Updates On Pending Virus Attacks!

Undoubtedly many of you saw the report on 60 Minutes this weekend or read about it online. In an effort to keep our clients informed we wanted to send out some updated information.

On April 1st the Conficker worm will simply start taking more steps to protect itself. After that date, machines infected with the “C” variant of the worm may not be able to get security updates or patches from Microsoft and from many other vendors. The creators of the worm will also start using a communications system that is more difficult for security researchers to interrupt.

The Conficker worm, sometimes called Downadup or Kido has managed to infect a large number of computers. Specifics are hard to come by, but some researchers estimate that millions of computers have been infected with this threat since January. Current users of Symantec’s Norton security products are protected. Any client currently under CHIPS Managed Services Program is protected. We are making sure your virus software are updated and you have the latest definitions.

Symantec has a detailed technical analysis of the threat here

What does the Conficker worm do?
We don’t know the purpose of the Conficker worm. Today the worm has created an infrastructure that the creators of the worm can use to remotely install software on infected machines. What will that software do? We don’t know. Most likely the worm will be used to create a botnet that will be rented out to criminals who want to send SPAM, steal IDs and direct users to online scams and phishing sites.

The Conficker worm mostly spreads across networks. If it finds a vulnerable computer, it turns off the automatic backup service, deletes previous restore points, disables many security services, blocks access to a number of security web sites and opens infected machines to receive additional programs from the malware’s creator. The worm then tries to spread itself to other computers on the same network.

How does the worm infect a computer?
The Downadup worm tries to take advantage of a problem with Windows (a vulnerability) called MS08-067 to quietly install itself. Users who automatically receive updates from Microsoft are already protected from this. The worm also tries to spread by copying itself into shared folders on networks and by infecting USB devices such as memory sticks.
Who is at risk?
Users whose computers are not configured to receive patches and updates from Microsoft and who are not running an up to date antivirus product are most at risk. Users who do not have a genuine version of Windows from Microsoft are most at risk since pirated system usually cannot get Microsoft updates and patches.
