Ref Link : http://secer.org/hacktools/0day-openssh-remote-exploit.html Securing the sshd of your customer's servers ASAP by following atleast the following steps. 1) Change Default SSH Port 2) Disable Direct Root Login 3) Disable common wheel users like admin. Use a hard to guess wheel username 4) Disable shell access for all customers. 5) If possible allow access to SSH only from Bobcares and Customer's ip address ( Use firewall and hosts.{allow,deny} file to do this. ) Step 1, 2 and 3 makes it hard for the users to guess ssh port and wheel username Step 4 prevents user accounts from getting hacked. Step 5 make it almost 100% fool proof unless someone from own network or the client's network tries to hack.
