My name is Andrew Shoemaker and I am the head security consultant at JNS. We
recently were the target of a denial of service attack that saturated our
Internet connection. This attack, known as a 'smurf' attack, uses unknowing
relays to source the at
tack. By relaying the attack through your network the attack is made
anonymous and increases in strength. This type of attack causes degraded
performance on both the attacked and relay networks and is the result of an
improperly configured router at you
r site. I urge you to fix your routers. If you are unable to do so, or do
not know how I suggest you call a security consultant. JNS is willing to
fix your router permanently for a one time fee of $100 US. If you are
interested in this deal please co
ntact me and I will send you a copy of our security contract and an invoice.
Netblock de.le.te.d was found to produce 11 replys for each packet sent.
This means if the attacker is sending at T1 speeds the amount of your
bandwidth used in relaying
the attack is equivalent to 11 T1s
