  Exploitation techniques targeting intermediate (transit) network nodes in
public and private networks have been theoretically known and empirically
proven to work for quite some time. However, very little effort has been made
to look into the network-specific risks of compromising the Internet
infrastructure to this date. In this publication, we describe several methods
of hijacking live network traffic following a successful attack on a router or
switch. We demonstrate that modern network platforms are capable of targeted
traffic replication and redirection for online and offline analysis and
modification, which can be a threat far greater than loss of service or other
risks frequently associated with such exploits.
