SUNNYVALE, Calif., August 11, 2005 - Fortinet - the pioneer and market leader of Unified Threat Management and only provider of ASIC-accelerated, network-based multi-threat security systems for real-time network protection - today announced that its FortiGate™ integrated security appliances, FortiMail Secure Messaging Systems and FortiClient™ Host Security software protect against W32/Dumador.DH-tr, a new backdoor Trojan for the Windows platform that uses spyware and keylogging to collect and submit sensitive personal information via the HTTP protocol.

As a backdoor Trojan, W32/Dumador.DH-tr does not spread by itself; instead, users get unknowingly infected when visiting malicious Websites. W32/Dumador.DH-tr collects personal information such as Social Security, credit card and bank account numbers, eBay and PayPal account numbers, online user names, passwords, and more, and sends this information to a remote server. It can also install itself into the Windows egistry, record keystrokes and reduce overall system security by changing browser settings, preventing access to antivirus websites and opening a backdoor port in the infected computer. This latest backdoor Trojan is currently affecting users worldwide and Fortinet rates W32/Dumador.DH-tr as a high-profile "Level Two" threat.
