DNS Hijacker

DNS Hijacker is a libnet/libpcap based DNS sniffer/spoofer. A versatile tool, it supports tcpdump-style filters that allow you to specifically target victims. DNS answers are forged based on entries in a "fabrication table" or by simply forging one answer to all requests. A print-only mode is also supported, allowing one to simply monitor DNS traffic. DNS Hijacker is an excellent tool for blocking and removing advertisements at the network level. The package comes with a default rule file for blocking about 780 known ad servers, as well as instructions on how to incorporate with RRDTool for ad blocking statistics generation.

          Perhaps you should rethink your statement. This tool is only effective on a LAN and requires a lot more work then simply running it in order to actually attack anyone. Furthermore aside from the comical effect of such a tool don't forget the practical use of running DNS Hijacker on your LAN to put a quick end to ad servers, or perhaps even as a low budget "net nanny".
