MySpace Attack a ‘Wake-Up Call' for Organizations, Proves Most Attacks Now Infect Users Through Web Sites

Web 2.0 marks a lifestyle and workplace change, while also creating larger risk of infection via the Web

CHICAGO, December 6, 2006 - Aladdin Knowledge Systems Ltd. (NASDAQ: ALDN) the leader in Software DRM, strong authentication and content security solutions, today announced that the recent attacks surrounding the popular MySpace Web site strengthens Aladdin's ongoing research findings that most Internet threats now come from surfing the Web, leaving email a distant second as a tool to infect individuals and organizations.

Even email-based threats now direct users to the Web through links, leaving the Web as its final step before infection. Phishing, spyware and other attacks use today's constant Web browsing as their platform for fast, easy infection that can spread rapidly among Web site visitors. The furthering evolution of Web 2.0 marks a lifestyle and workplace change, where technology has brought a shift in attitudes and expectations, while at the same time also creating a larger risk for organizations and consumers tasked with securing their data, identities and privacy.

"The attacks we've seen this week that have the potential to infect millions of MySpace users and others, stand as a clear, powerful wake-up call for organizations that must protect their Internet gateways from malware and other threats," said Shimon Gruper, vice president of technologies for the Aladdin eSafe Business Unit. "We have documented a massive shift from email-based to Web-based threats, making Web surfing the #1 danger for organizations and their employees. Traditional anti-virus providers and enterprises can use this latest wave of attacks targeting MySpace as an example of the Web's dynamic, evolving use. Security solutions addressing this shift and providing tight Web surfing security is the only answer to match protection with the Web's evolution. For years, Aladdin's eSafe has been a pioneering solution, providing adaptive content security against cutting edge Web-borne threats, and now addresses the dynamic online threats that come with the arrival of Web 2.0 and technologies such as AJAX."
