Please show output of these commands:
Code:
stat /lib/x86_64-linux-gnu/libkeyutils.so.1; debsums openssh-server; debsums openssh-client; debsums [whatever package contains /lib/x86_64-linux-gnu/libkeyutils.so.1]; ssh -G 2>&1
*This may work if you have Rootkut Hunter 1.4.2 though false positives may occur:
Code:
clamscan -d /var/lib/rkhunter/signatures -r /lib /usr/sbin

We've only started to determine if the server was subverted so please don't get ahead of things. If it is then realize 0) Ebury is used to sniff credentials and 1) it requires root privileges to replace root-owned files. And apart from what misguided web log and forum posts tell you about "cleaning up" a root compromise basically means Game Over.
