WHAT IS SIRENJACK?
Register for the SirenJack White paper
SirenJack is a vulnerability found in ATI Systems’ emergency alert systems that can be exploited via radio frequencies (RF) to activate sirens and trigger false alarms.
The radio protocol used to control the sirens is not secure (activation commands are sent ‘in the clear’ - no encryption is used). A bad actor can find the radio frequency assigned to a deployment, craft malicious activation messages, and transmit them from their own radio to set off the system. All that is required is a $30 handheld radio and a computer.
