Anti-Sasser Worm Message

[Chuck Grimsby]

As many of you know, I occasionally get messages from the MS team on
various things. Today I got the following, and (personally) I think
it certainly is worthy of passing on.

If you haven't protected yourself from the sasser worm, GET THE HECK
OFF THE NET!! <Grin>

No, seriously, get the patch. And a firewall. Even one of the free
personal ones like Zome Alarm or Outpost or whatever, and then
hopefully, someday, all this ... stuff... will stop. (Hey, I can
dream, can't I? Yeah, I know, there's always going to be someone who
says "it won't happen to me" and won't do anything. Then it happens
to them. And they spread it on to everyone else who said "It can't
happen to me!" <sigh> )

Ok, time for me to shut up and you to read the important part of this
message. So, Read the below and... "Let's be safe out there!"

What is this alert?

- Microsoft has been made aware of a worm identified as
"W32.Sasser.wor m" and it is currently circulating on the Internet.
The worm exploits the Local Security Authority Subsystem Service
(LSASS) vulnerability fixed in Microsoft Security Update MS04-011 on
April 13, 2004.

- Microsoft encourages customers to protect themselves against this
worm by installing Microsoft Security Bulletin MS04-011
<www.microsoft. com/technet/security/bulletin/ms04-011.mspx>
immediately.

- Customers who have enabled the Windows XP Firewall are protected
from the vector this worm attacks, which is TCP Port 139. Most third
party firewalls also block this attack vector by default.

If you have any questions regarding the security updates or its
implementation after reading the above listed bulletin you should
contact Product Support Services in the United States at
1-866-PCSafety (1-866-727-2338). International customers should
contact their local subsidiary.

I am continually astonished at the stupidity of the broadband ISPs
who sell users a package that puts their Windows PCs right there on
the Internet with nothing in between them and the wild and woolly
world out there.

If your computer has a broadband connection and your PC is connected
directly to the cable/DSL modem, YOU ARE AN IDIOT.

Buy a Linksys router and plop it in between. This by default uses
NAT so that nothing on the inside of the router is accessible from
outside connections. This means that any exploit that spreads by
initiating a connection from the Internet to your PC cannot infect
your PC.

If you don't want to spend the $50 on that, then install a software
firewall.

I am running my PC connected directly to RoadRunner's network
because of a problem with RR's network (I'm hoping that a change to
RR's network in the next month will restore my ability to run behind
my router). Indeed, I was running in that configuration last August
when Blaster hit.

Did I get infected?

No!

Why?

Because I had a software firewall (Tiny Personal Firewall) that
prevented blaster from connecting. I also had the RPC locator
service disabled so that it wouldn't have worked even if I had not
had a firewall.

I was in California at the time, so it was not a situation where I
could have changed configurations easily (I had VNC set up and
listening for connections, so I was able to connect to my PC and
remote control it to do various things like check my email).

So, I was running in a dangerous configuration, but I was still not
infected.

It used to be that I didn't recommend a software firewall for
dialup, because dialup users didn't get hit by connection requests
(this was based on my own experience of using a software firewall
with a dialup connection; I'd see a probe about once a week), but
that as changed drastically. You probably need a software firewall
with dialup, as well.
No, seriously, get the patch. And a firewall. Even one of the
free personal ones like Zome Alarm or Outpost or whatever, and
then hopefully, someday, all this ... stuff... will stop. (Hey, I
can dream, can't I? Yeah, I know, there's always going to be
someone who says "it won't happen to me" and won't do anything.
Then it happens to them. And they spread it on to everyone else
who said "It can't happen to me!" <sigh> )

This is a case where you should do several things:

1. get the patch.

2. get a firewall.

3. revise your network infrastructure to protect yourself by default
from outside exploits.

In regards to the patches, I don't usually install MS's security
patches because they mostly don't apply to me. But any RPC patches I
download and apply immediately, as those are pretty important. Same
with the LSASS patch (wasn't that what this worm was exploiting?).

But, again, if your PC is unreachable on a NAT subnetwork, it can't
be infected from an outside connection (initiated by a PC outside
your NAT subnetwork -- if there's another PC on your network that's
infected, it can infect all the NAT PCs) even if your PC has none of
the patches and no firewall running.

But don't get too complacent if you have that scenario -- it can't
protect you from worms that get to your PC through other vectors,
like email viruses. A NAT router won't do anything to stop an
outgoing connection from a trojan- or worm-infected PC.

Code Red and Nimda should have been the wake-up calls for everyone
when this came up, just as ILOVEYOU should have been for vbScript
and the Windows Scripting Host.

But most people simply don't pay attention.

And look at the mess we're in.

I've had nothing but dialup.

My Norton firewall reports a steady stream of SQL Server Worm attempts.

But that wasn't the case before Code Red and Nimda. I know, because
I had dialup then.

You certainly need it now.

That's the first hit but that's an online forum. A posting by Bernard Cheah whose
real name is likely Chun Hai Cheah who is an MVP.

Another word of warning, although Windows XP has a built in firewall, it
is not activated during setup so unplug your BB connection when setting
up Windows. I got the Welchia worm this way, didn't really stand a
chance since the worm was there during setup, the first program I
installed was NAV, which detected it.

WinXP service pack 2 will roll out a new firewall and will turn it
on by default.

But it doesn't fix the installation, which won't have the SP applied
until after installation.
