sounds like you might have been accessed by your logs being
deleted..if i were you i would scan for a trojan..and take steps to
remove it if found.

also change your password and install a anti hammer..blocks login
after 3-4-5 failed attempts if that was how they gained access...also
check your up to date with patches

check for any obscure files , folders, scripts etc

also from your logs data (from day 1 of suspected attack)... do a
search for files created on that date.
