I wrote earlier today about a new worm currently circulating on the Internet, which Panda Security identifies as the MSNWorm.GU.
This worm uses MSN Messenger, and other chat applications, to spread. It infects systems silently, and without any visible symptoms.
Infection occurs when the victim clicks on a download link contained in a message received from a contact. Clicking on the link installs the worm on the target system, and the infection begins.
So, is there anything unusual about this worm; is it just a one off occurrence? Not at all – instant messaging, unfortunately, is a primary channel used by cyber-criminals to distribute malware. In fact, recent statistics indicate almost 50% of worms use instant messaging applications to spread.
Regrettably, from a security perspective these applications can present considerable security risks. Security risks increase substantially when these programs are used to share files, folders, or in some cases even entire drives.
As with any other application you use on the Internet, having the knowledge that allows you to use it safely, and being aware of current threats, will make for a more positive experience when using these wildly popular applications.
The following is a series of sensible tips for users to get the most out of these programs, securely and responsibly.
You need to be alert to the dangers in clicking on links or downloading files from sources that are not known to you. Even if the files or links apparently come from someone you know, you have to be positive that it really was this person who has sent the message.
Check with your contact to be sure the files or links are genuine. Remember, if you click on those links or run those attachments without confirmation, you run the risk of letting malware into your computer.
Use only secure passwords and be sure to change them regularly. The longer and more varied they are – using a variety of different characters and numbers – the more secure they will be.
Revealing confidential or personal information in these types of conversations can make you an easy target for Internet predators. For added protection when using a public computer, ensure that you disable any features that retain login information to prevent other users from gaining access to your instant messaging once you leave.
It’s virtually impossible to avoid publishing your email address on the Internet, however, do so only when absolutely necessary. Cyber criminals are always on the lookout for accounts to target.
Above all, if you are a parent, take exceptional care with the access that your children have to these programs. The risk here goes beyond malware, as sadly, they could come into contact with undesirable, or even dangerous individuals.
