In yesterday's New York Times, Sandeep Junnarkar described yet another malware trend: "Nick Groleau, a 40-year-old technical manager from Mountain View, Calif., received a message last month from a friend on his AOL Instant Messenger buddy list alerting him that Osama bin Laden had been captured. When he clicked on a link ostensibly directing him to a news article, it took him instead to a site offering a game to download. Although Mr. Groleau declined to download the game, his friend admitted that she had done so... Clicking on the link not only installed a game but also added a slick trick to propagate itself across the AOL Instant Messenger network, known as AIM.

Downloading the game also installed adware - software that runs undetected, tracking users' Web habits and interests, presenting pop-up advertisements and resetting the home page. 'This was not e-mail from some random person,' Mr. Groleau said. 'It came through AIM from someone I personally know. I clicked on the link right away.' It is that reflex that the perpetrators are counting on to transform IM services into a handy route to deliver spam (known as "spim" on IM), unleash viruses, create back doors into the systems of unsuspecting users and cause general mayhem across the Internet..."
