SCAM CALLING ABOUT TROUBLE ON YOUR NETWORK, SERVER PROVIDING SOME ERROR OR SOME JUNK.

I thought it was funny as he was calling me, at the Cyber Security group for the company i work for.  Too funny, He asked for info and simply responded with if you are a network admin then you have that information and don't need it from me.  Then I simply asked him the who he worked for, the company name and who he thought he was talking to based on obtaining my user ID from the server, he obviously could cross reference it to my name and location.  He then challanged me with. "Where are you calling from"  I pointed out the fact he called me and recommended he hang up.
