What is a potential sign of espionage related to wealth?

Unexplained affluence can be a potential sign of espionage because it indicates that an individual may possess wealth or resources that cannot be accounted for through legitimate means. This might suggest that they are receiving financial support from foreign entities or engaged in illegal activities, such as passing sensitive information or trade secrets in exchange for monetary gain. In the context of counterintelligence, being vigilant about individuals whose lifestyle and expenditures significantly exceed what their salary or known financial situation would suggest is crucial. Such discrepancies may represent a way for foreign intelligence operatives to heavily compensate someone for access to valuable information or services that could be detrimental to national security. Recognizing and reporting these signs helps organizations protect themselves from potential espionage threats.
