Logic bombs are one of the dangerous malware that can wreak havoc on computer systems. Is there any way to deal with it?
FREMONT, CA: A logic bomb is an unwanted malicious code that is inserted into a software or operating system by hackers. This code lies dormant and gets triggered post the occurrence of a specific event. These bombs are harmless and unapparent until and unless the code wakes up to unload its harmful and malicious instructions.
Fraudsters create logic bomb virus to perform all sorts of damage to the system they are running on and can depend on one or more triggers prior to their setting off. In time-based logic bombs, also known as time bombs, the actions of the code take place at a particular time and date.
The logic bomb cannot be considered worse or better than any other virus because of its nature of lying dormant for days, months, or longer without the knowledge of the user. Therefore, it becomes harder to detect who made it, the way to stop it, and the extent of its damage.
Like malware, logic bomb viruses are identified and removed by anti-virus programs.
Generally, fraudsters make use of logic bombs in accordance with worms, viruses, and Trojan horses for achieving maximum damage. The behavior of these kinds of malware, when employed as a logic bomb, is akin to these bombs. Afterward, it changes its tactics drastically once the condition of the material is met.
In order to count as a logic bomb, the attack must:
• Lie dormant for a particular period
• Possess a payload that is not in knowledge of the user
• Be triggered by a particular action
Prevention of Logic Bombs
Fortunately, there are some disaster recovery plans to combat these logic bomb attacks. However, it is vital to perform some things in order to prevent them from happening in the first place. Some of them are
1. Scanning all the files periodically is very necessary. Since logic bombs are hidden among code, it is vital to check the compressed files to ensure that nothing is hidden in them.
2. Besides, it is very crucial to keep updating the anti-virus software regularly. It becomes easy for the logic bombs to enter the systems in the form of whatever new strain of malware exists in case the anti-virus software doesn’t possess all the patches for the latest viruses.
3. Enterprises should avoid pirated software. This is one of the most well-known techniques for delivering malware.
4. The organizations are also advised to train their employees on identifying phishing emails. Email attachments are another very malicious and common malware delivery system.
5. Additionally, unsecured web links should never be trusted as it can lead to an infected site.
