The keylogger attack:
- requires privileges
(the ssh key could be retrieved by breaching just the unprivileged
user account)
- can either be detected or removed quite easily
- if it only modifies memory, a reboot and the logger is gone
- if it modifies filesystem to reinsert itself after reboot
then a boot from other media would allow one to detect the
logger.
The ssh key file can be stolen without the user ever noticing.
