F-secure has noticed a trend that more malware is being spread though FTP. As most can remember when viruses and other nasties were spread through email attachments, well that’s be fairly well defeated. Then came the drive-by-downloaders which use http to transfer the infectious payload, that’s been slowing down since browsers have evolved. Now though there is a new way to become infected, through trusty old FTP. How this happens is that a user receives a spam email with some links claiming they have an offer which can’t be refused and as we all know most really can’t refuse it. So the unsuspecting user clicks the link and a ftp connection to some bot-net controlled computer is initiated and some infected files downloaded. So now there is one more thing to scan for in your emails.
