Cyber criminals are using Voice over Internet Protocol (VoIP) platforms to launch vishing attacks against employees worldwide, the FBI warned on Jan. 14. Vishing means voice phishing, an attack in which threat actors use phone calls instead of emails to try to trick the person on the other end into allowing access to their accounts. The attackers targeted all employees, not just those in top roles who might have greater access. With these tactics you can decrease the chance of VoIP scams opening a door into your network.”]
