FileZilla Hacked

February 3, 2014 by Eric and Steve

If you use the popular FileZilla program, please read this entry carefully.

FileZilla is a program many people use to copy files from one computer to another. The industry jargon is "FTP" or "File Transfer Protocol".

On January 27th, security researchers at Avast Software discovered that hackers have modified FileZilla for nefarious purposes. Specifically, the hackers changed the program in such a way that it would send any username and password you entered to a collection server located in Germany and reportedly controlled by parties in Russia.

After modifying the program, the hackers placed their malicious version on distribution servers around the Internet. Unsuspecting users may have downloaded and installed the hacked version, in the process revealing their security information to these bad guys.

Unfortunately, although researchers only discovered the problem last week, the hacked version of FileZilla was originally created and distributed at least eighteen months ago.

What Should You Do

If you downloaded or use FileZilla, we recommend you:

  1. Uninstall FileZilla immediately
  2. If you want to continue to use FileZilla, download a good copy from their, and only their, official website:
  3. If you want to use a different FTP program, we recommend SmartFTP for Windows or Transmit or Flow for Mac
  4. Contact the owners of any computer you access via FileZilla and ask them to close your old account and create a new username and password for you
