Over 90 Percent of Emails That Reached Companies in Q3 Were Spam, According to PandaLabs


GLENDALE, Calif., Oct 27, 2008 /PRNewswire via COMTEX/ --
PandaLabs, Panda Security's
malware analysis and detection laboratory, today announced that less than six
percent of emails that reached companies in the third quarter of 2008 were
legitimate correspondence. Moreover, 1.43 percent of emails contained malware.
The data, extracted from a sample of more than 123 million emails and analyzed
by TrustLayer Mail
(http://www.pandasecurity.com/enterprise/solutions/trustlayer/), the anti-spam
managed service from Panda Security, found the most frequently detected
strains of malware during this quarter included Netsky.P, and the
SpamtaLoad.DO and SpamtaLoad.CZ Trojans.

% spam % infected
January 76.27 1.84
February 87.83 3.08
March 86.51 1.32
April 94.75 0.88
May 94.71 0.97
June 93.35 0.87
July 90.43 0.98
August 93.01 0.99
September 91.89 2.34

"The percentage of infected emails increased significantly in September,
to more than double the levels that we had witnessed in previous months. This
could be related to the financial crisis, as cyber-crooks step up attacks to
enhance their chances of success and avoid the effects of the economic
recession," explains Ryan Sherstobitoff, chief corporate evangelist for Panda
Security.
PandaLabs found an alarming 91.77 percent of emails delivered to business
inboxes were spam. This number peaked in August when more than 93 percent of
mail traffic analyzed by Panda Security was cataloged as spam.
Much of this illicit traffic was sent from computers infected with bots, a
type of malicious code that allows cyber-crooks to take remote control of
compromised systems. Once a computer has been infected, it becomes what is
colloquially known as a 'zombie'. These 'zombie' computers, under the control
of cybercriminals, are then networked together to form 'botnets' which are
used for a range of malicious activities that includes sending spam. In the
last three months alone, over 330,000 new zombies were activated each day.
Top spam topics of the quarter included sexual enhancers (23%),
pharmaceuticals (19%) and loans (12%).

Subject Percentage
Sexual enhancers 23%
Pharmaceuticals 19%
Loans 12%
Replicas 10%
Pornography 8%
Other 18%

New Spam Trends
The third quarter of 2008 saw the expansion of the use of .swf (Flash)
files to dodge anti-spam filters. This particular strategy involves including
links in junk mail with interesting news headlines or erotic photos that then
connect to an .swf file. The files themselves are generally hosted on
legitimate websites but are actually designed to redirect users to the web


page that cyber crooks want to advertise. The most common sites involved in
this scheme were fake online pharmacies.
Another popular scam that arose in the third quarter was the use of
vertical writing and hidden characters to trick content-based anti-spam
engines. The technique involves writing messages vertically instead of
horizontally to avoid being caught before it can appear in a user's inbox.
Also included in these emails is an additional message contained in white font
that can only be seen once the user selects the content of the mail.
