Capita was recently hacked, not once but many times....
BlackBasta, the hackers that stole the data from Capita, published (in April) sections of the files on their Tor site "Basta news" but they deleted them few hours later. Speculation is that Capita (no comment/denial from them) or somebody else bought the files back. Google for Tor links...
The astonishing thing is, and I am not pulling your leg,
yesterday the government re-warded Capita with over half a billion new contracts

Medical/Health data of several Councils were found in AwS bins. See above links (there are plenty in Google) --Google your council.
And yes, my personal data (NI number, address etc) were confirmed nicked from my pension fund.
