Greetings,
Message boxes are coming up on my computer at seemingly random times. They
say something about a security vulnerability in Messenger Service and direct
me to
www.updatepatch.info.
At this website there is additional information about this supposed security
threat and then a link to download a patch.
I'm wary because the message box and the website come across as if the patch
is from Microsoft, but shouldn't the patch be available from the official
Microsoft website?
Any info much appreciated!
It's a scam, plain and simple. It's from a very unscrupulous
"business." They're trying to sell you patches that Microsoft provides
free-of-charge, and using a very intrusive means of advertising. It's
also demonstrating that your PC is very unsecure.
This type of spam has become quite common over the past couple of
years, and unintentionally serves as a valid security "alert." It
demonstrates that you haven't been taking sufficient precautions while
connected to the Internet. Your data probably hasn't been compromised
by these specific advertisements, but if you're open to this exploit,
you most definitely open to other threats, such as the Blaster,
Welchia, and Sasser Worms that still haunt the Internet. Install and
use a decent, properly configured firewall. (Merely disabling the
messenger service, as some people recommend, only hides the symptom,
and does little or nothing to truly secure your machine.) And
ignoring or just "putting up with" the security gap represented by
these messages is particularly foolish.

Whichever firewall you decide upon, be sure to ensure UDP ports 135,
137, and 138 and TCP ports 135, 139, and 445 are all blocked. You
may also disable Inbound NetBIOS over TCP/IP). You'll have
to follow the instructions from firewall's manufacturer for the
specific steps.

Oh, and be especially wary of people who advise you to do nothing
more than disable the messenger service. Disabling the messenger
service, by itself, is a "head in the sand" approach to computer
security. The real problem is not the messenger service pop-ups;
they're actually providing a useful, if annoying, service by acting as
a security alert. The true problem is the unsecured computer, and
you've been advised to merely turn off the warnings. How is this
helpful?
