In a concerning trend, the number of successful cyber attacks against UK law firms has surged by 77% over the past year, according to a recent study. The total number of breaches rose to 954, up from 538 in the previous year, highlighting the increasing vulnerability of legal practices to cyber criminals. This alarming statistic has brought renewed attention to the need for robust cybersecurity measures within the legal sector.
Law firms as prime targets for cybercriminals
The surge in attacks is attributed to the significant value that cybercriminals place on the sensitive personal and financial information that law firms routinely handle. Chartered accountants Lubbock Fine, who conducted the study, emphasise that law firms have become prime targets for ransomware attacks and blackmail schemes. The nature of the data held by law firms—often involving confidential client information—makes them particularly attractive to hackers who seek to exploit this for financial gain.
Mark Turner, a partner at Lubbock Fine, explained the appeal of law firms to cyber criminals. “The data that law firms hold on behalf of their clients is often highly sensitive—and therefore, valuable if you intend to blackmail a law firm. This makes them a very attractive target. Hackers will often demand a blackmail payment from law firms or threaten to post that sensitive data on the internet.”
The dark web: A lucrative marketplace for stolen data
Once compromised, the sensitive information obtained from these attacks can be sold on the dark web, where there is a thriving market for stolen data. Hackers not only threaten to publish this information online, potentially damaging a firm’s reputation and client trust, but they also use it to extort large sums of money from the firms themselves. In some cases, ransomware attackers have been known to negotiate their demands, resulting in payments being made to avoid the public release of client data.
A global survey revealed that law firms are not immune to paying these ransoms, with at least eight instances in recent years where attackers were successfully paid off. This further incentivises cybercriminals to target law firms, knowing that the threat of reputational damage and legal repercussions may compel them to meet their demands.
Impact on the UK’s leading law firms
The threat of cyber attacks is not limited to smaller firms; nearly three-quarters of the UK’s top 100 law firms have reported being impacted by such breaches, according to a report by The National Cyber Security Centre (NCSC). This widespread vulnerability underscores the urgent need for the legal sector to enhance its cybersecurity protocols.
Strengthening cyber defences: A priority for law firms
In response to the rising threat, experts are calling for law firms to implement stronger cyber defences. Mark Turner from Lubbock Fine suggests that law firms require more robust protections than many other businesses due to the sensitive nature of the data they manage. “This might include segregating data across different departments, teams, and individual clients,” Turner advises. By compartmentalising data, law firms can reduce the risk of widespread access in the event of a breach, thereby minimising the potential damage.
Additionally, law firms are encouraged to regularly update their security systems, conduct thorough training for staff on cyber risks, and engage in proactive monitoring to detect and respond to threats quickly.

The dramatic increase in cyber attacks on UK law firms serves as a stark reminder of the evolving landscape of digital threats. As cybercriminals continue to refine their tactics, law firms must prioritise cybersecurity to protect their sensitive client information and maintain their reputations. With the legal sector under increasing pressure to safeguard data, the adoption of advanced security measures is no longer optional but a necessity.
As the threat of cybercrime continues to grow, law firms must remain vigilant, adapting their defences to meet the challenges of an increasingly hostile digital environment. The security of client data, and by extension, the integrity of the legal profession, depends on it.
