That, according to new research by Microsoft scientists who have developed a new method of distinguishing attacker-created spam email accounts from legitimate ones. The new finding, from researchers Yinglian Xie and Fang Yu of Microsoft is described as Social Graphs for Online Service Security. The two are using studies of legitimate and malicious social networks to spot bogus email accounts that are used to push spam, malware, and otherwise malicious links.
The researchers are analyzing natural social connections between users on the Web that are difficult for attackers or botnets to replicate. Spotting a spammer isn't hard, they say, when you look at his or her patterns of communication."
