Which of the following best illustrates technical surveillance for corporate espionage?

• A. A spy impersonates a help desk representative to obtain an employee's network password
• B. A spy hacks into a target computer and monitors an employee's communications
• C. A spy uses a phony employee badge to enter an office and take a sensitive document
• D. A spy creates a deceptive website to trick employees into entering confidential information

Answer: (B)

Technical surveillance involves using digital tools to covertly observe or capture data from computer systems and communications. The scenario of hacking into a target computer and monitoring an employee's communications demonstrates this directly, as it relies on exploiting technology to watch and collect information in real time or from stored data. The other options are examples of social engineering or physical infiltration rather than digital monitoring: impersonating a help desk rep manipulates a person to reveal credentials, using a fake badge gains physical access to retrieve documents, and a deceptive website tricks users into revealing information rather than covertly observing it.
