In this paper, we propose a new methodology for adversarial prediction in the field of green security, called conditional diffusion model. We exploit the diffusion model to overcome the limitations of conventional Gaussian process or linear model-based approaches and to capture complex behavioral patterns. This approach integrates game-theoretic optimization and diffusion models, and proposes a 'mixture of mixed strategies' and a modified sequential Monte Carlo (SMC) sampler to address the constraints of the mixed strategy space and the sampling problems from non-normal distributions. We demonstrate the effectiveness of the proposed method through experiments using synthetic and real poaching datasets.
