The recent developments in the field of cybersecurity, particularly in the area of backdoor attacks, have shown a significant shift towards more sophisticated and stealthy methods of compromising machine learning models. Researchers are increasingly focusing on cross-modal triggers, architectural modifications, and dual-trigger mechanisms to enhance the invisibility and effectiveness of these attacks. The exploration of vulnerabilities in flow-based generative models and the application of reinforcement learning in financial contexts further highlight the expanding scope of backdoor attack strategies. These advancements not only demonstrate the evolving complexity of threats but also underscore the urgent need for robust defense mechanisms to safeguard against such insidious attacks.
