Has there been any cases where hackers have taken over the phone number to a business, by creating a phone number in the same area code, setting up a virtual PBX / Asterisk system, routing all calls to the business, recording the conversations, and updating/hijacking Google/Bing/Yelp listings for the business with their own phone number?
I've run into at least two businesses who I've confirmed their number, and both have said "That's not our number.", yet I was able to reach them. One was an insurance agency and another was a process server. I'm guessing someone may be able to record the conversation and extract credit card numbers or CCV numbers. Not every small business is up-to-date with their online listing.
