Logic Bomb
Malicious code triggered by specific conditions to execute unauthorized actions.
Understanding Logic Bombs
Unlike traditional malware that executes immediately upon infection, a logic bomb is designed to stay inactive until a specific event occurs. These triggers can be time-based, user-activity-based, or system-event-based, making logic bombs particularly dangerous and difficult to detect.
Types of Logic Bombs
Time-Based Logic Bombs
Activates at a specific date or time.
Commonly used in insider attacks, such as disgruntled employees setting malicious code to execute after termination.
Event-Based Logic Bombs
Triggers when a particular action is performed, such as opening a file, launching an application, or logging into a system.
Often embedded in software updates, macros, or malicious scripts.
Challenges and Considerations
Difficulty in Detection: Logic bombs remain hidden until triggered, making them hard to identify before execution.
Potential for Insider Threats: Employees or contractors with privileged access may introduce logic bombs.
Impact on Critical Systems: Logic bombs in essential systems can cause severe operational disruptions.
Understanding and mitigating logic bombs is crucial for maintaining cybersecurity resilience and preventing hidden threats from causing catastrophic damage to organizational assets.
