Friday evening many people woke up to the sound of sirens in the Dallas area and were very confused about what was going on. Many calls flooded 9-11 with questions about the sirens. An alleged hacker got into the system and set off 156 tornado sirens according to Fox 4 Dallas. These sirens are intended to warn Dallas civilians of tornadoes. The reason for this hacking and the hacker himself have not been identified but authorities are launching an investigation and will prosecute the people responsible for this.
