Talk Intermediate 12:30 - 13:00 August 08, 2026

Adam Shostack

Threat modeling systems that call LLMs requires specialized approaches. Existing frameworks are heavyweight (wordy, jargon-laden) and often focus on threats that can only be addressed by those who train the models, offering little help to security practitioners tasked with threat modeling their company’s latest AI feature or product. This talk will introduce PHANTOM-B a new, STRIDE-like mnemonic for threat modeling LLMs. PHANTOM-B is focused on the common case of “an LLM trained by others,” rather than those training the LLM themselves.
