Yellow Pages Group, a Canadian directory publisher has confirmed to BleepingComputer that it has been hit by a cyber attack.
Black Basta ransomware and extortion gang claims responsibility for the attack and has posted sensitive documents and data over the weekend.
Granted, directory services like Yellow Pages largely collect and provide public data, that does not imply they possess no personal or private corporate data.
“Based on our investigation to date, we have reason to believe that the unauthorized third party stole certain personal information from servers containing YP employee data and limited data relating to our business customers.”
Based on the dates present on the few leaked documents seen by BleepingComputer-specifically most recent ones, it appears the cyber attack occurred on or after March 15th, 2023.
Earlier this month, Black Basta had claimed responsibility for cyber attack on Capita, UK-based professional outsourcing provider.
