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:
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.
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.
In October 2025, it was discovered a cyberattack had taken place – compromising the personal data of customers of car manufacturer Renault and its sister brand Dacia.
In what appears to be a significant cyber security incident, Renault UK has confirmed unauthorised third parties have accessed the data of thousands of customers.
Renault released the following statement after the breach: “One of Renault Group UK’s third-party data processing providers has notified us that that they have been the subject of a cyber-attack, and that some customers’ personal data has been taken from one of their systems.
This includes some or all of: customer names, addresses, dates of birth, gender, phone number, vehicle identification numbers and vehicle registration details.
No financial or password data has been compromised.
The third-party provider has confirmed this is an isolated incident which has been contained, and we are working with it to ensure that all appropriate actions are being taken. We have notified all relevant authorities.
No Renault Group UK systems have been compromised.
We are in the process of contacting all affected customers, advising them of the cyber-attack and reminding them to be cautious of any unsolicited requests for personal information.
We wish to apologise to all affected customers. Data privacy is of the upmost importance to us and we deeply regret that this has occurred.”
