New Virtual Korset to Prevent Malware Attacks


Scientists from the Tel Aviv University developed a one-of-a-kind software program dubbed "Korset" that is able to stop malware from damaging servers that run on Linux, operating system used by most web and email servers around the world.

According to Avishai Wool, a professor in the university's Faculty of Engineering, the newly created program is able to predict the future behavior of any malware that resides inside a computer for years after developing immunity to various anti-virus solutions.

"We modified the kernel in the system's operating system so that it monitors and tracks the behavior of the programs installed on it. When we see a deviation, we know for sure there's something bad going on," says Prof. Wool, who worked on the project with his graduate student Ohad Ben-Cohen.

In terms of efficiency the new software program can be more useful than costly anti-virus protection. "Our methods are much more efficient and don't chew up the computer's resources," stated the professor.

But Prof Wool outlined that the new software program was developed to make Internet safer and not to provide competition for various anti-virus software manufacturers.

It is worth mentioning that usually anti-virus software developers grab viruses "in the wild" and pass them to isolated computer laboratories for research. Afterwards specialists identify the signature that the computer virus generates. The signature is then sent in form of an anti-virus update to users. The main problem is than the whole process takes too much time and hackers can attack a computer before the update is installed.

"There is an ongoing battle between computer security experts and the phenomenal growth of viruses and network worms flooding the Internet. The fundamental problem with viruses remains unsolved and is getting worse every day," says Prof. Wool.

According to the professor, users will have more chances of securing themselves from malware if they don't click on the links that claim to be from PayPal, banks or credit card companies.

"Most legitimate companies like banks never ask their clients to click on links in an email. Be suspicious if a company asks you to do this - access your account through bookmarks you've set up, or directly through the company's homepage," the professor says.

This summer the scientists performed a presentation on the model software at the Black Hat Internet security conference, which was held in Las Vegas.
