If he was backdoored by a 3/4-letter and he is not skilled[1] in malware analysis how likey do you think it is that he will recover the credentials? Do you think it is as easy as: $ ls -l ~/.ssh total 80 -rw-------+ 1 nadim staff 737 Aug 22 01:39 authorized_keys -rw-------+ 1 nadim staff 35 Jan 5 21:32 config -rw-------+ 1 nadim staff 3243 Aug 18 10:57 id_rsa -rw-------+ 1 nadim staff 735 Aug 18 10:57 id_rsa.pub -rw-------+ 1 nadim staff 3326 Feb 2 21:41 id_rsa_CSIS -rw-------+ 1 nadim staff 749 Feb 2 21:41 id_rsa_CSIS.pub -rw-------+ 1 nadim staff 3198 Feb 2 21:46 known_hosts [1] I have no reason to think he does or does not posses this skill. I only mention it in the negative because it was not in his wikipedia bio.
