Joey Melo, AI Red Teaming Specialist, CrowdStrike, speaks at [un]prompted 2026 on: The Parseltongue Protocol: A Deep Dive into 100+ Textual Obfuscation Methods.

Large Language Models are designed with robust multilingual and multi-encoding support, but this versatility creates a new security vulnerability. This talk presents the results of a systematic empirical study where 100+ encoding and encryption techniques where used against 9 leading AI models with over 17,000 malicious prompts, revealing significant gaps in current AI safety systems. Attendees will gain critical insights into the evolving prompt injection attack surface and learn which encoding mechanisms pose the greatest threat to LLM security.
