New Jailbreak Uses Dual-Layer Encoding to Reconstruct Blocked Prompts Past Moderation

The RoguePrompt method encodes a disallowed request so the model itself rebuilds it during generation, bypassing the moderation layer meant to catch it.

A security preprint describes a prompt-based attack that targets the gap between what a moderation filter sees and what a model reconstructs. RoguePrompt uses a dual-layer encoding for self-reconstruction. The input is encoded so that safet…

The LLM Jailbreak and Moderation Arms Race

Attackers keep finding encodings that pass input moderation while the model reconstructs the blocked intent, forcing safety controls to move from input filtering toward output and trace inspection.
