Some might wonder why exploited vulnerabilities are listed in the malware section, but then also have a section of their own. Well, malware often relies upon exploited vulnerabilities to be installed properly. At the same time, user behavior can do it as well through social engineering techniques. Vulnerability exploit is at the heart of hacking and data breaches. Worms, viruses, malware, and a host of other attack types often rely on vulnerability exploit to infect, spread, and perform the actions cyber criminals want. According to a Microsoft Security Intelligence Report, Conficker was the top threat to enterprise computers during the first half of 2009. Worm infections have doubled between the second half of 2008 and the first half of 2009.
We got such a great response to a guest contribution by Perimeter CTO Kevin Prince over at our Network Security Edge site about his views on the top threats for this year that we asked him if we could use the information as the basis of this quick presentation.
You'll get a lot of useful info by clicking through these slides, but we strongly encourage you to check out Prince's full analysis of 2009's trends and his thoughts on the threats, both growing and persistent, facing your network.
