A logic bomb is a type of malicious software code or script that lies dormant within a system until certain conditions are met. Once activated, it executes an unauthorized and harmful action, such as deleting files or disrupting normal system functions.
A programmer embeds the logic bomb within legitimate software or scripts, often posing as a routine part of the system. The logic bomb remains inert until specific triggers, such as a certain date or time, are met. Once activated, the logic bomb performs its intended function which can range from corrupting or deleting data to causing widespread system outages.
One of the most notable examples of a logic bomb is the Stuxnet worm. It was discovered in 2010 and specifically designed to target industrial control systems, particularly those used in Iran's nuclear facilities. The logic bomb was embedded within the code of legitimate software used in these systems. Once activated, Stuxnet was able to sabotage the centrifuges used in uranium enrichment, causing physical damage and significantly disrupting Iran's nuclear program.
In 2018, an employee at a Miami-based tech company called Click2Gov was charged with sabotage after allegedly planting a logic bomb in the company's software. The logic bomb triggered on certain dates and caused a data breach, compromising the personal information of thousands of customers who used the software to pay utility bills.
In conclusion, a logic bomb is a dangerous type of malware that remains dormant within a system until specific conditions are met. Once activated, it executes unauthorized and harmful actions, such as deleting files or causing system disruptions. Preventive measures, such as implementing access controls, conducting regular system and code scans, and keeping software up to date, can help protect against logic bomb attacks. It is vital for organizations to be proactive in their approach to cybersecurity to mitigate the risk of logic bomb attacks and prevent potential damages.
