TMCNet:  Message Systems and Commtouch Join Forces to Fight Zombies

[July 29, 2008]

Message Systems and Commtouch Join Forces to Fight Zombies

(Marketwire Via Acquire Media NewsEdge) CHICAGO, IL, July 29 / MARKET WIRE/ --

HostingCon '08 Booth #810 -- Millions of agile
botnets dodged defenses and polluted the Internet with email threats,
according to the
Q2 2008 Email Threats Trends Report issued by messaging and web
security technology provider Commtouch? (NASDAQ: CTCH).

While spammers and malware writers experimented with a few new techniques
during the quarter, no innovation was needed for zombies to continue
pummeling email users and networks with unwanted messages and hazardous
code. According to the report, 10 million zombie IP addresses are active
each day, on average, and spam levels throughout the second quarter
averaged 77 percent of all email messages.

"Zombie networks or 'botnets' are flooding email with malicious threats,
and wasting organizations' bandwidth and storage," said Amir Lev,
Commtouch's chief technology officer and president.

To counter the unrelenting zombie and botnet attacks, software solutions
provider Message Systems has integrated the Commtouch email security
technology into its EoN carrier-class mail transfer agent (MTA). Combining
high performance edge protection, message processing and policy-based
protocol with Commtouch's Recurrent
Pattern Detection (TM) technology, EoN delivers sustained performance
while supporting full protection that consistently achieves global
filtering rates of over 95 percent.

EoN's ability to centrally manage and share data between MTAs allows
detection of zombie/ botnet activity earlier than other edge software
providers by sharing real-time intelligent analysis of abnormal sender
behavior across the network, thus preventing the spammer from rolling from
one MTA to another to prolong a spam attack. Additionally, changes to
policies or blocking can be made in real-time, by way of seamless MTA
propagation, with no associated restart. By eliminating the restarts
incurred by other edge and MTA software providers, EoN gives service
providers the highest possible availability in the industry, with customer
reports of uninterrupted 100% availability over a 12-month time period.

"The dual protection provided by EoN and Recurrent Pattern Detection from
Commtouch is a significant tool to combat spam sent by zombies," said
Catherine Foster, Director Product Management for Message Systems. "Zombies
or botnets produce distinctive patterns that can be automatically detected.
Detection coupled with intelligent reporting and throttling techniques can
be used to block or slow down messages from zombie-infected computers.
This is also very valuable technique to immobilize internal messaging
network attacks from compromised webmail accounts."
