Monthly Malware Statistics, September 2010

Kaspersky Lab presents its malware rankings for September.
There are relatively few new malicious programs in either ranking. It is, however, worth highlighting a new ‘bundle’: Trojan-Dropper.Win32.Sality.cx which installs Virus.Win32.Sality.bh to an infected computer. The dropper spreads using a vulnerability in WinLNK files (i.e., Windows shortcuts). It's also worth noting that in September the number of exploits targeting CVE-2010-1885 (the Windows Help and Support Center vulnerability) was significantly lower than in August. Another September trait is that the number of exploits – 7 - in the Top 20 was equal to that of adware programs.
