Introduction Although AI technologies have been around for several decades, the advent of ChatGPT has demonstrated in a tangible way the truly immense possibilities for AI-driven human-machine collaboration – both for legitimate purposes and for illicit aims. Criminals are beginning to utilize AI bots powered by Large Language Model (LLMs), such as ChatGPT, to accelerate their criminal activities. This eBook will explore the resulting challenges created for law enforcement, as well as how investigators and analysts can leverage LLM technology to stay one step ahead. Since being released to the public on Nov. 30, 2022, ChatGPT has been adopted at a stunningly fast pace, with 206.7 million unique visitors generating 1.76 billion visits during April 2023 1 . While it took TikTok nine months following its global launch to reach 100 million users, ChatGPT crossed this milestone within two short months 2 . This incredible growth rate represents the fastest ramp- up in history of a consumer internet app, other than Meta's Threads app which leveraged Instagram's existing user base, and further reinforces the importance of law enforcement closely monitoring this phenomenon.
