Get justice for a cybercrime


As our world becomes increasingly digital, cybercrime is on the rise. And the impact on victims can be devastating.

But cybercrime is preventable. And, in most cases, online theft and extortion can only happen when an organisation fails to invest in proper security to keep your data safe.

At Keller Lenkner UK, our expert data breach lawyers help people to make successful cybercrime claims against companies that have failed to protect their data from fraudsters and hackers.

The impact of cybercrime can be devastating

When most people think of cybercrime, they imagine losing money to scammers and fraudsters. And that can happen. But the impact of cybercrime is often much more complicated.

In many cases, the worry caused by having your details and identity stolen can be significant. Some victims suffer emotional stress and distress, and existing mental health conditions can be exacerbated. So, even if you don’t lose any money, the impact of cybercrime can be devastating.

What’s more, our cybercrime lawyers often see cases where financial losses or emotional trauma only start to occur months later. So the full impact of cybercrime is not always apparent and can be long-lasting.

At Keller Lenkner UK, our expert data breach lawyers are here to help you get your life back on track following a cybercrime. And we’ll help secure the maximum compensation possible to compensate for any loss and upset.

Who is at fault?

Cybercrime is on the rise. And most organisations have suffered at least one attack.

But too many companies are falling short when it comes to establishing robust data protection processes – and this is making it easier for online criminals.

So, even if an organisation has suffered a cyberattack, if it was negligent in safeguarding your data, it must be held liable.

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.
