Which of the following is a potential indicator of espionage?

The potential indicator of espionage is highlighted by the unusual interest in sensitive information. Individuals engaged in espionage often exhibit a heightened curiosity towards proprietary or confidential information that is not typically relevant to their job functions. This kind of interest could suggest ulterior motives, such as attempting to gather intelligence for personal gain or external interests.

In a workplace, while curiosity can be a natural trait, an unusual fixation on sensitive topics or projects that are outside an employee's scope of work can serve as a warning sign. Monitoring such behavior is critical to counterintelligence efforts, as this type of interest may reflect attempts to compromise organizational security.

Other options might relate to general workplace behavior but do not specifically connect to the actions or motivations typically associated with espionage. For instance, frequent breaks could suggest a lack of engagement or productivity but do not indicate a desire to obtain sensitive information. Similarly, low performance could stem from various personal or work-related issues and does not intrinsically relate to espionage activities. Increased social interactions may reflect healthy workplace relationships or communication but do not inherently suggest ulterior motives toward acquiring sensitive data.
