Is Woo a Korean last name?

Excuse me, could you clarify something for me? I've come across the name "Woo" in the context of individuals in the cryptocurrency and finance industry, and I'm wondering if it's a Korean last name. Now, I understand that names can have origins and meanings that transcend their cultural origins, but I'm particularly interested in the case of "Woo" as it relates to Korean heritage. So, is "Woo" indeed a Korean last name, or is it a name that's adopted or adapted from other cultures? I'd appreciate your insights on this matter.
