About Cypurr

We’re a small cryptoparty and cat-enthusiast collective. We’ve held digital security workshops all over NYC, including the New York Public Library, Brooklyn Public Library, Bluestockings, Babycastles, and more over the past four years. We are a member of the Electronic Frontier Alliance


To educate the public on cybersecurity in an accessible and hollistic way with fun cats. Our work aims to resist systemic oppressions through community self-defense
