The number of combined IM- and Web-based attacks increased by 300 percent in the first quarter, compared with the last quarter of 2004, Websense said.
According to another recent report,. At the same time, market research company IDC estimates that by 2008, about 450 million people will be using an IM product. Brian Burke, IDC's research manager of security products, said that hackers are already exploiting problems with today's IM systems: "Employees who are not familiar with these new threats can easily open a new, seemingly innocuous IM message that pops up on their screen. With that one click of the mouse, they can get infected."
