In February 2024, a Scottish law firm fell victim to a ransomware attack, where 155GB of sensitive client data  was stolen and shared on the dark web. Despite promptly notifying the ICO and Law Society of Scotland, and bringing in police and external IT experts, it still took weeks to rebuild their systems from the ground up. 

This wasn’t an isolated incident. In May 2024, a security consultancy reported evidence of a targeted campaign against London law firms, finding that one Magic Circle firm experienced 41 breaches of usernames and passwords in a single day.

With successful cyber attacks on UK law firms surging by 77% in recent years, the threat has never been more immediate. For Scottish practices – from Aberdeen’s commercial firms to Edinburgh solicitors and Glasgow’s legal sector – understanding these evolving threats and the vulnerabilities they exploit is the first line of defence.

Why Legal Firms Are Prime Targets

Legal practices hold a unique combination of high-value assets that make them irresistible to cybercriminals:

• Client records and case files spanning years of sensitive legal matters, including divorces, litigation, and M&A activity
• Intellectual property worth millions belonging to clients in various industries
• Financial transfer information for property transactions, settlements, and commercial deals
• Commercially sensitive business intelligence that could be exploited for corporate espionage

Cybercriminals exploit this data for identity theft, corporate espionage, and ransomware operations. But beyond the data itself, there are other risk factors:

• Deadline pressures that create urgency, making staff more susceptible to social engineering tactics
• Client confidentiality obligations that can delay reporting of incidents, giving criminals more time
• “Always-on” working culture with remote access, mobile devices, and after-hours file access creating security gaps that traditional defences weren’t designed to address

The Attack Vectors Targeting Your Practice

Phishing

Phishing attacks remain the most prevalent and disruptive type of breach, experienced by 85% of businesses. For law firms in Scotland, this threat has evolved far beyond easily-spotted scam emails. Today’s attacks are precision-crafted using publicly available information about your firm. 

Cybercriminals now impersonate clients requesting urgent document reviews, forge emails from senior partners requesting wire transfers, and create bogus court documents containing malicious attachments. 

Whaling attacks that target senior executives are particularly dangerous. These focus on managing partners and finance directors, using extensive research to craft messages that fit their specific responsibilities. The urgency and personalisation make them alarmingly convincing.

Business Email Compromise

When criminals gain access to legitimate email accounts, they bypass traditional security measures. For Scottish firms handling large property transactions or commercial settlements, a single compromised email can result in six-figure losses. 

In 2024, a County Durham firm was publicly rebuked by the ICO after criminals accessed an employee’s email and stole probate funds. Because these emails originate from genuine accounts, they evade many traditional security filters, making them especially dangerous for time-sensitive legal transactions.

Supply Chain Vulnerabilities

The legal sector’s growing reliance on technology providers creates new attack surfaces. Cloud services, document management platforms, case management systems, and payment processors all represent potential entry points that criminals actively exploit. 

Criminals specifically target technology providers who service multiple law firms, knowing that a single breach can grant access to dozens of practices simultaneously. Most firms fail to conduct thorough due diligence on third-party providers or include clear data protection clauses in contracts. Regular vendor security assessments and contractual safeguards are essential to protect against this growing threat.

Ransomware

Ransomware paralyses operations entirely. Think lost access to case files during active litigation, inability to bill clients for weeks, and systems offline while deadlines loom. Modern ransomware operators employ double and triple extortion tactics: encrypting your data, threatening to publish it, and contacting your clients directly to demand payment.

Smaller firms with limited cyber security support face increasing risk of ransomware. Criminals know these practices lack resources for sophisticated defences. The impact extends beyond the immediate attack: weeks of downtime, evaporated client trust, regulatory investigations, and costs that can be existential for smaller practices.

The Regulatory Consequences

The cyber threat to Scottish law firms isn’t just operational – it’s regulatory. 

SRA Requirements: The SRA requires firms to maintain appropriate systems and controls to protect client information and money, including proper risk management procedures and staff training on data protection responsibilities.

GDPR Obligations: Law firms must implement appropriate technical and organisational measures for data security, including encryption, access controls, and documented breach notification procedures (within 72 hours to the ICO for certain breaches).

In April 2025, one legal practice was fined £60,000 after a cyberattack led to criminals publishing highly sensitive client data on the dark web. The ICO Director of Enforcement and Investigations said, “this penalty should serve as a clear message: failure to protect the information people entrust to you carries serious monetary and reputational consequences.”

Compliance requirements like GDPR and Cyber Essentials can be complex, but they’re non-negotiable for protecting your clients’ sensitive data and maintaining trust.

Warning Signs You’re Vulnerable

How many of these scenarios sound familiar? 

• Staff accessing case files on personal devices without multi-factor authentication.
• Remote working arrangements from the pandemic that never received security review. 
• Password management through shared spreadsheets. 
• No regular cybersecurity training beyond initial onboarding. 
• Backups on the same network as primary systems. 
• Delayed software updates because you’re “too busy.”

These common practices create serious vulnerabilities. The vast majority of successful cyber attacks succeed due to human error. Despite most law firms considering cybersecurity a high priority, only a minority provide regular training to staff. This gap between recognition and action is what criminals exploit.

Taking Action Before You’re Targeted

Vulnerability isn’t inevitable. The question isn’t if threats will come – it’s whether you’ll be ready when they do.

Start with a comprehensive security audit – Assess vulnerabilities within your IT infrastructure, processes, and personnel. This gives you a clear picture of where your defences stand and where they can be strengthened.

Implement layered defences – Deploy firewalls, email filtering, endpoint protection, and intrusion detection systems that work together to catch threats at multiple levels.

Protect your backups – Keep critical data separate from primary networks and test restoration procedures regularly to ensure you can recover quickly from an attack.

Control who sees what – Deploy role-based access controls that limit data exposure based on genuine business need, reducing the impact of any single breach.

Empower your team – Invest in regular, engaging cybersecurity awareness training that helps your staff recognise and report evolving threats.
