Commtouch(R) (Nasdaq:CTCH), the developer of ground
breaking Recurrent Pattern Detection (RPD)(TM) technology for real
time anti-spam and zero-hour virus protection, today announced spam
trends and statistics for the month of August. The announcement was
based on data from the Commtouch Spam Detection Center, which analyzed
over 1.5 billion spam messages in the month of August 2005.
"Our analysis shows that spammers used Katrina to attract and hold
recipients' interest. Typically, the subject of the email relates to
hurricane related news, while the body of the message has nothing to
do with the hurricane that devastated Louisiana," said Oren Drori,
director of product marketing at Commtouch.
During a monitoring experiment of less than 5 hours, the Commtouch
Spam Detection Center identified more than 250 examples of such spam
outbreaks, with subject lines such as:
-- "today's headlines: hurricane katrina slams into gulf coast;
dozens are dead"
-- "travelnewsletter - katrina affects cruise itineraries. stay
safe!"
-- "hurricane katrina update - nationwide storm survey"
-- "Instantly track Katrina's progress john"
In other examples, variations on "Katrina" and "Hurricane" are
used in multiple ways within the subjects of spam. The objective is to
circumvent naive spam filters (such as Bayesian filters, which tend to
white list messages by 'positive' keywords). Examples include:
-- "Claim your stock car racing gift Katrina"
-- "El 'Katrina' podria costarle a las aseguradoras mas de 20.000
millones"
-- "Enter now for a complimentary trip to Maui Katrina"
-- "Get an overnight $1500 cash advance for Katrina"
-- "Katrina win a $50,000 scholarship"
-- "Sexy hottie Katrina strips down"
Note: spelling and mistypes are from the original messages.
The Real Content: Drugs, Money and Sex
While some spam may have masqueraded as messages relating to
Katrina, the true content of August 2005 remained similar to that of
previous months. The list is headed once again by pharmaceuticals
(29.15%), financing schemes (20.95%) and sex enhancers (14.19%).
