What is a logical bomb?
A logical bomb is a part of a computer program designed to perform a malicious function when certain conditions are met. For example, an employee can write a program, including instructions that are deleted by important files if terminated. Logical bombs can be included in an otherwise harmless program or a naturally harmful program such as a virus.
Unlike viruses, logical bombs do not repeat or spread to other systems. Logical bombs can therefore be done to focus on a specific victim without being a threat to others. The fact that they are not checked is also easier to write logical bombs than other malicious software.
Some logical bombs are programmed so that they perform a function on a certain date rather than after a specific event. This type of logical bomb is often called a time bomb. Harmful programs such as viruses, worms and Trojan horses are sometimes programmed to attack the host computer on a certain date, allowgIt is to distribute undetected throughout the computer system before they become active.
Sometimes logical bombs are programmed to activate when something happens. For example, an employee can propose a logical bomb to remove files when the system has not been recorded. The logical bombs of this nature are among the most dangerous, because the conditions for their activation can be fulfilled unintentionally. For example, if the programmer was not released but died unexpectedly, there would be no way to prevent the bomb from activating.
The program that performs a certain function when predetermined conditions are met is usually considered a logical bomb only if the user is undesirable and unknown. The test software that stops operating after a pre -determined period of time does not usually apply to logical bombs, even if it works in the same way. Logicabombs often sabotage the host systemIn some way, they remove important files or functionality or allow unauthorized access to the user's system.
One famous incident, allegedly involving a logical bomb, was an incident of a 1982 pipeline. The United States Central Intelligence Agency (CIA) could use such a technique to sabotate the Soviet gas pipeline for natural gas. According to Thomas C National Security Council account, Reeda was enrolled in the software, which the Soviets had stolen by the Canadian company. The Soviets used stolen software to control the pipeline and the logical bomb reportedly resulted in a huge explosion. There were no victims. However, the Reed's account has been questioned and the explosion may be caused by another cause, such as defective construction.
