As reported last week, hackers are scheming about how to exploit the latest announced vulnerability in a number of Microsoft operating systems and applications, including Microsoft Office and several versions of Internet Explorer.
The newly reported weakness allows malignant JPEG images to enter users' computers undetected via e-mail, Web site and instant message downloads, enabling an attacker to gain control of the computer. CyberGuard prevents attacks that might leverage the imaging vulnerability with its Webwasher Content Security Management (CSM) solution.
Webwasher's CSM solution has built-in provisions that defend against new threats from file types that have previously been considered "harmless." On Friday, September 17, CyberGuard's Webwasher activated deep file inspection for JPEG files. Within minutes, Webwasher customers around the world were protected via their next automatic security update of any Webwasher product.
"Technology is in a constant state of evolution. We could spend all day updating patches and scanning for new threats just to keep up," explains Mike Wittig, CyberGuard's president and chief technology officer. "Instead, Webwasher relies on a deeper examination of files to prevent malicious viruses, worms and Trojans from infiltrating networks. Our customers know they can rely on CyberGuard's technology to protect their brand and their information assets."
In addition to prescanning content for infected images, Webwasher version 5.0 and higher protect against malicious files by reconfiguring the generic body filter available in most Webwasher products, not only its antivirus product.
