Logic Bombs

Logic Bombs

"Logic bombs" are pieces of program code which trigger at a predetermined moment, which may be when a particular date is reached, when a certain command is run, or any other system event.

Therefore, this type of virus may be activated at a specific moment on many machines at once (and is therefore sometimes called a time bomb), for example, on Valentine's Day, or on the anniversary of a major event: The Chernobyl logic bomb activated on April 26, 1999, the 13th anniversary of the nuclear disaster.

Logic bombs are normally used for launching denial of service attacks by overwhelming the network capacity of a website, online service, or business.
