New Orleans declared a state of emergency and shut down its computers after a cyber security event, the latest in a string of city and state governments to be attacked by hackers.

Suspicious activity was spotted around 5 a.m. Friday morning. By 8 a.m., there was an uptick in that activity, which included evidence of phishing attempts and ransomware, Kim LaGrue, the city’s head of IT said in a press conference. Once the city confirmed it was under attack, servers and computers were shut down.
