Question

A hidden computer programmer that is set to disturb a computer system or network, which is triggered on a present time or some other pre-defined state of the system is called:

• A. Logic bomb
• B. Integrated Services Digital Network
• C. Email Spoofing
• D. CPU bomb

Hint:

Think of a Logic Bomb as a "digital landmine." It stays hidden and does nothing until someone "steps" on the trigger condition you have set in the code.

Answer 1

The Correct Option is A

Concept:

• Cybercrime involves malicious software (malware) designed to disrupt, damage, or gain unauthorized access to computer systems.
• Some malware is designed to lie dormant until certain specific conditions are met, making it difficult to detect immediately.

Step 1: Define a Logic Bomb
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. These conditions can be a specific date and time (often called a time bomb) or the occurrence of a particular event, such as a specific user logging in or a certain file being deleted.
Thus, option (A) is correct.

Step 2: Evaluate other options
(B) Integrated Services Digital Network (ISDN) is a set of communication standards for simultaneous digital transmission of voice, video, and data over traditional circuits. It is not malware. (C) Email Spoofing is the creation of email messages with a forged sender address. It is a technique used in phishing, not a triggered code block. (D) CPU bomb (or fork bomb) is a type of denial-of-service attack that continuously replicates itself to deplete system resources, but it doesn't necessarily rely on a "pre-defined state" or "time trigger" in the same way a logic bomb does.

Step 3: Conclusion
Based on the specific description of being "triggered on a present time or other pre-defined state," Logic Bomb is the most accurate term.
