Data Breach
Year in Review 2023

A message from Kingsley Hayes

Kingsley Hayes bio image

In 2023, we have continued to witness a tumultuous landscape of cybersecurity breaches, with many high-profile organisations affected, including Arnold Clark, Capita, Cambian, Parasol, The Metropolitan Police, and more. With a growing prevalence of ransom demands by hackers, and threats to release sensitive personal data onto the dark web, millions of individuals are at risk.

A true data protection champion, we acted promptly and proactively to address the aftermath and implications of these breaches, offering legal counsel and support to affected parties where appropriate, and emphasising the critical need for immediate protection. In particular, we were delighted to successfully settle our hard-fought claim against Equifax this year, securing compensation and justice for thousands of affected clients.

Over the past twelve months, in addition to representing clients in various data breach class actions, our team also attended industry events such as the CORLA Annual General Meeting, further solidifying our commitment to collective redress and access to justice. We also achieved significant legal commentary in key publications, as our data protection experts provided valuable insights into the implications of cybersecurity incidents, data protection fines, and regulatory gaps.

Our high-profile data breach and cybercrime claims following breaches at British Airways, EasyJet, Equifax, Ticketmaster and Equiniti were pivotal in establishing our firm’s rankings in both the Legal 500 and Chambers and Partners. Such recognition speaks volumes about our firm’s approach and our prowess in advocating for clients against well-resourced entities. On a personal note, I was delighted to be recommended in the Legal 500 this year.

For more detailed insights into each month’s specific legal actions, developments, industry recognitions, and ongoing efforts in addressing cybersecurity incidents, please refer to the respective sections within this report.

HEAD OF DATA & PRIVACY LITIGATION 

January 2023

Staff at the Guardian had personal and confidential information accessed in a sophisticated cyberattack.

The compromised data included the names, addresses, bank account information, salaries, and passport documents of Guardian reporters.

Hackers targeted Arnold Clark and demanded that the car dealer group pay a multi-million-pound ransom.

If they were not paid, the cybercriminal said they would upload customer information to the dark web. Tens of thousands of people were thought to be at risk.

JD Sports experienced a cyber-attack that put ten million customers at risk.

According to the sportswear chain, hackers may have accessed customer names, addresses, email accounts, phone numbers, order details, and the final four digits of customer bank cards.

Air France and KLM customers had their accounts hacked

According to a statement by Air France and KLM, customers of these two airlines had their accounts breached when hackers managed to break into the Flying Blue loyalty program.

We warned victims of these data breaches that they were at high risk of being targeted by cybercriminals and advised that they take immediate steps to protect themselves.

Lagan Specialist Contracting Group (SCG)

In February 2023, Lagan SCG – a Belfast headquartered construction business – experienced a data breach following a cyberattack.  A significant amount of sensitive and confidential employee data was compromised because of the hack and later found on the dark web.  

In May, we launched a group action to find out how this data privacy breach was allowed to happen, and how the security incident affects Lagan SCG employees. We encourage affected employees to join our action and claim compensation for the failure to protect their data. 

Capita

In March 2023, Capita experienced a ransomware cyber-attack. Following the security incident, criminals exfiltrated some data from Capita’s servers. Over half a million UK pension holders could be affected by this data security incident.  

The second data breach involves benefits data which was uncovered on publicly accessible “unsafe storage” provided by Capita. This data security incident is believed to affect several local authorities including councils in Colchester, Coventry, Derby, Adur and Worthing, Rochford, and South Staffordshire.  

Our cyber experts are investigating these breaches to find out what happened, which pension plans and local authorities are involved, and how the breaches affect victims. 

Cadwalader Wickersham & Taft LLP

New York-founded law firm Cadwalader, Wickersham & Taft experienced a cyberattack leading to a data breach. And, according to a proposed class action in the US, the firm is at fault for exposing personal data.  

In the US, victims of this breach are being urged to join the class action and claim compensation. It is thought that more than 93,000 people could have had their personal data compromised in this attack.  

As Cadwalader, Wickersham & Taft is a large international law firm, we would urge UK-based clients affected by this breach to sign with us, as we look to launch a no-win, no-fee group action compensation claim in England & Wales.

How we help you...

Data breaches caused by human error

As a direct result of admin errors and poor data security processes, privacy violations are causing considerable distress, upset, embarrassment and harm. The consequences of these errors are often far-reaching, and you have a legal right to hold the guilty party to account. 

Data breaches caused by cybercrime

Too many companies fall short when it comes to data security. This makes it easier for criminals to exploit your data. We help people make successful cybercrime claims against companies that have failed in their data protection responsibilities.

Technology privacy violations & abuses

The ugly truth is that big companies are collecting and misusing personal data in many different ways. But you can claim compensation if a company has breached your data protection or privacy rights. 

Cryptocurrency/NFT breaches

Even if you get your money back, the impact of cryptocurrency breach can be devastating. Our cybercrime experts help to recover losses where crypto/NFT fraud can be linked to a data breach or hack. 

Data Breach, GDPR & Cybercrime Group Actions

Our expert data protection lawyers have all the legal expertise needed to take on corporate giants and large organisations and win. In addition to our own legal know-how, we also work with expert barristers to help us win our group action cases.
