Significant rise in malicious spam and phishing
Over one quarter of malicious emails contain eight-year-old malware.
Email security firm eleven has reported a significant rise in both
malicious emails and phishing emails in the first quarter
In its latest quarterly report, the company says that while
spam levels stayed more or less constant, the volume of
emails with malware attached to it increased by over 80%.
The volume of phishing emails increased by more than double that
With about one quarter of spam advertising (fake) pharmaceutical
products, pharma spam continues to be the most prevalent. The company also
noticed a significant rise in casino spam in recent months, which now
accounts for close to one fifth of all spam. The third most common
subject in spam messages was fake luxury goods.
Given its notorious reputation and the many variants that exist, it
will come as little surprise that Zeus (also known as 'Zbot') was
the malware family that was most likely to be attached to emails; two
Zeus campaigns alone accounted for more than one third of all malicious
spam. More surprising was the fact that more than one in four
malicious emails contained a variant of the 'MyDoom' worm: MyDoom was first seen in
January 2004 and should thus
be detected by any anti-virus product - even those that
have not been updated for a long time.
For a long time it had been believed that malicious spam was a thing of the past
and that spam filters and
anti-virus products together made email a less attractive
method for cybercriminals to spread malware. However, the volume of
malicious emails saw a sudden spike in
August 2011, and this trend has
continued, with spammers using various credible-sounding subjects to
trick the recipients into opening the attachments. On a much smaller
scale, the use of malware attachments in targeted attacks also continues to
be a problem.
