New PAST2HARM attack exploits past tense to jailbreak multimodal AI

By PulseAugur Editorial · [1 sources] ·

Researchers have developed PAST2HARM, a novel jailbreaking technique that exploits a vulnerability in multimodal AI systems by reformulating prompts into the past tense. This method systematically bypasses refusal training in text-to-image models, demonstrating high attack success rates across various models like Gemini Nano Banana Pro, GPT Image 2, and SD XL. The attack can elicit a range of harmful content, including explicit material, disinformation, and hate speech, highlighting fundamental weaknesses in current AI safety measures. AI

IMPACT Highlights critical vulnerabilities in multimodal AI safety, necessitating improved defenses against sophisticated jailbreaking techniques.

    PAST2HARM: A Simple Adaptive Past Tense Attack for Jailbreaking Multimodal AI

    arXiv:2605.27545v1 Announce Type: new Abstract: Jailbreak attacks on multimodal AI systems remain underexplored, even though unsafe image generation can have more severe consequences than unsafe text and current defenses are relatively immature. We introduce PAST2HARM, a simple y…
