FileZilla is an open-source FTP solution distributed under the GNU General Public License. Because the standard version is free, "cracks" or "license keys" for FileZilla are almost exclusively used as lures by malicious actors. These files typically appear on third-party sites, forums, or peer-to-peer networks promising "Pro" features or unlocked capabilities.
