Kinda lame.. -----Original Message----- Sent: Thursday, July 30, 1998 7:36 AM Subject: FW: Network Abuse - Netblock de.le.te.d - IMPORTANT ---------- From: Andrew Shoemaker[SMTP:[email protected]] Sent: Thursday, July 30, 1998 6:43 AM Subject: Network Abuse - Netblock de.le.te.d - IMPORTANT Hello 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 regards, Andrew Shoemaker JNS Security [email protected] 617.442.5408 -- jamie rishaw (dal/efnet:gavroche) American Information Systems, Inc.
