MAS prompt injection risks and mitigation strategies detailed

By PulseAugur Editorial · [1 sources] ·

This article discusses advanced prompt injection techniques targeting Multi-Agent Systems (MAS) where instructions can be hidden within tool results, such as web pages or database entries. It explains that traditional prompt injection defenses are insufficient because models are trained to follow instructions regardless of their origin. The author proposes several mitigation strategies, including delimiting and labeling untrusted data, sanitizing inputs, minimizing returned data, and implementing policy filters at the agent layer before the model acts.
