Description: "You try to look innocent, but what's behind the curtain? Whatever you hide or pretend will be detected - this is certain!" On 27th December 2006 I found a sample of the Rustock.B Rootkit at www.offensivecomputing.net, which was only sparsely analyzed at this time. I was keen to study its behaviour, as I’ve heard a lot of stories about this infamous Rootkit. Rustock included several techniques to obfuscate the driver which could be stumbling blocks for the researcher. Analyzing the binary was quite fun. Recalling the work I’ve done over the last few days, it is clear that Rustock is quite different from most other Rootkits I’ve seen in the past. It is not much because Rustock uses new techniques, but rather because it combines dozens of known tricks from other malware which makes it very effective.

Description: Among the techniques reviewed will be memory inspection, debugging, hooking, as well as PE file examination. Techniques that malware use to avoid being inspected will be discussed along with ways to work around them. The malware workshop environment will also be walked through and each tool demonstrated so that the workshop attendee would leave with a good grasp of how and when to use them.

Description: This article describe the process of setting up an environment with Virtual PC 2007 to capture malware on Windows. Although being quite old it is interesting to see an alternative to VMWare.



"One of the best ways to learn about something is to play with it and see what it does and how it behaves in a controlled environment. This also applies to learning about worms and viruses, but the problem with doing this is typically the computer you used to experiment with was trashed in the process and rebuilding a computer from scratch can be a huge hassle. Now if could simply drop the now infected computer in the garbage when you were done playing, and with no cost, then there would be very little preventing you from learning about malware, if you so wished."

Description: This report presents a reverse engineering of the obfuscated binary code image of the Conficker C peer-to-peer (P2P) service. It implements the functions necessary to bootstrap an infected host into the Conficker P2P network through scan-based peer discovery, and allows peers to share and spawn new binary logic directly into the currently running Conficker C process. Conficker's P2P logic and implementation are dissected and presented in source code form. The report documents its thread architecture, presents the P2P message structure and exchange protocol, and describes the major functional elements of this module.

Description: This paper outlines the relevant steps to build up a customizable automated malware analysis station by using only freely available components with the exception of the target OS (Windows XP) itself. Further a special focus lies in handling a huge amount of malware samples and the actual implementation at CERT.at. As primary goal the reader of this paper should be able to build up her own specific installation and configuration while being free in her decision which components to use.

The first part of this document will cover all the theoretical, strategic and methodological aspects. The second part is focusing on the practical aspects by diving into CERT.at's automated malware analysis station closing with an easy to follow step-by-step tutorial, how to build up CERT.at's implementation for your own use. So feel free to skip parts.

Description: The first variant "Peacomm.A" was detected in the mid of January 2007 and since then it has grown to one of the most successful botnets ever seen in the wild. It uses an adjusted Overnet protocol for spreading and communication. Its main intense is spamming and DDoS attacking. Also the fast-flux service
network which is being used by the criminals behind the attacks is really amazing and frightening at the same time. As its botnet activities are not the focus of this essay, I've included interesting other papers covering these topics.

Description: At the end of 2007 stealth MBR rootkit was discovered by MR Team members (thanks to Tammy & MJ) and it looks like this way of affecting NT systems could be more common in near future if MBR stays unprotected.

"Good points" of being MBR rootkit:
full control of machine boot process-code is executed before the OS starts
rootkit does not need a file - code could exists in some sectors of the disk and it cannot be deleted as a usual file
rootkit does not need any registry entry because it is loaded by MBR code
to hide itself, rootkit needs to control only a few sectors of the disk

How MBR rootkit works :
Installer
MBR loader
Kernel patcher
Kernel driver loader
Sectors hider/protector
Kernel driver
Detection
Rootkit removal

Description: This project is to convert mrxnet.sys into readable C++ source code very similar to the equivalent native code in mrxnet.sys sample .

Copyrights:
-----------
These Files (except mrxnet.sys) were created by Amr Thabet and coyrighted (c) by him

Files:
------
1.mrxnet.sys : The rootkit sample
2.mrxnet.idb : The IDA Pro database for Version 5.1
3.main.c  : The main source code of mrxnet.sys rootkit sample (created by reversing manually of mrxnet.sys with only IDA Pro)
4.FastIo.c  : The FastIoDispatch (you could ignore this part

The others are used for compiling the source code

Notes:
------
The source code is 95% similar to the real rootkit but that doesn't mean it should work exactly like mrxnet.sys as it still contain bugs and need to be fixed

Description: TLD3/TDSS malware analysis, a good paper from rootkit.com

BEWARE - password of the archive: tdl3_analysis

TDL or TDSS family is a famous trojan variant for its effectiveness and active technical development. It contains couple compoments: a kernel-mode rootkit and user-mode DLLs which performs the trojan operation such as downloaders, blocking Avs, etc,. Since the rootkit acts as an “injector” and protector for the usermode bot binaries, almost all technical evolutions of this threat family focus on rootkit technology so as to evade AV scanners. .
