Technology outsourcing company Capita has acknowledged it suffered a cyber attack last week but claimed progress in restoring client services.
The company, which counts a range of public sector organisations among its clients, released a statement that it experienced a cyber incident on Friday 31 March.
It said this primarily affected access to internal applications and that most of client services remained in operation, but some were disrupted.
“Our IT security monitoring capabilities swiftly alerted us to the incident, and we quickly invoked our established and practised technical crisis management protocols,” Capita said.
“Immediate steps were taken to successfully isolate and contain the issue. The issue was limited to parts of the Capita network and there is no evidence of customer, supplier or colleague data having been compromised.
“Working in collaboration with our specialist technical partners, including the team of leading cybersecurity experts at Microsoft Incident Response, we have restored Capita colleague access to various systems, and we are making good progress restoring remaining client services in a secure and controlled manner.”
The company’s public sector clients include the Department for Work and Pensions – for which it works on disability payment services – HM Revenue and Customs, Transport for London to manage the congestion charge, the BBC for licence fee collection and a number of local authorities including South Oxfordshire and Barnet.
