Isn't Ericsson's switching software written in Erlang, is highly
modular and officially supports run-time code replacement (like many
COBOL systems, but unlike, say, traditional IOS)?  This means that at
least no "rootkit" is needed.  You just replace the parts of the
system you are interested in using the standard system interfaces
intended for this purpose.  Of course, the complexity of the attack is
still significant.
