The volume of worm infections exploded in the first half of 2009, compared with the second half of 2008, according to Microsoft. In
volume seven of the Microsoft Security Intelligence Report (SIRv7), the Redmond company indicates that Conficker and Taterf have made worm infections second only to those caused by miscellaneous Trojans. According to the software giant, worms such as Conficker and Taterf are designed to exploit unsecured file shares, as well as infect removable storage devices, while spreading from one machine to another. Microsoft warned that, unlike home users, enterprise IT environments were more exposed to the threat presented by worms because of unsecured file shares and removable storage.
