ScanSafe Blocks More Malware in July 2008 Than in the Whole of 2007

Leading Provider of SaaS Web Security Reports That Malware in July
2008 Has Increased by 87 Per Cent Compared With June 2008
LONDON & SAN MATEO, Calif.--(Business Wire)--
In its Global Threat Report issued today ScanSafe, the pioneer and
leading provider of SaaS (Software-as-a-Service) Web Security reported
that the total number of Web-based malware blocks has increased by 87
per cent in July 2008 compared to the previous month. Specifically,
the first two weeks in July have shown an extraordinarily high volume
of malware blocks.

The increase in Web-based malware was driven by the ongoing
compromise of websites which represented 83 per cent of all malware
blocks for the month. The increase was largely the result of the
continued SQL injection attacks which were responsible for 75 per cent
of all malware blocks in July 2008. As a result, July has had an
overwhelming number of malware blocks - 34 per cent more blocks than
the whole of 2007.

"In June 2008 we reported a 278 per cent increase for the first
six months of the year. That alarming trend has continued with the
number of Web-based malware blocks exploding in the first two weeks of
July," said Mary Landesman, senior security researcher at ScanSafe.

July 2008 also bore witness to an increase in social engineering
email scams designed to install malware - including backdoor Trojans
and rogue scanners - on victim's computers. Worryingly, 95 per cent of
ScanSafe customers fell for the scams and attempted to clickthrough to
the malicious sites, which represented 1.3 per cent of all malware
blocks for the month. Fortunately all ScanSafe customers were and are
protected from such malicious content.

"Although this may not seem like a high percentage, it is
extremely significant given that these scams are now able to get past
spam filters which typically provide a high level of protection from
this type of socially engineered malware," Landesman comments. "It is
disconcerting that cyber criminals are becoming increasingly
sophisticated in creating these scams, so much so that more and more
people are falling for them."

The ScanSafe Global Threat Report is based on an analysis of more
than 10 billion Web requests the company scans each month on behalf of
business customers in over 60 countries across five continents. It
represents the world's largest security analysis of real-world
corporate Web traffic.
