First, in a SYN packet from the client, to which the service responds with a SYNACK. In the TCP/IP protocol, a three-way handshake takes place as a connection to a service is established. However, it is still included here for historical reasons, as the Ping of Death helped get the whole DoS craze really going, since it was so easy to perform. Most systems have patches available to prevent the Ping of Death from working.

There are also source code examples available for Unix platforms that allow large ping packets to be constructed. By simply typing in "ping -165527 -s 1 target" you can send such a ping. Windows NT is capable of sending such a packet. This causes unpredictable results, such as reboots or system hangs. However, due to the size of the packet once it is reassembled, it is too big for the buffer and overflows it. The target receives the ping in fragments and starts reassembling the packet. The Ping of Death is a large ICMP packet.

Reasons that a hacker might want to resort to DoS might include the following:

Regardless of your feelings, DoS has been steadily gaining in popularity, whether with hackers mad at other hackers, sysadmins mad at spammers, or whatever - virtually everyone we've run into that is aware of the potential of DoS at least has software to do it, admins included. Ask yourself which is more alarming - the number of kids trying DoS attacks, or the number of DoS attacks that succeed?
We prefer to think of them as just one more kind of tool in the toolbox, and as such, will continue to include material on them in the Hack FAQ. This is a controversial subject, since some people think that DoS is not a hack, and/or is rather juvenile and petty. This section covers basic info regarding Denial of Service attacks.ĭoS (Denial of Service) is simply rendering a service incapable of responding to requests in a timely manner.
