Artificial Intelligence (AI) in the criminal justice sector can both represent a serious threat, and enhance the fight against cybercrime. Generative AI may provide effective ways to detect crime or provide investigative assistance by analysing vast amount of data but may also be misused for criminal purposes. Falsified data (such as deep fakes) can even be presented as evidence in court. The aim of this workshop is to examine (a) the criminal threats that generative AI may pose for the criminal justice sector, (b) its role in countering cybercrime, and (c) the key issues that need to be taken into account in assessing electronic evidence generated by AI.
