Businesses and users are being warned that a new breed of malicious IM bots are duping users into spreading IM worm payloads.
Once the user is infected, the bot sends online users a message that appears to come from the infected user and attempts to persuade the user to download the worm payload. The bot was designed to send a follow-up message when the recipients of the message reply.
Just like many other worms, the IM bot utilize social engineering techniques create an interactive communication with intended targets, more effectively simulating a live user and increase infection rates.
By far, the worm has been identified on AOL Instant Messaging Network.
