Hi.
Today we got a phone call supposedly from a company in San Diego that said they were getting peculiar messages from our devices and that they needed to have us examine some of our settings. Both the technician and his supervisor had heavy accents. I told them to speak to our ISP (they knew it was Sonic) and they got indignant. They finally gave me a call-back number, in what they claimed was the San Diego area, which I passed on to Sonic. We have Sonic's Fusion phone service, and Sonic confirmed that the caller was not calling from the number they gave me, but had somehow spoofed the number to "2001."
This was apparently a human-call phishing attempt--I don't know if they are targeting Sonic customers specifically. I suggest you refuse to cooperate if you get a similar call and insist they communicate with your Internet Service Provider if they have security issues or concerns.
