Are there any procedures in place to track down this kind of network abuse. In particular, is it possible that it is a stealth attack? Before you answer, take note that this is going to appear in Bob Metcalfe's column next week. ---------- Forwarded message ---------- Date: Mon, 8 Jul 1996 15:30:43 -0600 (MDT) From: Kevin Rosenberg <[email protected]> Reply-To: [email protected] To: [email protected] Subject: Re: Ping flooding Resent-Date: Mon, 8 Jul 1996 15:30:53 -0600 (MDT) Resent-From: [email protected] > Some months later we had an incident of massive amounts of forged email > from a site called SUNSETDIRECT.COM. For several weeks they sent forged We are currently undergoing a ping flood attack, though our upstream provider has filtered icmp from the host so the flood is no longer affecting our T1 line. The system administrator of the site that appears to be flooding us doesn't believe his site is the source of the attack. He states that he can't see the icmp packets, though I don't know how he is sniffing his wire. My questions are these: Is it possible for someone to forged the source IP address of an icmp packet? If so, do they have to be in some routing proximity, or can they forge the source address while they are connected from anywhere in the world?
