The City of Columbus, Ohio confirms that hackers stole personal data of 500,000 residents during a ransomware attack.
The compromised information includes names, dates of birth, addresses, identification documents, Social Security numbers, and bank account details.
Columbus disconnected its network from the internet to thwart the attack and the ransomware gang responsible demanded 30 bitcoins (around $1.9 million) in exchange for the stolen data.
Rhysida, the ransomware gang, claims to have uploaded 3.1 terabytes of unsold data stolen from Columbus on the dark web.
