Phishing attempts and suspicious activity were detected on the city’s network around 5 a.m., New Orleans chief information officer Kim LaGrue said during a press conference. By 11 a.m., technician investigators detected “a cybersecurity incident” and the city’s information technology department began powering down servers and city computers as a precaution, the New Orleans Office of Homeland Security and Emergency Preparedness said in a series of tweets.
While ransomware was detected, no ransom has been demanded in the cyberattack, Cantrell said.
At this time, the city does not believe any employee information was compromised during the phishing attempts that occurred.
The incident is being investigated by the city with assistance from the Louisiana State Police, Louisiana National Guard, the FBI and Secret Service, according to the tweets.
The city’s 911 system was not affected by the attack, the city said.
