Sometimes when I try to FTP to a secure server, I get a message warning me of a “959 dropdown attack” and the connection gets terminated. Whats going on?
(top) A: This warning prevents hackers from mounting a special kind of attack that exploits the fact that SafeTP transparently supports both secure and insecure FTP servers. The warning indicates that you’re connecting to a server which SafeTP knows to be secure (from a previous connection) but which is now behaving like an insecure server. For example, if you’ve previously connected to secure SafeTP server at port 353 of IP address X, and are now connecting to an insecure FTP server on port 21 of the same IP, you will see this warning of a potential attack. If you’re certain that you’re connecting to the correct port, it’s possible the server no longer supports SafeTP, although this is pretty unlikely and should be verified through other channels. If you’re certain this is the case, you can stop the warning by deleting the corresponding server key in the SafeTP Manager.
