Andrey Labunets
I am a researcher, I apply an adversarial mindset to problems in computer science. My current work focuses on adversarial examples and attacks against AI assistants and large language models. I work with Earlence Fernandes, and I am a part of Systems and Networking and Security and Cryptography groups at UCSD. Sometimes, I do interdisciplinary research, such as on national security letters reporting and natural language processing.
Previously, I worked as a security engineer at Facebook. Our investigation of the NSO Group exploit against WhatsApp has been featured in The New Yorker.
