Covert Channel: ASCII Art Over ICMP

Posted by michael on from the help-i'm-trapped-inside-a-chinese-fortune-cookie-factory dept.

An anonymous reader writes "Have you ever had a particularly lossy Cisco ping, which you were sure was trying to tell you something? I mean, really *tell* you something. Echoart allows you to return a simple ascii art image in response to a Cisco-style ping."

    Now we've got to set our firewall to block pings, too, to stop that damn goatse guy . . . . what will the trolls think of next?

      I, for one, am tired of seeing that guy's ASCII.

    This means that, with the lamefilter installed, ICMP is now more advanced than Slashdot.

  9. Did this on port 23, once.. sort of. by Xzzy · · Score: 5, Interesting

    I did up a silly perl script, using curses, that ran an ascii art animation of stick figure A throwing a grenade at stick figure B.

    I, the guy that owned the machine, was figure A. The guy trying to telnet to my machine was figure B. After figure B was reduced to a crater I printed some message along the lines of "you aren't welcome here, go away".

    Ran it out of hosts.deny and left it up for quite a while. I was bored, sounded more fun than setting up a firewall like I should have. ;)

    It worked surprisingly well, even with the windows telnet client.

    to get spammed! I can see it now, pings which draw out "11VIAGRA CH3AP~!", or "`L00kING 4 L0\/3???"
