How do Americans view the KGB today?

I'm curious about how the general public in the US perceives the KGB. As a Korean who has name initial KGB... I was wondering why I often get a light giggle or a surprised reaction.

When you hear "KGB," what immediately comes to mind? Is it mostly associated with Cold War history, spy movies and pop culture tropes, or modern Russian politics? Also, how much of a distinction do people usually make between the historical KGB and current agencies like the FSB?

I’d love to hear your personal thoughts, generational differences you've noticed. Thanks!
