We have a number of servers (100+) that we need to increase a certain type of security on. (sortof internal, sorry NDA).
We have thought about using a rootkit of some sort that would be able to keep us access if the main root password has been compromised. It is a time sensitive problem (think high SLA).
What we are after is a script that can take a server and password list and add this backdoor to. We have other software to automate other things, but not this unfortunately.
This is NOT a fishing or hacking goal, we own and have full rights to said servers, we just don't know much about scripting or backdoor type stuff :/
