  2. Why not make this broadcast public keys? by Anonymous Coward · · Score: 5, Interesting

    As in the "radio stations" which broadcast some OTP numbers / instructions for spies / whatever, why not make this broadcast public keys of those whom you know along with your normal traffic. Then you could run a modified Joe Sixpack in the background and gather the keys that way.

    Or broadcast DNS information (suitably protected), creating a distributed naming service without DNS servers :-)

    The motivation behind broadcasting is that if all the rest of the world is against you, your odds are so small that you will lose. But if the bad guys only get like 1 % of the rest of the world, you have a chance of winning. Supermegaprobabilisticexpialidocius!

  3. Covert Channel by espo812 · · Score: 5, Interesting

    This is known as a covert channel. Depending on what is going on this is useful or a security risk. For example, an employee could smuggle out data from a network possibly under the radar of most IDSes and the eyes of net admins. Replace employee with political prisioner, or spy, or whathave you.

  4. how about chatting over ping? by avel599 · · Score: 5, Informative

    "sonar"

    From the description of the Debian package:

    Description: console chat via ICMP (ping) echo-request packets sonar implements a peer to peer chat using ICMP (ping) echo-request packets, which means nearly stealth communication between two hosts without a central server.

    It has an ncurses-based interface with basic support for multiple windows and chats with different peers. It is a reference implementation for the u23 project of the Chaos Computer Club Cologne (http://koeln.ccc.de)
