2001: Agentic Odyssey in Threat Modelling

“2001: Agentic Odyssey” is a hands-on, drop-in workshop where we threat model the HAL 9000 system from 2001: A Space Odyssey as if it were a modern agentic AI system (LLM + tools + permissions + side effects).I bring a HAL DFD, and together we mark trust boundaries and do classic “what can go wrong?” threat identification. Participants then split into small groups to build attack-tree branches and translate them into Fault Tree Analysis (FTA) using AND/OR logic and minimal cut sets, including lightweight probability estimates to prioritise the most likely failure chains.We finish by turning those failure paths into automation-ready test ideas (fault injection, invariants, evidence), and optionally drafting a structured HAL threat model for submission to the OWASP Threat Model Library. Designed so anyone can contribute in 10-15 minutes, while advanced participants can go deep on FTA and prioritisation. Every stage is split into a way to enable drop-ins at any time.
