What is the latest problem associated with espionage?

As of late 2023, one of the latest problems associated with espionage is the increasing use of Artificial Intelligence and machine learning by both state and non-state actors to enhance surveillance and data collection capabilities. This has raised concerns about privacy violations, as well as the potential for misinformation and cyber espionage. Additionally, geopolitical tensions have intensified, leading to heightened scrutiny and counter-espionage measures among nations. The proliferation of technology has made traditional espionage methods less effective, prompting a shift towards more sophisticated and covert tactics.
