The Dangers of FTP Services (Part 2)
Any user who wants to intercept a file being sent needs no special tools to open and read the file straight off the wire so to speak. Next, it is not subject to the exclusion and rights management of most operating systems which simply means it gets used anyway however strong the security of your computer system is. Older Windows operating systems designed for business deployment install the IIS automatically even if the users don’t know about it. Hackers often do probing tests to obtain usernames and passwords from data packets they manage to intercept through the FTP file transfer.
