I have gotten a call from this number twice in two days and no voice mails to follow, and they called my cell phone. The caller ID doesn't even show a place of calling from.
Just got called and caller stated they were from SC magazine, a well known computer security magazine and wanted to know if I wished to attend their podcast. They knew all my personal information to include my personal address. I had my smart phone hooked up to my computer and suddenly my internet connection died. I called that number back, but it never rang and evidently was a bogus or spoofed number. Am glad I have life lock and hope it works because these people now have my personal information and I cannot contact them.
High probability this is a social engineering attempt to confirm personal information.
Caller ID captured the call originating from Burbank, CA.
