Detection of Malicious Non-Executable Files Using Syntactic Structure

19.02.2013
A major portion of threats against end-user systems arises from non-executable files, e.g., PDF documents or Flash animations. Such files may contain malicious executable content which is launched when a file is opened in a vulnerable viewer. Such attacks are hard to detect due to the high complexity of respective file formats. Conventional antivirus products often miss malicious content hidden in the rich syntactic structure of file formats.

A research group at the University of Tübingen developed a patent-pending technology: a highly performant static analysis tool for detection of malicious PDF documents. Instead of performing analysis of JavaScript or any other content for detection, the new developed method provides a reliable means for detection of malicious files by focusing precisely on structural artifacts arising from embedded malicious content. The research group could demonstrate its effectiveness on a dataset of about 500,000 real-world malicious and benign PDF files: the new method outperforms each of the 43 antiviruses at VirusTotal and other specialized detection methods. Additionally, the new method is almost completely immune to nearly worst-case attack scenarios.

Im Focus: Glaciers melt faster than ever

Glacier decline in the first decade of the 21st century has reached a historical record, since the onset of direct observations. Glacier melt is a global phenomenon and will continue even without further climate change. This is shown in the latest study by the World Glacier Monitoring Service under the lead of the University of Zurich, Switzerland.

The World Glacier Monitoring Service, domiciled at the University of Zurich, has compiled worldwide data on glacier changes for more than 120 years. Together...

Im Focus: Quantum Matter Stuck in Unrest

Using ultracold atoms trapped in light crystals, scientists from the MPQ, LMU, and the Weizmann Institute observe a novel state of matter that never thermalizes.

What happens if one mixes cold and hot water? After some initial dynamics, one is left with lukewarm water—the system has thermalized to a new thermal...

Im Focus: On the crest of the wave: Electronics on a time scale shorter than a cycle of light

Physicists from Regensburg and Marburg, Germany have succeeded in taking a slow-motion movie of speeding electrons in a solid driven by a strong light wave. In the process, they have unraveled a novel quantum phenomenon, which will be reported in the forthcoming edition of Nature.

The advent of ever faster electronics featuring clock rates up to the multiple-gigahertz range has revolutionized our day-to-day life. Researchers and...
