Denial of service UDP-based attack designed for a 28.8-56k connection.


DoS.Win32.Panther.m1, DoS.Win32.Panther.m2


Flooder: A program that overloads a connection by any mechanism, such as fast pinging, causing a DoS attack.

DoS: An exploit whose purpose is to deny somebody the use of the service: namely to crash or hang a program or the entire system. Examples of DoS attacks include flooding the victim with more traffic than can be handled; flooding a service (like IRC) with more events than it can handle bomb; crashing a TCP/IP stack by sending corrupt packets; crashing a service by interacting with it in an unexpected way; or hanging a system by causing it to go into an infinite loop. For example, the Ping of Death exploit crashed machines by sending illegally fragmented packets at a victim. A common word for DoS is ""nuke"", which was first popularized by the WinNuke program.

  • The "Clot Factor" is a measure of how much a pest "gums up" a machine by adding registry entries, files, and directories. As more objects are placed in a machine, manual removal becomes more difficult and more error-prone.
