In case you haven't heard, there are now several different viruses in the wild that are using the MS05-309 vulnerability to infect and propagate. Two of these viruses -- WORM_RBOT.CBQ and WORM_ZOTOB.D -- went in the wild today, and causes infected systems to reboot. This is similar to the Sasser and Blaster worms.

Some companies have not been successful in protecting their environment. CNN is reporting that "Among those [companies] hit were offices on Capitol Hill, which is in the midst of August recess, and media organizations, including CNN, ABC and The New York Times. The Caterpillar Co. in Peoria, Illinois, reportedly also had problems." I have unofficial information that the County of San Diego and Small Business Association in Los Angeles were also impacted.

So, what can you do? If you support your own systems for security updates, help us protect the computing environment and apply the MS05-039 update to your systems as soon as possible. I can not emphasize enough how critical this. The last thing that we want is a viral infection impacting our clients, clogging up our network, and preventing business from continuing. The simplest way to keep our enviroment safe from these viruses is to apply the MS05-039 patch.
