Single-victim spam attacks skyrocket

ComputerWorld.com warns that:
"The number of cyberattacks that consist of one e-mail targeting no more than a handful of people is up sharply from last year, according to MessageLabs Ltd. "

Seems odd to me that there could be any financial benefit in targetting a selected range of people. However, it appears that the targets are large corporations or government departments and the aim is to steal information -- preferrably about people.
