AOL Cans ICQ Worm
Within the past 24 hours, America Online moved to block a worm that has targeted versions of its ICQ Pro instant messaging software.
The worm, known as W32.Bizex, spreads itself by messaging every contact on an infected user’s contact list, then opens up an Internet Explorer browser window displaying a link to the Web site Jokeworld.biz. The rogue Web site hosts the worm’s payload, and users become infected if they click on the link.
In response to the worm, an AOL spokesperson told BetaNews, "ICQ has already implemented a fix, which blocks any further distribution of the worm through ICQ Pro versions. The block was implemented by ICQ and does not require ICQ users to download any additional software. For users that have been impacted, and are having trouble running ICQ Pro, please be assured ICQ is working hard on finding a solution so that you can get back to normal use of your ICQ as soon as possible."
Only users of ICQ Pro are affected, all other versions of ICQ are not at risk from the worm. Despite this fact, AOL recommends the use of updated anti-virus software. Most popular instant messaging programs include settings to enable virus protection.
As they continue to grow in popularity, instant messaging programs have become the newest breeding ground for worms and viruses. These attacks often infiltrate peer-to-peer by exploiting their vast social networks.
In a recent example, a trojan horse advertising program called BuddyLinks attempted to dupe users into installing adware on their system by using a false news report detailing the capture of al-Qaida leader Osama Bin Laden as bait.
Symantec Security Response reports few instances of the W32.Bizex worm in the wild.
