  There's a new security threat out on the Internet, but it's not clear =
how
  much of a threat it really is. Security researchers at Internet =
Security
  Systems say they've captured the code for a sneaky new Trojan =
application
  that has installed itself on an unknown number of Internet-connected
  servers and is attempting to scan and map networks connected to the
  Internet and send that information back to its controller.

  Dan Ingevaldson, team leader for Internet Security Systems' X-Force =
R&D
  unit, says researchers are studying the Trojan--currently dubbed 55808 =
for
  its Windows size--which has been causing confusion for about a month =
in
  security circles. Security experts managed to capture their first copy =
of
  the Trojan on Wednesday, and they're still working to determine =
exactly
  what the Trojan is trying to accomplish.

  One thing is clear: Trojan 55808 is sneakier than previous Trojan =
horses.
  It doesn't self-propagate, like a virus or a worm, and requires the
  attacker to plant it on systems. But it does transmit a lot of network
  noise designed to throw off cybersleuths attempting to find the IP
  addresses of infected systems, as well as the address of the Trojan's
  writer or controller.
