London-based professional outsourcing giant Capita has published an update on the cyber-incident that impacted it at the start of the month, now admitting that hackers exfiltrated data from its systems.

On March 31, 2023, Capita disclosed an IT issue that impacted its services.

At the time, Capita did not provide many details about the nature of the cyberattack.

On April 17, 2023, the Black Basta ransomware gang posted Capita on its extortion portal on the dark web, offering to sell stolen data to interested buyers unless the victim paid the ransom.

The company did not provide public comment on the allegations of the Black Basta hackers and has not mentioned anything about ransomware in its recent statement, so the validity of these claims remains unconfirmed.

BleepingComputer has contacted Capita to request a comment about Black Basta’s allegations and whether or not they have communicated with the threat actors, but a spokesperson declined to provide an answer.
