Why law firms are prime targets for cyberattacks
Cyberattacks targeting law firms are more common than you might realize. One survey found that 29% of lawyers had experienced a security breach at their firm, while 19% were unaware of whether a security breach had ever happened.
Here’s why cybercriminals often target law firms in their attacks.
High-value data
Law firms work with a huge volume of sensitive data as part of their day-to-day operations. They often collect personally identifiable information from clients and include sensitive details in client communications.
On top of that, case files often contain financial records, intellectual property, and other pieces of information that cybercriminals find valuable.
If hackers access this information, they can use it for some nefarious purposes. Stealing personal client information allows them to conduct identity theft. Stealing business data gives cybercriminals access to confidential intelligence, which they can use to find insider trading opportunities or conduct financial fraud.
Perceived vulnerabilities
Cybercriminals often perceive law firms as being more vulnerable than larger corporations. In some cases, this is a misconception, but many law firms do have significant security lapses that make them vulnerable to cyberattacks.
For example, many law firms are small organizations that have very limited IT budgets. This means they may not have many dedicated IT professionals on staff, if they have any at all. On top of that, many law firms rely primarily on traditional security methods, rather than the most up-to-date strategies.
These perceived vulnerabilities make you more vulnerable to hackers while simultaneously discouraging potential clients from working with you. 40% of legal clients would consider firing a firm that had experienced a data breach.
Specific threats targeting law firms
Here are some of the most common attack vectors that hackers use to target law firms:
- Phishing: Hackers pose as trusted contacts with phishing attacks, tricking you into revealing secure information.
- Ransomware attacks: This form of malware steals your organization’s files, demanding a large ransom payment to return them.
- Business email compromise: Hackers create fake email addresses to pose as a trusted business partner and use them to facilitate fraudulent transactions.
- Insider threats: A member of your legal team could expose sensitive information, whether maliciously or on purpose.
- Software attacks: A cyberattack targeting a software platform you use could expose sensitive information.
Legal and ethical obligations
Despite these threats, law firms have both legal and ethical obligations to protect the data they work with.
US firms need to adhere to the American Bar Association (ABA) model rules, as well as regulations from their local bar associations. If you work with international clients, you may also need to adhere to the GDPR and other global data protection standards.
Failing to adhere to these standards will have severe long-term consequences for your organization. If you experience a data breach, you could be subject to fines and lawsuits, and you will likely experience significant damage to your reputation.
Law firms aren’t just encouraged to take cybersecurity seriously, they’re required to. Depending on where your firm operates and the types of clients you serve, you may be subject to several data protection laws and professional standards. The table below outlines some of the key regulations law firms must comply with:
| Regulation | Who It Applies To | What It Requires |
|---|---|---|
| ABA Model Rules (US) | All US-based law firms | Duty to safeguard client information under Rule 1.6 |
| State Bar Regulations | Law firms by state | Varies by jurisdiction; often includes breach notification rules |
| GDPR (EU) | Firms with EU clients or operations | Requires lawful processing, data minimization, and breach reporting |
| CCPA (California) | Firms handling data of California residents | Consumer rights, data access requests, and opt-out options |
| HIPAA (US, Health Law Firms) | Firms dealing with health data | Strict protection of health-related personal data |
Essential cybersecurity measures for law firms
Although cyber threats can be devastating for law firms, there are steps you can take to protect your organization. Here are the must-have cybersecurity measures all law firms should use.
Strong password policies and multi-factor authentication
Access control should be a major priority when configuring your law firm’s systems. Reliable access control strategies keep cybercriminals out and ensure that only authorized users can access your systems.
This starts with requiring all system users to have strong passwords. These passwords should not be easy to guess, and should use combinations of uppercase and lowercase letters, numbers, and symbols for added complexity.
All passwords should be stored securely in a digital password manager and should be changed immediately if unauthorized access is suspected.
In addition to passwords, you should implement multi-factor authentication for an extra layer of security. Multi-factor authentication requires users to enter a third piece of identifying information in addition to their username and password. This is usually a code sent to the user’s phone or email.
Secure network infrastructure
Think of network infrastructure as a fortress around your law firm’s digital systems. The first step to building a secure network is to implement a strong firewall. You’ll also need to install an intrusion detection system so you can respond to security incidents as soon as they happen.
