A complex computer worm has infected corporate networks and has affected more than 10 million computers this week, experts say. Infecting computers in the U.S., Europe and Asia, the Downadup worm - which focuses on Microsoft Windows - scans company networks trying to guess passwords in order to access corporate networks, experts found. If the password is guessed, the worm can then infect a computer and the entire network of servers it is connected to.
As a result, experts are calling for all computer users to install a patch from Microsoft and to use long, difficult passwords that cannot be deciphered.
The National Cyber Security Alliance recommends computer users employ the following password strategies:
- Change your password NOW. Passwords should be changed approximately every 90 days. Take the time now to make your password more complex.
- Passwords should have at least eight characters and include upper case (capital letters) and lowercase letters, numerals and symbols.
- Avoid common words: It is reported that this worm uses a program that using a dictionary-type program to discover common passwords.
- Don't use personal information -- name, children's name, birthdates, etc. that someone might already know or easily obtain.
- Use different passwords for each online account you access (or at least a variety of passwords).
- If you must write down passwords, under no circumstances should you store them in a document on your computer. Keep them in a secure location away from your computer.
"This extremely explosive worm outbreak shows that we all need to constantly keep our defenses up," said Michael Kaiser, executive director of The National Cyber Security Alliance. "The best way computer users can protect themselves is to use the most-up-to-date operating systems, anti-virus, firewall and spyware software, in addition to employing secure behaviors such as using complex passwords."
