Login bomb is another way to hack someone's private information.
Login bomb is an insider attack to the computer system in these times. This device is a piece of code that is written by one of a company's programmer and secretly inserted into production operating system (OS).
As long as programmer feeds in its daily password, it does nothing.
But if programmer is suddenly fired and physically removed from the premises without any warning, the next day, the logic bomb doesn't get feed its daily password, therefore it goes off.
In most cases, logic bomb checked the payroll.
