The review period is coming and i decided to write an entry to inform about the Webviz project. Till now the first output of the project is a proof of concept work[1] (requires WebGL supported browser, tested on Firefox 5 and Firefox 4, on other browsers i don’t guarantee it works fine).

The figure displays the visualized data. The elevations corresponds to the geograpical malware numbers. The more malware detected the higher peeks are represented with changing color.

We are realizing that the Forensic Challenge 8 - “Malware Reverse Engineering” - is really difficult to solve because right now we received just 5 submissions. For this reason we decided to extend the submission deadline again to July 31th.

Those who already submitted a solution before June 30th are granted the possibility to submit again thus taking advantage of this one-month extra time. Moreover a few extra bonus points will be assigned to them.

Folks,
Forensic Challenge 8 “Malware Reverse Engineering” put up by Guido Landi and Angelo Dell’Aera from the Sysenter Chapter is in full swing. Submissions are due by June 30th, so if you want to participate, you have 4 days left. We award little prizes for the top three submissions! Hope to see your submission.

One of the very first Android malwares, Geinimi has been analyzed in the application sandbox DroidBox that is currently being developed. The project is part of GSoC 2011 in collaboration with Honeynet and as a master thesis. The Geinimi application uses DES encryption, and it’s possible to uncrypt statically the content, see picture below.

But it’s very easy to do that because the key is not well hidden, so an approach by using dynamic analysis will be more interesting with complex samples. This first real-world sample analysis was carried out to specifically test the crypto API logging.

Taking a look at the first submissions it seems like the Forensic Challenge 8 - “Malware Reverse Engineering” - is quite difficult to solve. For this reason we decided to extend the submission deadline to June 30th.

Have fun!

Today Apple unveiled the next generation of OS X, Lion and new iOS 5. Among the features, I’m concerned about two features: AriDrop and iCloud.

My worry for AriDrop comes from its automatic discover ability. While services like Bonjour also has automatic discover ability, they are passive. On the contrary, AriDrop is active, allows user to send (drop) a file to another user. Sounds pretty convenient. But this just reminds the old Bluetooth worms. Although saving a file requires user’s permission, the worm continually pings the victim for ‘dropping’ the file, and most users will then get annoyed and permit the saving. So without further restriction, I would say AirDrop opens a new door for worms. Cheers!

Visualization is a niche area especially at the security analysis. As mentioned in a well-known sentence; “A picture is worth a thousand words”. The importance and the power of the visualization in the security area stands out with the ability to define multi-dimensional data with a single shape. When addressing the creating a mesh tiled 3D view on an Earth map, i was reading about the geoweb application development. A geoweb application consists of some components.

This summer, I will be dealing with the malware analysis distribution from a visualization perspective at a timeline and geographic basis. To collect data related with malwares, I installed the Dionaea, which is a successor of Nepenthes. The documentation of the Dionaea is plain and easy to follow. I chosed Debian Squeeze to install the honeypot on it. Installing the base system from netinstall CD and following the documentation was enough till i got an error message during the compiling process of Dionaea. “common” from the irc channel of Nepenthess was helpful about the solution of the problem. The problem was defined at http://sourceforge.net/mailarchive/message.php?msg_id=27441025. It was because of the wrong Cython version usage with a makefile error.

I am pleased to announce the next forensic challenge: Forensic Challenge 8 - “Malware Reverse Engineering”.

The challenge has been created by Angelo Dell’Aera and Guido Landi from the Sysenter Honeynet Project Chapter.

Submission deadline is June 15th and we will be announcing winners around the third week of July. We have a few small prizes for the top three submissions.

Have fun!

Project Description:
Proposed Capture-HPC Description

Capture-HPC is a high-interaction client honeypot that is capable of seeking out and identifying client-side attacks. It identifies these attacks by driving a vulnerable client to open a file or interact with a potentially malicious server. As it processes the data, Capture-HPC monitors the system for unauthorized state changes that indicate a successful attack has occurred. It is regularly used in surveys of malicious websites that launch drive-by-download attacks.
