Capita Plc, one of the UK’s biggest outsourcing companies, said that customer data may have been stolen during a recent cyberattack.
There is “currently some evidence of limited data exfiltration from the small proportion of affected server estate which might include customer, supplier or colleague data,” the company said in a statement Thursday.
The hack started “on or around” March 22, it added, and was interrupted by Capita on March 31.
Capita is a crucial provider of IT to the National Health Service and also helps to enforce the BBC license fee. The attack blocked internal Microsoft Office 365 applications and disrupted some clients, Capita said earlier this month.
