A rabbit (also known as computer bacteria) in computing and cryptovirology is any computer program (usually malicious) which lacks a logic bomb. Rabbits tend to replicate themselves or perform actions at a rate which ultimately lowers the computer's available resources to the point that it runs slowly or becomes unresponsive. Rabbit programs may be intentional, or the result of an oversight during programming. Rabbit programs are named for their similarity to biological rabbits and bacteria, which have a high rate of reproduction and replication over a short period of time.
