Hugh Pickens writes "Science Daily Headlines reports that a new tool has been developed (funded by the National Science Foundation, US Army Research Office and US Office of Naval Research) to prevent 'drive-by downloads' whereby simply visiting a website, malware can be silently installed on a computer to steal a user's identity and other personal information, launch denial-of-service attacks, or participate in botnet activity. The software called Blade — short for Block All Drive-By Download Exploits — is browser-independent and designed to eliminate all drive-by malware installation threats by tracking how users interact with their browsers to distinguish downloads that received user authorization from those that do not. 'BLADE monitors and analyzes everything that is downloaded to a user's hard drive to cross-check whether the user authorized the computer to open, run or store the file on the hard drive. If the answer is no to these questions, BLADE stops the program from installing or running and removes it from the hard drive,' says Wenke Lee, a professor in the School of Computer Science in Georgia Tech's College of Computing. Blade's testbed automatically harvests malware URLs from multiple whitehat sources on a daily basis and has an interesting display of the infection rate of different browsers, the applications targeted by drive-by exploits, and the anti-virus detect and miss rates of drive-by binaries."
