Logic bomb is a term used to describe a malicious computer program designed to execute when certain predetermined conditions are met. The spelling of the word "logic bomb" can be explained using IPA phonetic transcription as /ˈlɒdʒɪk bɒm/. The "o" in "logic" is pronounced as a short "o" sound while the "i" is pronounced with a short "i" sound. The "b" in "bomb" is pronounced with a voiced bilabial stop while the "o" is pronounced with a short "o" sound.
A logic bomb is a malicious piece of code, also referred to as a time bomb, that is deliberately embedded within a computer system or software program. It remains inactive until specific conditions or criteria are met, at which point it initiates a predefined destructive action. The purpose of a logic bomb is to cause damage or disruption to the targeted system or compromise the integrity of the data stored within it.
When triggered, a logic bomb can perform a range of malicious activities, such as deleting critical files, corrupting data, or rendering the infected system inoperable. The activation criteria could be based on specific dates, times, user actions, or even the presence or absence of certain files or data. As an intentionally concealed threat, logic bombs are typically deliberately inserted by individuals with an intent to cause harm, including disgruntled employees, hackers, or malicious insiders.
Logic bombs can have severe consequences, resulting in financial losses, service disruptions, or even the breach of sensitive information. Often, their purpose is to exact revenge, convey a message, or gain unauthorized access to a system. Due to their concealed nature, detection of logic bombs can be challenging, requiring comprehensive security measures such as robust monitoring systems, regular system audits, and adherence to secure coding practices. Furthermore, user education and stringent access controls can provide an additional layer of defense against logic bomb attacks.
The word "logic bomb" is a compound term that combines "logic" and "bomb".
1. Logic: The word "logic" originated from the Greek word "logikē", which comes from "logos", meaning "reason" or "word". It entered English in the late 14th century, referring to the science or study of reasoning.
2. Bomb: The term "bomb" has its origins in the Latin word "bombus", which means "a deep hollow sound" or "a booming noise". It initially referred to a noise-making device rather than an explosive one. In the late 17th century, it came to describe an explosive device.
When these two terms are combined, "logic bomb" refers to an explosive or destructive element rooted in the principles of logical reasoning.
