Hi-tech criminals are racking up more than 100 attacks a second on the world's
computers, a survey suggests.
While most of these attacks cause no trouble, the Symantec report suggests that
one attack every 4.5 seconds does affect a PC.
The wave of attacks was driven by a steep rise in malicious software in
circulation, said the annual report.
The number of malware (malicious software) samples that Symantec saw in 2009
was 71% higher than in 2008.
Crime family
This meant, said Symantec, that 51% of all the viruses, trojans and other
malicious programs it has ever seen were logged during 2009. In total, Symantec
identified almost 2.9 million items of malicious code during that 12 month
period.
The steep rise in malware was driven largely by the growing popularity of easy
to use toolkits that novice cyber criminals are using to turn out their own
malware, said Tony Osborne, a technology manager for the public sector at
Symantec.
Some of the kits were available for free, said Mr Osborne but others cost a lot
of money. One, called Zeus, was available for around $700 ( 458) and many had
become so successful that their creators now offer telephone support for those
who cannot get them to work.
STAYING SAFE ONLINE
During 2009, Symnatec say more than 90,000 variants of the Zeus kit and it was
responsible for the growth of one of the most prolific malware families during
the year.
Zeus relies on spam to lure people to websites where victims will be tricked
into installing malicious code or which sneaks on to a computer via a known
vulnerability.
Often, said the report, this can help criminals set up botnets - networks of
hijacked home PCs that can be used to send spam or plundered for lucrative
personal data. In 2009, Symantec saw almost seven million distinct PCs that
were members of botnets.
There was one very simple reason that novices bought and used the kits, said Mr
Osborne.
"It's all about money," he said.
Established gangs were also showing no signs of holding back in their attempts
to steal saleable information.
"Why would they?" he said. "It's easy money and it's very hard to catch
people."
"It's become a day job for a lot of people," he said.
There was evidence, suggests the report, that professional cyber criminals were
tuning their tactics to try and get better results. Many now scour social
network pages for details about employees inside companies and craft their spam
and other messages to capitalise on the details they can gather.
The continuing growth of hi-tech crime meant that many developing nations were
starting to suffer significant numbers of attacks. Brazil and India were
becoming hot spots of cyber crime, said Mr Osborne.
This was because, he said, the infrastructure in those nations was rapidly
improving as people move to broadband and use the web for more and more of
their daily lives.
"Those are the places where education and understanding about security are
taking a while to catch up," he said.
