The NSA's RONIN is "a tool used to detect TOR-node IP-addresses." TOR is a powerful free software that enables online anonymity by directing traffic through an intricate network of relays that conceal a user's location.
The word ronin is Japanese, and it indicates a samurai with no lord or master. Many ronin became mercenaries or bodyguards while others became criminals. I don't think I need to elaborate on the humor of the NSA using the word ronin in any description of themselves. The more we learn about the NSA the clearer it becomes that they indeed serve no master.
