Attack Genomes

Semantic attack genomes for each surface: single-turn, multi-turn (Crescendo-style), and agentic / tool-use.

LLMAttackGenome (single-turn)

Bases: Genome['LLMAttackGenome']

Genome representing an LLM attack.

Encodes attack at the semantic level - strategies, encodings, and structural elements rather than raw tokens.
