# sshworm - example of a trusted host/key ssh worm
|
|
|
|
#
|
|
|
|
# This is extremely primitive and rarely works on anything
|
|
|
|
# but identical systems running the same versions of ssh.
|
|
|
|
# It does show how using unencrypted RSA keys for user auth
|
|
|
|
# across an enterprise can be a really bad thing. Eventually
|
|
|
|
# you should be able to let this guy go running as root on any
|
|
|
|
# given system, it will locate each user's known_hosts and
|
|
|
|
# attempt to gain accesss, reporting its path to a central system.
