New proactive approach unveiled to malware in networked computers and data

04.06.2014

Cybercrime comes in all forms these days. One recent headline told of the creepware or silent computer snooping that resulted in the arrest of some 90 people in 19 countries. Miss Teen USA was among the victims. Her computer had been turned into a camera and used to spy on her in her own bedroom.

On the commercial front, Target suffered the largest retail hack in U.S. history during the Christmas shopping season of 2013, and now the Fortune 500 company's outlook is bleak with steep drops in profits.

New research to be announced at the June 2014 ACM Symposium on Information, Computer and Communications Security http://asiaccs2014.nict.go.jp/ in Kyoto, Japan has unveiled the causal relations among computer network events. The work effectively isolates infected computer hosts and detects in advance stealthy malware also known as malicious software.

The work was conducted under the auspices of a 2010 National Science Foundation CAREER Award grant to develop software that differentiates human-user computer interaction from malware http://www.nsf.gov/awardsearch/showAward?AWD_ID=0953638&HistoricalAwards=false.

That $530,000 award was presented to Danfeng (Daphne) Yao, associate professor of computer science at Virginia Tech. She worked with Naren Ramakrishnan http://www.cs.vt.edu/user/ramakrishnan, the Thomas L. Phillips Professor of Engineering, and her graduate student Hao Zhang of Beijing, China, a doctoral candidate in computer science.

The Virginia Tech computer scientists used causal relations to determine whether or not network activities have justifiable and legitimate causes to occur.

"This type of semantic reasoning is new and very powerful," Yao said.

"The true significance of this security approach is its potential proactive defense capability. Conventional security systems scan for known attack patterns, which is reactive. Our anomaly detection based on enforcing benign properties in network traffic is a clear departure from that," Yao added.

They will present their paper "Detection of Stealthy Malware Activities with Traffic Causality and Scalable Triggering Relation Discovery" on June 4. It will be published in the symposium's proceedings.

Virginia Tech Intellectual Property has filed a patent on this technology, and it is actually a continuation-in-part patent, following one of Yao's earlier patents.

Previously, Yao garnered a 3-year, $450,000 grant from the Office of Naval Research (ONR) on cyber security to quantitatively detect anomalies in Department of Defense (DOD) computers, mobile devices, command and control servers, and embedded systems deployed on navy ships.

Yao's career research focus has been on this methodology development for novel, practical, and quantitative anomaly detection. Specifically, she is analyzing causal relations of events and producing instructions for detecting anomalies in computer programs, systems, and networks.

Im Focus: Worldwide Success of Tyrolean Wastewater Treatment Technology

A biological and energy-efficient process, developed and patented by the University of Innsbruck, converts nitrogen compounds in wastewater treatment facilities into harmless atmospheric nitrogen gas. This innovative technology is now being refined and marketed jointly with the United States’ DC Water and Sewer Authority (DC Water). The largest DEMON®-system in a wastewater treatment plant is currently being built in Washington, DC.

The DEMON®-system was developed and patented by the University of Innsbruck 11 years ago. Today this successful technology has been implemented in about 70...

Im Focus: Computational high-throughput screening finds hard magnets containing less rare earth elements

Permanent magnets are very important for technologies of the future like electromobility and renewable energy, and rare earth elements (REE) are necessary for their manufacture. The Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, Germany, has now succeeded in identifying promising approaches and materials for new permanent magnets through use of an in-house simulation process based on high-throughput screening (HTS). The team was able to improve magnetic properties this way and at the same time replaced REE with elements that are less expensive and readily available. The results were published in the online technical journal “Scientific Reports”.

The starting point for IWM researchers Wolfgang Körner, Georg Krugel, and Christian Elsässer was a neodymium-iron-nitrogen compound based on a type of...

Im Focus: Atomic precision: technologies for the next-but-one generation of microchips

In the Beyond EUV project, the Fraunhofer Institutes for Laser Technology ILT in Aachen and for Applied Optics and Precision Engineering IOF in Jena are developing key technologies for the manufacture of a new generation of microchips using EUV radiation at a wavelength of 6.7 nm. The resulting structures are barely thicker than single atoms, and they make it possible to produce extremely integrated circuits for such items as wearables or mind-controlled prosthetic limbs.

In 1965 Gordon Moore formulated the law that came to be named after him, which states that the complexity of integrated circuits doubles every one to two...
