The Church of Trojan Graced Fortinet's Most-Reported Threats for March 2008

SUNNYVALE, CA, Mar 31 (MARKET WIRE) --
Fortinet(R) -- the pioneer and leading provider of unified threat management
(UTM) solutions -- today announced the top 10 most reported high-risk threats
for
March 2008. Sundays may be a day of rest and worship for many, but the
Pushdo.EV Trojan malware was not honoring the Sabbath this past month.
Fortinet threat researchers witnessed a spike in activity over four consecutive
Sundays -- from February-end to March-end -- propelling the Pushdo variant
to the top threat spot. Pushdo.EV grabbed an impressive 13.5 percent of all
malware activity for the month, which allowed the Trojan family as a whole to
claim credit for nearly one-third of the total number of threats observed.

With intelligence gathered from Fortinet's FortiGate(TM) multi-threat
security systems
in production worldwide, the FortiGuard(TM) Global Security Research Team
observed the following broad trends for the month:

-- Pushdo.EV rose to the top of the list by sending out animated cards
that enticed recipients with the promise of nude photos attached;
-- Parasitic file infector, Virut.A, wins the award for steepest climb up
the chart, landing in fourth place from its 29th position in the previous
edition of this report;
-- MyTob and MyDoom families continue consistent activity with four
variants in the Top Ten list.

"Activities in the last month showed the strength of the Pushdo
botnet,which is a clear indicator that the socially-engineered mass e-card
approach
continues to gain traction," said Derek Manky, security research engineer for
Fortinet. "Consumers should be reminded that legitimate e-cards are not
generally
sent as attachments, but rather as links to a hosting Web site. And as a
rule of thumb, we should all avoid opening attachments from unsolicited emails."

Following are the Top Ten individual threats, Top Five threat families and
Top Five threat prevalence for March. Pushdo's influence in all three
listswas clearly evident. Top 100 shifts indicate positional changes compared
toFebruary's Top 100 ranking, with "new" representing the malware's debut in
the Top 100.
