Cloudmark Fastest to Respond to World War III Virus

Began Protecting Global Service Provider Customers 20 Hours Before Other Anti-Virus Vendors

SAN FRANCISCO, CA -- (MARKET WIRE) -- April 12, 2007 -- Cloudmark, Inc., the global leader in carrier-grade messaging security, today announced that the company's advanced fingerprinting technologies, in combination with the Global Threat Network, identified the "World War III" virus immediately after the first variants began to appear. As a result, Cloudmark was able to quickly and automatically respond during the Easter holiday to begin protecting its customers, including six of the top ten Internet service providers (ISPs) in North America, more than 20 hours ahead of service providers using alternative anti-virus (AV) solutions.

The WWIII virus, which appears to be another variant of the Storm worm widely propagated in early 2007 when hackers created an email masquerading as a news report, entices users with fictitious subject lines about the start of World War III or the United States bombing Iran. The emails include malicious attachments that infect the victim's machine if clicked on. Cloudmark identified and stopped the virus just after 11:00 a.m. PT on April 8, 2007, more than three hours before some of the free anti-virus products detected it and a full 20 hours before other anti-virus vendors were able to respond to the attacks. In fact, it appears that many anti-virus companies have yet to come up with a generic signature capable of detecting new variants of the storm worm and several security vendors did not release signatures to fully block the WWIII virus until the morning of April 10.

"In an effort to increase the propagation of malware, hackers are finding ever more creative ways to combine social engineering with malicious code while also circumventing existing methods of detection," said Vipul Ved Prakash, Cloudmark's founder and chief scientist. "For service providers, every second that a threat continues to spread puts millions of subscribers at risk and has the potential to lead to service disruptions, performance deterioration and customer churn. Whether responding to the original storm worm or this WWIII variant, Cloudmark has shown time and again that because our technology does not rely on static rules, heuristics or pattern detection, we are able to respond much faster to emerging viruses and variants."

Cloudmark's solutions combine Intelligent Message Fingerprinting algorithms and first response data from the Global Threat Network to continuously block harmful messages and variants in real time and in any language, format or network. Unlike traditional solutions that rely on complex and processing-intensive rules or heuristics, as well as with pattern detection that actually requires witnessing a certain number of incidents spread before starting to block the threat, Cloudmark scans messages for all forms of abuse using an in-memory cache of verified fingerprints that is updated every 45 seconds. The result is immediate response that narrows the service provider's window of vulnerability and reduces security risks for its end users.
