A large direct mail fulfillment provider has detected and locked out a number of "bots" that have tried to break into their z/OS (mainframe) FTP servers.
FTP/WatchDog-Z reports have unveiled a number of dictionary attack attempts on the company's Internet-facing z/OS FTP servers. The customer added simple RACF rules to block connection requests from the IP address of the bots, thereby eliminating any threat of either accidental break-in or denial-of-service attempts.
A search of "FTP Hack" in YouTube will display a number of detailed videos for mounting attacks on FTP servers, both manually and using free tools for automating the attack. Companies with Internet-facing FTP servers are subject to attack from the outside and need to protect themselves. FTP/WatchDog-Z makes it easy to block attacks from specific or generic IP addresses and/or IP address ranges. |
