Aren't you struck by the irony of complaining about a 'vulnerability'
having just described a scenario in which your server has been hacked
with root permissions?

If you get hacked at that level you shut *everything* down and add them
back one at a time. That includes keys in .ssh directories along with
*all* other forms of access.
