The Toronto Public Library confirmed that the personal information of employees, customers, volunteers, and donors was stolen from a compromised file server during an October ransomware attack.
According to TPL, the attackers stole “a large number of files from a file server” containing data of Toronto Public Library and the Toronto Public Library Foundation employees, going back to 1998.
The library has yet to disclose what customer data was stolen and how many customers were affected by the data breach.
While the library hasn’t yet attributed the attack to a specific ransomware operation, BleepingComputer has learned that the Black Basta ransomware gang was behind the October 28 attack after seeing a photo of a ransom note shown on a TPL workstation.
