Technology services giant Cognizant has informed clients that the Maze ransomware attack it suffered in April 2020 resulted in personally identifiable and financial information being stolen.
On April 20, the company discovered that cybercriminals had breached its network and that the Maze ransomware was used to encrypt data on internal systems.
The incident, Cognizant said at the time, resulted in service disruption for some of its customers, but no information on the number of impacted systems was revealed.
On Wednesday, Cognizant filed with Office of the Attorney General of California copies of the notification letters it started sending to the affected customers, revealing that the attackers were able to exfiltrate "a limited amount of data from Cognizant's systems."
The professional services company says its investigation into the incident revealed that the data was likely stolen between April 9 and 11.
