Ransomware Claims

Make a no-win, no-fee ransomware claim with our experienced cybercrime lawyers. 

Get justice for a ransomware violation


A ransomware attack happens when criminals infect an organisation’s systems and prevent or limit access unless a ransom is paid. Ransom may also be requested to stop the criminals releasing sensitive data into the public domain.

Finding out that your personal data has been held hostage in a ransomware violation can be extremely distressing. Especially where you trusted an organisation to look after it.

To make matters worse, if this information is eventually breached, it may be used to commit further crimes against you. So it’s no wonder that people commonly suffer emotional anguish, anxiety and stress after a ransomware data hack.

At Keller Lenkner UK, our data breach lawyers help people to make successful ransomware claims to compensate for their loss and distress. Where enough people come forward, we do this by launching a group action case.

Ransomware compensation after a data breach

You might be eligible for ransomware compensation if an organisation has failed to protect your personal data.

Stolen data is easy to buy on the dark web, so if you are the victim of a ransomware violation, it is quite likely that different criminals could be trying to use your data against you.

Stolen data is also used in batches over time, so the impact of a data hack might not be immediately apparent.


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.

Are organisations doing enough to protect customers from data breaches and cybercrime?


In many cases, data hacks and cyber-attacks happen because of a failure to implement reasonable and robust processes. Often because of the cost needed to do this.

But, by not putting adequate processes and training in place, organisations are leaving customers open to an increased risk of cyber scams and avoidable mistakes that lead to data breaches.

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.
