Keller Lenkner UK can help victims to claim compensation.

Have you been affected by the Ardagh data breach?

In May 2021, Ardagh confirmed that it had experienced a cyberattack. In response, the company was forced to shut down some of its systems as a precautionary measure. Following the breach, Ardagh ““engaged leading industry specialists to conduct a forensic investigation” into the incident.

In October 2021, the company became aware that stolen data taken from its systems had been placed on the dark web. And, in February 2022, nine months after the security breach, Ardagh wrote to employees to warn them that their personal information might have been exposed in the attack.

The following employee data was accessed in the breach (although not every employee had the same information stolen and this might not be a comprehensive list):

This is a significant amount of personal information and the delay in notifying those affected means that employees were not given the chance to secure their personal data between then and now.

As information stolen in breaches is often used by cybercriminals, this delay means that Ardagh employees have been left vulnerable to cyber fraud and scams. Anyone who was employed by Ardagh at the time of the breach should now take immediate steps to protect themselves.

Keller Lenkner UK has launched an action to help those involved in the Ardagh data security failure claim compensation for any distress or financial losses experienced because of this breach.  We strongly urge anyone affected to register with us.

Crucially, an employer cannot fire you or harm your career in any way if you make a claim. Ardagh would be breaking the law if it did so and it may be classed as discrimination.

Those affected by the Ardagh cyber-attack could be at risk

Any Ardagh employee could be involved in this breach and must be vigilant to protect against further attacks.

If your data was compromised in this incident, it could be shared on the dark web. And, while Ardagh has informed its employees that the dark web is “only accessible by means of special software” and “unlikely to be accessible by the general public” this does not lessen the risk.

The dark web is commonly used by hackers to sell data to other criminals. Similar data breaches have resulted in fraud, blackmail, and identity theft, so Ardagh employees are at high risk of being targeted by cybercriminals.

Those affected by the incident could have a compensation claim.

FAQs about the Ardagh data breach

In May 2021, Ardagh experienced a cyberattack. Following investigations, personal employee data extracted during this attack was found on the dark web.

The stolen information includes:

  • Names
  • Contact details (addresses and telephone numbers)
  • Next of kin contact details
  • Employment references
  • Salary details
  • National insurance numbers
  • Bank details including accounting number and sort code).

This might not be a comprehensive list.

If you were an Ardagh employee on (or potentially before) May 2021, you could be affected by this breach. Ardagh has a legal obligation to tell you if your information is compromised. However, it is not clear if Ardagh has told everyone affected by this breach.

Ardagh claims the delay was justified because, while it became aware in October 2021 that personal data had been placed on the dark web, it was only after further review that it became known to the business that employee data was implicated. We would question this justification.

Even if Ardagh did not know exactly what information had been stolen, it was aware that personal data was compromised. At that stage it should have contacted every single Ardagh employee to warn them that their data could be at risk and let them take steps to protect themselves from harm.


Despite some employees experiencing unusual activity (spam, phishing, etc.) since the breach, Ardagh is not taking responsibility and will not pay compensation without evidence to directly link such activity to the breach. At Keller Lenkner UK, our cyber investigators can help you uncover this evidence. We can also help you to claim compensation for any distress suffered because of the breach.

Absolutely not. An employer cannot fire you or harm your career in any way if you make a claim. Ardagh would be breaking the law if it did.

If Ardagh informs you that your data is involved in this breach, you can join our no-win, no-fee compensation claim. There are no costs to register and no obligation to proceed.

A group action claim is where a group of people – sometimes even thousands of people – have been affected by the same issue. Group action cases are also known as class actions, multi-claimant, or multi-party actions.

There are no costs to join a claim. However, if your claim is successful, you may have to pay a ‘success fee’. This fee is taken from the compensation awarded to you. At Keller Lenkner UK, our success fee is competitive, and we make sure you are fully informed about any potential costs before you officially join our action. If you lose, you won’t have to pay a penny.

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.
