IM is the new threat vector in messaging, says Postini report

Wednesday, 1 February 2006, 4:24 PM EST

Worm attacks over instant-messaging networks increased tenfold in 2005, while e-mail spam remained constant at about 75% to 80% of all messages sent, according to an annual report issued by messaging security service provider Postini on Monday.

Postini generated its 2005 report by analyzing the messages that come through its global data centers where it filters customers’ messages for spam, viruses, and other malware. These centers scan a billion messages a day on average, according to Andrew Lochart, Postini’s senior director of marketing.
