Any comments?
The blogger claims 9500 new legitimate sites being infected daily with
malware engines.

The emerging trend of malware embedded sites
Malware embedded web sites are steadily gaining a priority in an
attacker's arsenal of infection and propagation vectors, and we've
been witnessing the trend for over an year and a half now. Malware
authors seem to have found an efficient way to hijack, inject and
exploit legitimate sites or Web 2.0 services in order to serve the
obfuscated payload which is no longer purely relying on social
engineering tactics, but is basically exploiting unpatched client side
vulnerabilities to infect the visitors. Also, malware authors seem to
have started thinking as true marketers, taking into consideration
that a visitor will go through a potentially malware embedded site
only once and wouldn't visit it given the lack of content -- blackhat
SEO garbage -- so that they've stopped relying on having a malicious
site exploit a single vulnerability only, and started hosting multi-
browser, multi-third-party malware embedded sites, thus achieving
malicious economies of scale.
Here's a great summary courtesy of Sophos showcasing the increasing
number of sites with malware embedded payload :
"The figures compiled by Sophos's global network of monitoring
stations show that infected web pages continue to pose a threat,
affecting official government websites as well as other legitimate
pages. On average this month, Sophos uncovered 9,500 new infected web
pages daily - an increase of more than 1000 every day when compared to
April. In total, 304,000 web pages hosting malicious code were
identified in May."
The stats are a great wake up call for those still believing that
malware comes in the form of executables and is mostly using email as
propagation and infection vector. Moreover, these stats show great
similaties with the ones released by ScanSafe an year ago whose
conclusion was that based on 5 billion web requests there was once
piece of malware hosted on 1 of every 600 social networking pages
