The definitive UK data breach and cyber attack list

In the pages below we list every cyber attack and data breach reported in the UK, classified by incident type according to the following categories:

  • Ransomware - An incident where ransomware is specifically stated as the cause.
  • Data Breach - An incident where data has been breached, lost or stolen. 
  • Denial of Service - An incident where a service or website has been taken down.
  • Phishing - An incident where a large amount of UK consumers, or significant individuals such as politicians, have been phished.
  • Hacking Incident - An incident which does not fit any of the other categories, or where the detail is unknown.

Where an incident fits more than one category, we use the highest category in the list.  E.g. a ransomware attack that is also a data breach would be categorised as ransomware attack.

As we list the very first reported news story for each incident you may be able to find more detail by searching for later reports.  We use information from all reports to categorise each attack or breach.

Please share any feedback you may have.
