Instant messaging attacks are on the rise. Akonix Systems Inc., a messaging security developer, said in their Q3 Threat Report that 25 viruses have been reported on IM networks so far in September, or about one a day. In the past, malware was repurposed from email viruses, but now IM-targeted viruses are just as likely. Hackers are using IM to take over PCs and carry out zombie-style attacks via the major consumer IM networks AOL, Yahoo, and MSN. Corporations using IM need to get off the consumer networks to avoid this threat.
