SUNNYVALE, Calif., May 7, 2007 - Fortinet® - a pioneer and leading provider of unified threat management (UTM) solutions - today announced the top 10 most reported high-risk threats for April 2007. The report, compiled from all FortiGate™ multi-threat security systems in production worldwide, is a service of the Fortinet Global Threat Research Team.

April 2007's top 10 threats, as determined by the degree of prevalence are:

The April top 10 highlights the following:

• While last month detections of HTML/Volksbanken!phish dropped down to 21st place, with BankFraud.E ranking at 25th place and BankFraud.OD at 32nd place, April witnessed the return of phish detections at the top. BankFraud.E and Phishbank.BGU generic detections are totaling more than 16 percent of global hits on FortiGate™ appliances worldwide. Overall, phishing detections have increased by 13.72% (from 3.72% to 17.44% of all detections) since last month.
• Although in 10th place last month, Adware/ Solutions180 is now ranked at No. 8. Fortinet tracking shows an absence of activity peaks, which are characteristic of the use of large botnets for spyware/adware planting.
• A Stration variant, W32/Stration.JQ@mm was seeded so heavily this month that it took over the third place in our top 10. A look at its activity evolution along the month shows that the majority of detection hits were gathered on a single day: April 19, 2007.
• The W32/ANI07.A!exploit (aka MS07-017) has been steadily exploited along the month, and overall represents 1 percent of April's global malware activity, which is a tremendously high score for a mainly web-based exploit.
