2015-11-02 - Announcing libfilezilla

Some of the core functionality from FileZilla has been moved into libfilezilla, a new cross-platform C++ library. Check out https://lib.filezilla-project.org/ for details.

2014-05-17 - FTP over TLS support added to https://ftptest.net/

The online FTP server tester https://ftptest.net/ has been updated with FTP over TLS support. Both the modern explicit TLS negotiation as well as the legacy implicit negotiation can be tested.

The server tester can be used by server administrators and users to verify that their server has been setup correctly and in full accordance with the FTP specifications. The test tool has been specifically designed to point out even the smallest of problems, to ensure that servers passing the test are compatible with as many clients as possible.

2014-01-28 - Advisory: Malware downloads on third-party websites

As recently published on the avast! blog, modified versions of FileZilla tainted with malware are being distributed on some third-party websites.

This is by no means a new threat. While this instance is one of the largest to date, there have been many cases of modified versions spreading malware hosted on third-party websites for over a decade. We do not condone these actions and are taking measures to get the known offenders removed. Note that we cannot in general prevent tainted versions on third-party websites or prove their authenticity, especially since the FileZilla Project promotes beneficial redistribution and modifications of FileZilla in the spirit of free open source software and the GNU General Public License.

To avoid any risk when downloading FileZilla, we recommend that you only download FileZilla from the official FileZilla website or from SourceForge, the official download partner of FileZilla and many other open source projects.

To check the authenticity of your version of FileZilla, the SHA-512 hash of the unmodified FileZilla_3.7.3_win32-setup.exe is f56716044dcf1239d09343d11422b26230fb14419a4e85b702a03080550bc9e69e1c7ec22312874701de54c1ed4085e0f468d93d4993b36eabd704406b3567ff

In case you no longer have the installer, the SHA-512 hash of the installed filezilla.exe in version 3.7.3 is d6d68f564295a878ba6cdf1d79cc90b4cff4fb98177bf5aac0eb22ad3757f8997e2de718e290eb97520892d04a8d2388bb2bcb71b785d05c2b59b037abf6d28f
