Philter Gateway

11/18/2003
Megaphat Industries was called by the Bachman
Group regarding a mail server experiencing
extremely high-traffic. It was estimated that
network traffic was increased by more than
700%. Over 300 spam messages were being sent
through the Bachman Group mail server. Although
mail relaying was restricted by the host,
the sender apparently found a way around this
restriction.
The Bachman Group was so overwhelmed by this
that they could not even utilize their own
network connection. With the use of the Megaphat
Philter Gateway and the proper configuration
of DNS BL Databases, 99% of the spam was stopped
before it even entered into the Bachman Group's
mail server. |
"Many
thanks to Megaphat Industries, NYC (www.megaphat.com)
for
their incredible work", was quoted by Steve Bachman,
President of the Bachman Group.
"They also tracked down the people in Taiwan
that were behind the attack. I am currently running
a program that they created called 'Philter'. This
program is, as I type this letter, handling over 300
attacks per minute from this outfit in Taiwan, they
don't give up easily. These attacks are being stopped
long before they can cause the system any more problems." |
| As
pleased as the Bachman Group may be with the results
of Philter, we are pleased that Philter can help
them not only prevent the abuse of their mail
server, abuse of their bandwidth and abuse of
their vital resources. We are also pleased to
see that they have found such significant results
with the Philter Gateway.
Coincidentally, the aforementioned client experienced
an extremely vicious attack only a week later.
An unknown IP address was sending over 150 connection
attempts per second causing a near Denial Of Service
to the Bachman Group network servers. In all 11
hours of the attack, approximately 800,000 connections
were blocked by these attempts with the help of
Megaphat's Philter Gateway. The Bachman Group
was very pleased by the results. |
