Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, which agencies have been notified by Deloitte that their data may have been compromised following a cyber attack.

Deloitte notified the National Cyber Security Centre (NCSC) to a cyber incident affecting their US
operations in September 2017.

Based on current information, there is no indication of impact to the UK branch of the organisation,
which operates a separate infrastructure to their American counterparts. The NCSC are working
with partners to better understand the threat and identify any mitigation measures.
