Large language models in digital forensics: capabilities, challenges and future directions

The rapid advancement of large language models (LLMs) has simultaneously created opportunities and challenges for digital forensic science. This survey systematically examines the emerging intersection between generative artificial intelligence and digital forensics through our analysis of 33 peer-reviewed works. We map LLM capabilities across the established Digital Forensic Research Workshop (DFRWS) process model, identifying three strategic integration points where these technologies demonstrate measurable benefits – pattern recognition during the examination phase, evidence analysis during the analysis phase, and evidence presentation and reporting during the presentation phase. Our findings show that LLMs achieve substantial performance improvements across diverse forensic tasks, but critical challenges persist, including the fundamental tension between the probabilistic nature of LLM outputs and deterministic forensic requirements, alongside concerns regarding explainability, reproducibility, and legal admissibility. We identify significant research gaps in validation frameworks, forensic-ready architectures, and standardised evaluation protocols. The survey establishes a comprehensive research agenda spanning technical, methodological, and legal domains, emphasising the necessity for interdisciplinary collaboration and human-AI collaborative approaches to preserve forensic integrity when leveraging LLM capabilities.
