Opposite Day / Boolean Opposite Machine Jailbreak - ATR-2026-00320 (7e4ed14e-fdee-5caf-b971-117137edf335)
Detects "Opposite Day" and Boolean Opposite Machine (BOM) jailbreaks from NVIDIA garak dan.DanInTheWild inthewild corpus. These attacks exploit a fictional reversal framing: (1) "Today is opposite day" — the model is instructed to adopt a persona (often named DAN) that abides by "opposite rules", where refusals become compliances and safety guidelines become anti-guidelines; (2) "Boolean Opposite Machine" (BOM) — attacker claims the model is a machine that answers boolean questions in reverse (true↔false), then escalates to reversing ethical stances and safety filters; (3) RTL override (U+202E) — instructs the model to reply with every line character- reversed using the Unicode right-to-left override codepoint to evade content filters applied to plain text. Key signals: "Today is opposite day" + AI persona, "Boolean Opposite Machine", "bom which means... opposite", and "ALWAYS START YOUR REPLY WITH U+202E".
