Onderwerp: New Paper: More than 600 million users surf at high risk

Hi List,

For the last 18 month we analyzed the daily USER-AGENT data collected by
Google's Web search and application servers around the world to study how users
patch and update their Web browsers.

We came out that approximately 637 million (or 45.2 percent) users currently
surf the Web on a daily basis with an out-of-date browser – i.e. not running a
current, fully patched Web browser version.

And this is only the tip of what we call the "Insecurity Iceberg", not counting
all the vulnerable browser plug-ins.

One of the new concepts we came up for combating the inadequacies of
Web browser
patching was that of applying the food industries "Best Before" date to theWeb
browser and its plug-ins.

A reply from Robert Hensing at Microsoft
(http://blogs.technet.com/robert_hens...1/vulnerable-w
eb-browser-study-full-of-fail.aspx) says that your study did not include
minor version information for Internet Explorer, probably because such
information is not reported in the user-agent string. But fully-patched
copies of IE5 and IE6 are not insecure in the same way as an unsupported
version; Microsoft is still supporting them.

So is it true that your study calls anyone running IE7 secure, and
anyone running IE5 or IE6 insecure, regardless of their patch levels?

From your paper:

>>It is noteworthy that it has taken 19 months since the initial general
availability of IE7 (public release October 2006) to reach 52.5%
proliferation amongst users that navigate the Internet with Microsoft's
Web browser. Meanwhile, 92.2% of Firefox users have migrated to FF2.

Could this be due to the fact that Mozilla stops supporting, and issuing
updates for old versions just a few months after the release of a new
one?

I would agree with both those reasons and add that FF updates are not
hampered by the disabling of the inbuilt (and often seriously mistrusted)
OS auto-update mechanisms.

I also _suspect_ that a lot of pirated copies of Windows probably have
system updates disabled.

Also, back when I was working in a big company, we had Windows2000
laptops that the admins seemed very conservative in patching (at
least, if the output of hfnetcheck could be believed).

I imagine it's the same in a lot of other companies, if only for lack
of time for integration-testing: there may be dozens of IE5.5-only
intranet-applications that don't work with IE7 (or even 6) and that
may even break after specific security patches have been applied.
Some of these applications may be "legacy stuff" where the maintainer
(probably an intern or a defunct company) is no longer around.



cheers,
Rainer

Or could it be due to the fact that IE7 is not supported by a bunch of
vendors and businesses are not comfortable upgrading?

Kind of like Vista???
