It's pretty easy to poke sticks at Microsoft's sorry record in the area
of online security -- but to be fair, that's not surprising when you realise
how large a target they are and how many evil little sods are burning the
midnight oil trying to exploit the smallest hole in Windows or IE.
However, I find it impossible to defend Microsoft in any way after the
events of this past weekend.
As documented by any number of stories on the wires (the MSNBC story
I've linked to in the news section below provides a good summary), it
seems that a cracker or group of crackers launched what must have been
the most undodgable MS-specific exploit to date.
Indeed, as a result of this exploit, the average web-surfer was completely
vulnerable to having their PC hijacked and loaded up with malware. All they
had to do was connect to the Net and surf to the wrong website. And here's
the kicker -- that "wrong website" need not be some obscure cracker's page
with the name "i0wnUd00d.asp" -- in fact it could have been the pages
of any number of highly respectable and otherwise trustworthy websites.
Normally it's pretty easy for Microsoft to roll out the defence that it's
only users of unpatched software who are vulnerable to any particular
attack -- but not in this case.
That's because the exploit relies on at least one unpatched vulnerability in
the company's Internet Explorer browser -- a vulnerability that has been
known about for some time but was seemingly ignored by the update team.

What the crackers did was to identify an unknown number of websites using
on unpatched versions of IIS and then exploit a known vulnerability to
add code which embedded some Javascript into each page those servers dished
up.
That Javascript contained code that subsiquently exploited the unpatched vulnerability in
IE to automatically load a trojan from a Russian cracker's website. That
trojan effectively gave the cracker access to the PC for the purposes of
keylogging, spam relaying or whatever.
By knocking out the cracker's website, the threat posed by this particular
villain has been defused but as we all know, there are probably dozens of
other crackers out their right now already doing the same thing.
So why haven't Microsoft patched this IE vulnerability and what are they
doing about it?
Well it seems that their sole response has been to refer users to
this page.
I'm sorry, but this is kind of like Mitsubishi advising that the brakes could
completely fail without warning on their fastest sports sedans and then suggesting
that the fix is for people not to drive too fast in the meantime.
And, as we all know, this won't be the last such vulnerability to appear in
IE which, when compared to other offerings such as Opera and Mozilla/Firefox
is rapidly showing its age.
I strongly suggest (again) therefore, that people wake up to the fact that
using IE is the cyber-equivalent of taping a "kick me" sign to the backsides.
If the feature benefits alone aren't enough to convince you to switch then
stop and remember that right now you, your mother, your girlfriend and
all your loved ones who might be using IE may be just a mouse-click away
from the next implementation of this exploit.
Do yourself and them a favour -- get off the IE bandwagon now!
When the LTSA discovered that some Mitsi's might suffer a total brake failure
they ordered them off the road -- is it time to order IE off the web?
