The City of Dallas ransomware attack victimized nearly 300 more people than what was initially disclosed, according to City officials.
City spokesperson Catherine Cuellar told The Dallas Morning News on Wednesday that the City’s internal investigation into the May 3 ransomware attack has determined that an additional 293 people may have had their personal data obtained by hackers. Names, addresses, social security numbers, and other sensitive information were absconded by the hackers.
Cuellar said data from City employees and Dallas residents was taken and that the City notified affected individuals via letter.
This disclosure adds to the number of more than 30,000 people whose personal information has been leaked, as reported by DMN.
In August, a data security break report from the Texas Attorney General revealed that over 26,000 people, including children, had their data compromised, as reported by The Dallas Express.
After the ransomware attack, the City spent upwards of $8 million on recovery efforts and additional cybersecurity measures. Cuellar told DMN that the IT department does not intend to ask the City Council for more funds in response to the attack.
A report obtained by DMN said that the cyberattack impacted every City department and that the attack shut down at least 17 systems.
These systems reportedly included police and fire mobile data computers, fire station alert systems, public safety file sharing, police surveillance cameras, the court-ordered warrant management system, the building permitting system, city fax and print services, the library management system, and the electronic pay system for residents to pay bills to the City.
A spokesperson from the FBI Dallas office declined to share whether the agency’s investigation into the ransomware attack was ongoing.
