Trent,

Yes we had a Win2K server that got hit and it has never had the
full version of MSSQL Server on it. MSDE was installed as part
of MailMax 5 (a mail server) install.

Hi all,

The problem is that if you say that good things come out of this there will
be people out there who get inspired to write new worms with the argument
that they "do good to the society" without considering the side-effects, or
who just use it as an excuse to do damage. Also it's human nature (or
something like that) to have the opinion that if something is bad you aren't
allowed to say that it has something good in it too, but that's not really
an objective argument.

In fact the worm might have done lots of good - some of the vulnerable
databases probably contain very sensitive information. A DoS of the Internet
doesn't last forever, but if sensitive information from databases get into
the hands of the wrong people it's a long-lasting problem. Sensitive
corporate information, and especially sensitive information about
individuals, and so on. I would rather have no Internet access for a few
days than have sensitive information about myself leaked to the wrong
people. Of course the perfect solution would be if those responsible for the
databases make sure they're secure, but in a world that isn't perfect a worm
might force them to make sure they're secure. Unfortunately lot's of people
think they can neglect security as long as they don't see anything bad
happening (and they often go selectively blind on purpose). I know for a
fact that a lot of people responsible for very sensitive systems neglect
security more or less on purpose for different reasons, and their only touch
with reality is when they're struck with a worm or similar. Hopefully some
of them have learned to take security more seriously now, and hopefully some
sensitive information that would have leaked out in the future won't do so
now, because of the worm. So I believe he wrote that - seriously, I do. ;-)
That aside, I *don't* think releasing worms is a good way to solve the
problem!

Jason,

I can't believe you wrote this - seriously, I can't.

What good can come of a widespread DoS of the Internet? What about the
problems that come hacker getting a hold of the payload and making it
more malicious before everyone can respond? Remember, most people won't
know about this until Monday and won't be able to fix the problem until
later that day, or perhaps later in the week.

It shouldn't have needed it. Microsoft released a patch for the
vulnerability some time ago (granted it wasn't easy to install,
especially for MSDE installations) but the real problem is those system
administrators who don't apply patches when there is no good reason not
to, and the network and firewall administrators who, for some
incomprehensible reason, leave open ports like this in their firewalls
and routers.

Maybe the time has come to draft legislation to prosecute not only the
writers of such malware, but those who recklessly leave their systems
vulnerable and defenseless and, through their negligence, help propagate
malware. Lastly, Microsoft and all other vendors need to make their
patches available for all configurations and easier to install (a quick
check shows that SQL Server SP3 is still not available for MSDE).

Consider that in order to exploit a target, it is counter-productive to
inspire fear within this target.

I do agree that this exploit was likely neither a Terrorist act nor primarily
designed to inpire fear. Far more likely it was designed to make headlines,
and a name for someone.

Unfortunatley the "anything" is the Internet, and "vulnerability" is
the CPU-bound nature of routers and the finite capacity of network links.

Apparently one of my dialup users is infected, so it's likely this
does affect the DE. In 5 hours one of my access servers blocked 6008
outbound udp packets to port 1434. They were blocked because the
source addresses were randomized.

Symantec has posted a new version (1.0.3) that correctly identifies an
unpatched MSDE installation.

Thanks to David @ Symantec for following up with me, the tool can be
downloaded at:

I just got a confirmation from Symantec. The fixSQLex.exe tool

(
http://securityresponse.symantec.com...sqlexp.worm.r=
emo
val.tool.html )=20

DOES NOT DETECT or fix MSDE, only SQL Server. They are working on an
update, it should be posted today.
