Called in the main line asking for internal information. Telemarketer/Social Engineering attemps trying to attain SSL certificate information.

A "Chris" called and asked, "May I please speak to your IT manager?"
I replied, "We are an IT company. What is the call regarding?"
[Pause]
Chris: "...I need to inquire about the SSL Certificates that will be expiring soon for your company's website."

I guess he knew that I was about to hang up on him.

Keep getting both calls and emails from this "Chris" person. Sounded like a real used car saleman. Gave me the whole “great deal, save money” spiel. Told him I’d look into it and call him back later.
