A logic bomb is a piece of code that is inserted into a software program with the intention of causing damage or harm. The code is designed to execute a certain action or set of actions when a specific condition is met. It is often referred to as a virus, but this is not technically accurate.

A logic bomb is not technically a virus because it does not replicate or self-propagate. It is a piece of code that is inserted manually into a software program. However, it can have just as devastating an effect as a virus.

A logic bomb can be used to destroy data, cripple a computer system, or even steal information. It is a very dangerous tool and should be avoided at all costs.
