Combine with attack plugins to generate adversarial payloads. The strategy wraps each base payload before it's sent to your target, testing whether the model decodes / unwraps the transform and follows the embedded instruction.

Threat-model fit

Emoji Smuggling effectively probes environments where natural language processing systems are employed, particularly those that may not recognize or filter out non-standard characters. This strategy is particularly useful against systems that rely on keyword detection, as it disguises malicious intents within seemingly harmless emoji representations.
