Malware and Spam On the Rise In 2012
If it seems your email inbox is getting cluttered with
spam again, its not your imagination. A German technology security firm says
unwelcome or dangerous e-mails were on the rise again in the first half of
2012.
The company, called Eleven, said it documented a clear
jump in the second quarter in particular: the bottom line shows 54.8 percent
more spam, 52.4 percent more identified malware, and 90 percent more virus
outbreaks.
In contrast, phishing e-mails saw an increase
particularly in the first quarter, when their growth rate jumped by 169.6
percent. Measured against total e-mail volume spam had an average share of 70.8
percent in the first six months of 2012. On June 29, the heaviest spam day of
the year until now, its share jumped to 89.2 percent.
The second main trend of the first half of 2012 was the
rise in spam, phishing, and malware campaigns targeted to a specific country,
customers of a regional banking institution or the users of specific services.
What set this apart was a clearly limited recipient area, credible content,
high language quality, and Websites that are almost perfect copies of the
originals. In other words, more sophisticated perpetrators.
In the first six months of 2012, Eleven registered
phishing campaigns against customers of Amazon Germany and Deutsche Postbank,
as well as PayPal users. Malware campaigns disguised themselves as phony mobile
telephone bills, postal notification slips, and tax notifications.
Valentines Day and Mother's Day in the U.S. were
highpoints of spam activity. Most recently Euro 2012 and the run-up to the
Olympic games in London have been marked by phishing campaigns. The most
popular trick in both cases: phony ticket lotteries requesting bank account and
credit card data.
The spam and malware are back, Eleven says, because
spammers are recovering from the law enforcement efforts that shut many of them
down in 2011. After the Rustock botnet was shut down in March 2011, the volume
of spam coming from Western countries was reduced to a trickle.
For several months, they did not place on the top ten
spam senders list at all. But in the second quarter of 2012 in particular, the
volume of spam from these countries was clearly on the rise, Eleven says.
And in the first six months of this year, the U.S. was
back on the list in sixth place, reaching fith in June alongside Germany in
third and the United Kingdom in eighth.
India, meanwhile, remains the number one country for
generating email-delivered spam and malware.
