Is Kazaa still working?

Hello there, I'm curious about the status of Kazaa, the peer-to-peer file sharing software that was popular in the early 2000s. Do you know if Kazaa is still operational and in use today? I've heard that it faced some legal challenges and was eventually shut down, but I'm wondering if there are any clones or alternatives that have taken its place. Additionally, I'm interested in knowing if there are any security risks associated with using Kazaa or similar services, especially considering the sensitive nature of digital files being shared. Can you provide me with some insights on these matters?
