Get justice for the Hackney Council data breach


In October 2020, Hackney Council was hit by a serious cyberattack. The attack, which was announced on Tuesday 13th October, affected many of the council’s services and IT systems. 

It is currently unclear who the culprit of the attack is, and it is not yet known what, if any, data has been compromised, but online services such as One Account and payments went down.

If any resident data has been accessed by cybercriminals, this could be very damaging – both for the council and those affected.

The matter has been referred to the Information Commissioner’s Office. 

Keller Lenkner UK is considering a no win, no fee group action against Hackney Council. Group actions can be a powerful tool and can have a bigger impact than a single claim.

A statement from Hackney Council 

 A statement by Philip Glanville, Mayor of Hackney about the Hackney Council cyberattack reads:

“Hackney Council has been the target of a serious cyberattack, which is affecting many of our services and IT systems.

“Council officers have been working closely with the National Cyber Security Centre, external experts and the Ministry of Housing, Communities and Local Government to investigate and understand the impact of the incident.

“This investigation is at an early stage, and limited information is currently available. We will continue to provide updates as our investigation progresses.

“Our focus is on continuing to deliver essential frontline services, especially to our most vulnerable residents, and protecting data, while restoring affected services as soon as possible.

“In the meantime, some Council services may be unavailable or slower than normal, and our call centre is extremely busy. We ask that residents and businesses only contact us if absolutely necessary, and to bear with us while we seek to resolve these issues.”

Why use Keller Lenkner UK to make a data breach, GDPR violation, or cybercrime claim?

What can you claim for?

While each case is judged on its own merits, there are some things we would typically look for when it comes to when claiming compensation following a data breach, cybercrime or other GDPR violation:

Financial loses

With stolen data, cybercriminals can make purchases using your bank and credit cards, apply for credit in your name, set up fraudulent bank accounts and access your existing online accounts.


GDPR failures, cybercrime and data breaches can have a significant impact on you, both mentally and physically. They can cause or exacerbate anxiety, stress and other psychological conditions.

Loss of privacy

Your data has value, and organisations must be held to account if they fail to protect your right to data privacy or otherwise do not uphold your GDPR rights.

How to protect yourself following a data breach or cybercrime

  • Contact your bank or credit card provider immediately if your financial data has been exposed.
  • Check all bills and emails for goods or services you have not ordered.
  • Check your bank account for unfamiliar transactions.
  • Alert your bank or credit card provider immediately if there is any suspicious activity.
  • Monitor your credit score for any unexpected dips.
  • Call Credit, Experian and Equifax to ensure credit isn’t taken out in your name.
  • Never provide your PIN or full password to anyone (even someone claiming to be from your bank).
  • Never been pressured into moving money to another account for fraud reasons. A legitimate bank won’t ask you to do this.
  • Follow the security instructions provided by the organisation that breached your data.
  • Never automatically click on any suspicious links or downloads in emails or texts.
  • Don’t assume an email or phone call is authentic just because someone has your details.
  • Be careful who you trust – criminals often use scare tactics to try and trick you into revealing your security details.
  • Know that, even if you recognise a name or number, it might not be genuine.
  • Don’t be rushed or pressured into making a decision. A trustworthy organisation would never force you to make a financial transaction on the spot.
  • Never provide your full password, pin or security code to someone over the phone (or via message). If a bank believes a transaction has been fraudulent, they will not ask for this information to cancel the transaction.
  • Listen to your instincts and ask questions if something feels “off”.
  • Refuse requests for personal or financial information and stop discussions if you are at all unsure.
  • Contact your bank or financial service provider on a number you know and trust to check if a communication is genuine.
  • Be cautious of unsolicited communications that refer you to a web page asking for personal data.
  • Don’t accept friend requests from people you don’t know on social media.
  • Review your online privacy settings.
  • Report suspected fraud attempts to the police and Action Fraud.
  • Register with the Cifas protective registration service to slow down credit applications made in your name.
  • Change your passwords regularly and use a different password for every account (a password manager can help with this).
  • Protect your devices with up-to-date internet security software.
