SourceForge Installs Mac Malware
Believe It Or Not! SourceForge is pushing malware.
(Actually, test it yourself if you do not believe it.)
I recently installed FileZilla. During the installation process it asked me to install known malware: MacKeeper (known to corrupt OS X), PremierOpinion (former versions know to be spyware), and ZipCloud. I complained to FileZilla.
FileZilla said they could do nothing about it because SourceForge supplies the installation wrapper.
Since FileZilla is an open source application maintained on SourceForge, they use SourceForge’s installer package. FileZilla can not avoid this evil practice since they are dependent on Sourceforge’s installer. (They do have another download option that does not use an installer. I suggested they remove the SourceForge installer and use that more primitive method.)
I sent a note to security@sourceforge.net reporting that they are the scum of the earth for pushing malware. (I did not use those exact words.)
Try it yourself. (This is a safe experiment.) Download FileZilla (https://filezilla-project.org/download.php?show_all=1). Take care to answer “skip” to the malware installation requests. When you get to the real FileZilla installation page, you can quit.
