SONICWALL INTERNET THREAT PREVENTION PROTECTS CUSTOMERS AGAINST WINDOWS EXPLOITS TARGETING 'WORLD OF WARCRAFT' PLAYERS

SUNNYVALE, CALIF. - April 12, 2007 - SonicWALL, Inc. (NASDAQ: SNWL), a leading provider of network security, email security, secure remote access, and backup and recovery solutions, confirmed today that users of its Unified Threat Management (UTM) technology are protected against malware targeted at World of Warcraft (WoW) players. WoW is a popular online computer game published by Blizzard Entertainment, with more than 8 million players worldwide.

SonicWALL first began providing protection against this malware in October, 2006, and has been issuing new signatures on a continual basis as more variants of the malware, designed to steal the in-game assets of WoW players, have been identified.

The Windows vulnerability is exploited by installing keylogging software on players' computers if they visit an infected web site. This allows hackers to obtain players' WoW passwords, access WoW player accounts and steal their virtual assets. While Blizzard Entertainment does not officially allow players to buy or sell assets, a thriving unofficial market for WoW assets exists.

"Although the malware currently only targets game players, it's important to protect against it in the workplace since keystroke loggers bring risks into a business network," said Alex Dubrovsky of SonicWALL's Security Center.

Users of SonicWALL's dynamic threat prevention services are protected by the signatures:
