Bristol City Council

The ransomware group wallstreet named Bristol City Council (United Kingdom) on its leak site on 27 Oct 2026. This is the group's own claim: it has not been verified by Cyfenced or Ransomware.live, and some claims turn out to be exaggerated, recycled or false.

[ What to do ]If you are a customer, partner or neighbour

  1. Be wary of emails, calls and texts that mention the organisation, especially ones asking you to pay, log in or open an attachment. Criminals use leak-site claims to make phishing believable.
  2. Check announcements on the organisation's own website or official channels, not on social media reposts.
  3. If you share accounts or systems with the organisation, change those passwords and check for unusual logins.
  4. Never visit leak sites or download files claimed to come from the attack: they can contain malware, and handling stolen personal data can be illegal.
