WALTHAM, Mass. -- Over 30 New IM Viruses and Worms Reported to Threat Center in Q1 2005; Bropia and Kelvir Top List of IM Attacks on Corporate Environments

The IMlogic Threat Center, the industry's first global consortium to provide threat detection and protection for instant messaging (IM) and peer-to-peer (P2P) applications, today issued a threat warning for users of popular public IM networks in response to the increasing prevalence of IM viruses and worms. In 2005, the IMlogic Threat Center has reported a 50 percent monthly increase in reported IM incidents and more than 30 new IM threats including viruses, worms, and spam over IM (SPIM)/malware. Within the past 30 days, IMlogic has issued over 12 priority alerts to IMlogic Threat Center subscribers and IMlogic customers, responding to the increasing frequency and pervasiveness of IM threats.

Key data points released by the IMlogic Threat Center since January 1, 2005 include:

--More than 30 widespread reported incidents of new IM/P2P viruses, worms, and malicious code including SPIM/malware;

--81 percent of reported incidents include IM virus or worm propagation, with approximately 10 percent hijacking IM file transfer capability;

--13 percent of reported incidents utilized known client vulnerabilities or exploits;

--70 percent of reported incidents over IM networks targeted the MSN Messenger Client, Windows Messenger Client, and MSN Network;

"IM viruses and worms are growing exponentially and the IMlogic Threat Center is rapidly responding to provide first-line defense for these new classes of emerging threats," said IMlogic CTO and Vice President of Products, Jon Sakoda. "Virus writers are now shifting the focus of their attack to instant messaging, which is seen as a largely unprotected channel into the enterprise."

The IMlogic Threat Center is the first operation to provide detection, analysis, alert, and protection for harmful IM and P2P threats including IM-borne viruses, worms, SPIM, and malicious code. Launched with the support of Internet security leaders Symantec, Sybari, and McAfee, and global instant messaging leaders America Online, Microsoft and Yahoo!, the IMlogic Threat Center is the comprehensive knowledge base for known IM and P2P vulnerabilities and provides rapid response and guidance for protection against newly detected threats.

The IMlogic Threat Center has made available two new resources to help end users and corporate IT managers understand the risk associated with IM:

--IMlogic and charter IMlogic Threat Center partner Sybari Software have authored a white paper detailing the Top 5 Instant Messaging Security Threats for 2005. This white paper is available for free download at http://www.imlogic.com/resources/literature.asp.

--IMlogic IM Detector Pro, IMlogic's free IM detection tool, can be used to immediately detect and block IM traffic and stop potential virus and worm infection. Companies can download IMlogic IM Detector Pro at www.imlogic.com/imdetectorpro.
