Study: IM threats zooming up

The number of threats targeting instant messaging has soared, according to IMlogic, which tracked a 1,500 percent increase in the past year.

IMlogic's Threat Center said its data showed that huge increase in malicious code aimed at IM services between October 2004 and October 2005. Of these, 87 percent of unique IM-targeted attacks were worms, 12 percent were viruses and one percent was client vulnerabilities, according to the research.

Very few of the attacks have caused serious damage, according to IMlogic. However, an unlucky 13 companies on the Fortune 50 have been hit with an IM-related security incident in the past six months, said Francis De Souza, CEO of the company, which provides products to protect messaging systems against attacks. He cited one instance in which 10,000 desktops were taken out.

"Attacks you can do over IM are more powerful. You don't just send messages, you can take over somebody's PC," De Souza said.

"IM is built for the very rapid spread of information," he added. "Messages get where they're going very quickly, but this means threats can also spread very quickly."

De Souza acknowledged that instant messaging services have yet to see the level of outbreak or serious threat which will really put the issue in the spotlight. "But we've had a few shots across the bows," he said.

The most commonly targeted IM service over the past year was MSN Messenger, which was the focus of 62 percent of instances, according to IMLogic's data. Second was American Online's AOL Instant Messenger with 31 percent, and third was Yahoo Messenger with 7 percent. September 2005 saw a reversal of the top two, with AOL targeted 66 percent of the time, MSN 33 percent and Yahoo 1 percent.

The IMlogic statistics also indicated that all threats exploited some form of social engineering in order to launch. These included techniques such as tempting users with an enticement to click on a link or attachment, suggesting it is still within the power of users who employ common sense to protect themselves.

IMLogic report misleading on Yahoo

Yahoo IM has had no worms on its network, only phishing attacks. Can IMLogic word their reports more clearly, as misunderstandings can easily confuse. Yahoo IM has had phishing attacks, but has had no worms on its network. I have repeated this stance on many places on the inernet. Hopely this message will get back to the guys at IMLogic, to stop misleading the public, in respect of the hard work the folks at Yahoo Messenger/ Yahoo Security team to keep malicious activity off the network. Have a nice day. Yours, n3td3v.
