CyberGuard Corporation (NASDAQ: CGFW), a global provider of security solutions, and Network Appliance, Inc. (NASDAQ: NTAP), a leader in reliable data management solutions, announced that their joint Internet Access and Security solution protects against the dangerous Exploit-Byte Verify attack as reported by VitalSecurity.org. The attack is the first known infection to actually cross web browsers.

Even when browsing the net with a seemingly safe browser like Mozilla Firefox, the attack compromises the Microsoft® Internet Explorer browser and Spyware is automatically installed. Customers using the NetApp® Internet Access and Security solution, which includes NetCache® appliances and CyberGuard's Webwasher Content Security Management suite, are protected from "Exploit-Byte Verify" infections through Webwasher's proactive filtering technology. CyberGuard and NetApp have successfully partnered to provide a comprehensive appliance-based solution for Internet gateway security since 2001.

"As a company focused on protecting enterprises against the most serious and critical vulnerabilities as their security needs grow, it is critical to work with companies like NetApp to pace the industry with the most comprehensive security solutions," stated Dr. Horst Joepen, CyberGuard's senior vice president of strategic alliances and general manager of the Webwasher subsidiary. "This new threat is only the latest in a series of attacks where the new proactive filtering technology included in our Webwasher suite provides protection and improves Internet security for enterprise customers."

"Our customers don't accept compromises in Internet security," said Dave Kresse, general manager of the content delivery business unit at Network Appliance. "That is why they rely on our NetCache appliances for proxy and policy control. Together with Webwasher's advanced content security functionality, we are focused on blocking new threats, including viruses and worms, at the gateway, giving them no chance to travel inside a company's network and potentially attack critical data."

The new attack is based on a vulnerability in the original Java? Virtual Machine by SUN Microsystems. Digitally signed javascript applets can be crafted in a way that they execute outside of the sandbox with access to all system resources. Certain types of malicious mobile code have appeared recently that take advantage of this vulnerability. Most of the time they function as trojans, downloading malicious spyware as well as compromising the Internet Explorer security settings and installing malicious Browser Helper Objects (BHOs). Because of the generic nature of the code taking advantage of the exploit and the frequency of updates, pattern based anti-virus engines have a difficult time recognizing and preventing infections. CyberGuard's Webwasher suite does not rely on fingerprints but detects code actually trying to take advantage of the exploit and blocking it already at the gateway.
