatenations operations. But unfortunately the keys are concatenated with blanks and finally compared with the user input.

The blank values you see in the comments are not really blank ones. They values are assigned on runtime. We have to set a breakpoint to obtain the dynamic assigned value.

To set a breakpoint, select the instruction and press ‘F2′. Breakpoints highlighted in red over the memory location.

Press the ‘Play’ button to run the crackme application. Enter any random data and click the ‘Check’ button. The application pauses at the breakpoint set in the previous step. Go to the same location where you saw the 2 suspicious ‘Key Like’ strings in the previous step.

Just before where the breakpoint was set we can find a new long string value displayed instead of blank strings which was displayed earlier. If you reverse engineer now, you can understand that the 2 Keys ‘L2C-5781‘ and ‘4562-ABEX‘ are static ones and are prefixed and suffixed, respectively, with a dynamically generated string. This is what we were looking for; the correct key to this app.

Conclusion : Never hardcode even fragments of static keys which can be helpful to deduce the complete key. Use some kind of logic to generate a dynamic key value.

OllyDbg is a 32-bit assembler level analyzing debugger for Microsoft Windows. This machine level debugger is created by Oleh Yuschuk for the 80×86. OllyDbg traces registers, recognizes procedures, loops, API calls, switches, tables, constants and strings. These features can be utilized to understand how an application internals.

Introduction

Ollydbg mainly has 4 windows in the default layout. CPU Window, Registers, Memory Stack and HEX Dump window. We will be working on CPU window most of the time.

A set of 3 tutorials illustrated here explains on how effectively can OllyDbg be used to identify the security holes and to ensure that the code written is healthy.
