Hackers set off Dallas’ 156 emergency sirens over a dozen times

Late Friday night and early Saturday morning, hackers set off 156 emergency sirens in and around the city of Dallas, Texas. According to The Dallas Morning News, the sirens began blaring shortly before midnight on Friday and were shut off and reactivated “more than a dozen times” before emergency workers shut the system down entirely at around 1:20am on Saturday morning, after confirming that there was no actual emergency and that it wasn’t the result of some benign malfunction.
