A host of government websites are running a power-pinching program from visitors’ computers to mine cryptocurrency, a process known as “cryptojacking“. 

Thousands of websites, including the Information Commissioner’s Office, the Scottish NHS helpline and the Student Loans company along with hundreds of other central and local government sites appear to have been hijacked by hackers to mine cryptocurrency like Bitcoin or Ethereum.
