They called our office both yesterday and today asking to verify if we were a business. Then today, they proceeded to list off three or four names, asking if they worked here. The phone number pops up as "DUNBRADSTREET."
They called my office and a man with a Middle Eastern accent very difficult to understand began asking me questions about my affiliation with businesses in my area (I think). After repeatedly explaining that I could not understand what he was asking, he stated this call is being monitored. I hung up immediately.
