How does a logic bomb work inside a computer system?

A logic bomb is a form of malware consisting of hidden, unauthorized instructions embedded within a computer program. These instructions are designed to remain dormant within the system until a specific, pre-defined condition or event is met, at which point the malicious code is triggered to execute its task.12

Logic bombs are often introduced into a system using the Trojan horse technique, where the harmful code is concealed inside an otherwise legitimate or seemingly innocuous program. Once activated, the bomb can perform various destructive actions, such as deleting critical files or erasing entire databases.12

Because logic bombs are intentionally designed to sabotage systems and cause unauthorized damage, their creation and deployment constitute a serious violation of ethical standards and cybercrime laws. Using technology to inflict harm or destroy property is fundamentally wrong and undermines the security and integrity of digital infrastructure.2
