What triggers a logic bomb?
A logic bomb is a malicious program that is triggered when a logical condition is met, such as after a number of transactions have been processed, or on a specific date (also called a time bomb). Malware such as worms often contain logic bombs, behaving in one manner, then changing tactics on a specific date and time.
What is logic bomb explain with example?
A logic bomb is a piece of code intentionally inserted into a software system that will set off a malicious function when specified conditions are met. For example, a programmer may hide a piece of code that starts deleting files (such as a salary database trigger), should they ever be terminated from the company.
How is logic bomb protected?
Use a Reputable Antivirus Program and Keep It Updated A robust antivirus program can protect your devices from viruses and malicious codes that might be carrying logic bombs. To help protect your PC from any potential threats, you should keep the antivirus program up-to-date.
What is a logic bomb and how does it work?
A Logic Bomb is a piece of often-malicious code that is intentionally inserted into software. It is activated upon the host network only when certain conditions are met. Logic bombs execute their functions, or launch their payload, once a certain condition is met such as upon the termination of an employee.
How do logic bombs and worms work?
How do logic bombs and worms work? Logic bombs execute when a certain set of conditions is met and are spread when infected files are passed from user to user, whereas worms run independently of host file execution and are much more active in spreading themselves.
How are logic bombs used in malicious software?
Software that is inherently malicious, such as viruses and worms, often contain logic bombs that execute a certain payload at a pre-defined time or when some other condition is met. This technique can be used by a virus or worm to gain momentum and spread before being noticed.
What’s the difference between time bombs and logic bombs?
Trojans and other computer viruses that activate on certain dates are often called ” time bombs “. To be considered a logic bomb, the payload should be unwanted and unknown to the user of the software. As an example, trial programs with code that disables certain functionality after a set time are not normally regarded as logic bombs.
Is there a logic bomb that can wipe Linux?
Symantec reported that the malware also contained a component that was capable of wiping Linux machines. On 19 July 2019, David Tinley, a contract employee, pleaded guilty for programming logic bombs within the software he created for Siemens Corporation.
Who is responsible for the logic bomb virus?
Typically, most logic bomb malware specimens are planted and secreted by a malicious insider, particularly those users that have administrative access to systems. For example, in early 2008, a system administrator was sentenced to 30 months in prison for embedding malicious code designed to wipe out critical data stored on more than 70 servers.52
