Yesterday, Microsoft released a total of four software patches to fix various security flaws. One patch in particular was labeled “critical” by Microsoft; it fixes a hole that could potentially let hackers take over a user’s computer. Victims would be at risk if they visited a website and installed a program that then downloaded malicious code. This “critical” patch affects only Windows 2000 users.
A second released patch fixes security holes that affect Microsoft instant messaging programs. These patches were assigned the second highest rating by Microsoft, that of “important.” The security flaw here affects all PC users of MSN Messenger and Windows Live Messenger. With out the patches, users could open themselves up to vulnerability during instant messaging sessions. A hacker might send a message containing a link to a video. If the victim responds to that invitation and then clicks on that link, he or she would be brought to a website where the malicious code could be downloaded.
Instant messaging has become a prime target for hackers these days. Most people know that it isn’t a good idea to open a suspicious-looking e-mail or click on a link in an e-mail. This makes it harder for hackers to reach people and plant the malicious code. These same people, however, are still likely to click on a link sent as part of an instant message. There are very few PC security programs that protect your computer from hacking through instant messaging programs. Thus, using instant messaging as a vehicle for viruses.
Finally, the last two patches that were released are for security fixes that affect the business sector. The programs that require the patches have to do with software development and corporate computer systems.
If you are a Microsoft user, you can set up your computer to receive updates and patches automatically.
