Driving past the club, we picked up the signal for a Wi-Fi-enabled combination printer and scanner that has been accessible since at least February 2016, according to a public Wi-Fi database.An open printer may sound innocuous, but it can be used by hackers for everything from capturing all the documents sent to the device to trying to infiltrate the entire network. ]
