Employee shared our .PFX file... how bad is that?

Hey all,

An employee shared our .PFX file along with a lot of our core Powershell scripts. I am wondering how bad our risk is with loosing control of the PFX file. The PFX was created from our Enterprise Cert for our domain.

I would like to know... Is this bad enough for us to need to redo our entire enterprise security?

What other options do we have beyond rebuilding our core security?

Redo your entire enterprise security? Not necessarily. Re-issue a new private key? ABSOLUTELY! YESTERDAY!!!

Powershell scripts may provide insight into the internal structure of your environment if they're written specifically for your environment. General query scripts don't pose a threat unless they can be run on your environment which, if they have the private key, is a very real threat.

You need to shut down all outside access to your network until you can issue new certificates and perform a full security audit. You may even want to hire an outside company to do this for you. It won't be cheap but I suspect it will be cheaper than attempting to repair the damage that can be done.

Also, if you know they've taken powershell scripts and your private key you need to ask yourself what else they may have taken that you don't know about.

Side note, there's a good chance that this employee (I'm assuming now ex-employee) has violated state or federal laws. Consult an attorney and file a police report at the very least.