Another key component of secure network infrastructure is network segmentation, which involves isolating different sections of your network. This way, if someone hacks one component of your network, they won’t be able to access the entire system.
Finally, your team will need to use a secure Wi-Fi configuration, both in the office and when working from home. This helps prevent threat actors from hijacking your network to launch attacks or steal personal data.
Endpoint security
Endpoints are the devices you use to access your law firm’s network, such as desktop and laptop computers, smartphones, and tablets. This is particularly important for legal professionals who work remotely and may use personal devices for work.
Each endpoint should have robust security measures for added security. Most notably, up-to-date anti-virus and anti-malware programs should be installed on all devices. Legal teams should also use endpoint detection and response (EDR) platforms, which provide advanced threat monitoring for all connected devices.
Every endpoint your team uses should undergo regular patches and updates to stay safe. This includes updating the software programs you use as well as updating the operating system itself.
Data encryption
Encryption technology uses cryptography to scramble your data, so even if hackers intercept it, they won’t be able to read it. Data should be encrypted at rest in your systems and while it’s in transit during online communications.
Opt for software programs that come with encryption features, especially when working on laptops or mobile devices. Your cloud-based data storage should also be completely encrypted.
Regular data backups and a disaster recovery plan
Law firms should back up their data regularly. This ensures that even if your systems are breached or affected by a natural disaster, you’ll still have extra copies of your data.
When backing up your data, use a different storage method than you would use for your primary systems. For example, if you use cloud-based systems as your primary data storage method, use on-premise hardware for your backups, or vice versa.
Access control and least privilege
Law firms should adhere to the principle of least privilege when configuring their access controls. This means that each employee should only have access to the parts of the system they need to do their jobs.
Set up each user’s account individually and configure their access level based on their role. Conduct regular reviews of your access controls and update them based on changes in your organization. For example, you may need to increase access when a team member gets promoted, or temporarily remove access for someone taking a leave of absence.
Building Cyber Awareness at Your Firm
When your law practice has a security-first culture, you’re less likely to be a target for cybercrime. Train employees to follow security protocols to work as securely as possible with thorough training, clear policies, and incident reporting options.
Comprehensive cybersecurity training
Sometimes, one employee error is all it takes to compromise your data security. That’s why all employees should receive cybersecurity training on a regular basis, regardless of their role in the organization.
Training should cover key topics such as how to create a secure password, how to work with confidential information, and how to keep mobile devices safe. Employees should also receive training on how to spot and avoid phishing and other social engineering attacks.
Since new cyber threats emerge regularly, schedule training sessions regularly to keep employees up-to-date. You can also use simulated phishing attacks and other evaluations to assess your team’s security knowledge.
Clear data handling policies and procedures
Create clear cybersecurity policies for your team so they know exactly how to handle sensitive information.
These policies should specify when and when not to access and share client data. Policies should also specify how to store and dispose of client data to limit exposure. These policies should eliminate any ambiguity regarding data handling processes.
Law firms should also have policies specifying when employees are allowed to work remotely and when they are allowed to use personal devices. For example, employees may be allowed to work from a laptop only if they have appropriate anti-virus protection and are using a VPN for a secure connection.
Incident reporting procedures
Encourage employees to report any possible security incidents to IT leadership, no matter how small. Establish clear protocols that specify when and how these incidents should be reported and how they should be documented.
Legal teams should also have an incident response plan in place. This plan should specify what to do when security issues arise, including how to recover data, re-secure your systems, and address the situation with clients.
Promoting a culture of security
In a law firm, cybersecurity is everyone’s responsibility, not just the IT team. Leadership should encourage team members to communicate openly about any cybersecurity concerns they might have and ask questions when something isn’t clear.
Leveraging technology and expertise
Having the right technology and expertise on hand helps law firms keep their data and their systems safe. Here’s what you can do to stay safe and secure.
Managed Security Service Providers (MSSPs)
Not all law firms have the resources to hire an in-house IT team. In this case, working with a Managed Security Service Provider (MSSP) can help.
An MSSP is a group of experts that provides flexible IT and cybersecurity support. An MSSP will work with you to develop a security strategy, implement the right technology, and monitor your systems.
MSSPs are more cost-effective than hiring an in-house IT team for many firms. They offer flexible, scalable service models that can grow with your team.
Secure legal technology
Instead of using outdated legacy platforms, law firms should invest in secure tools, such as modern legal practice management software.
These platforms are designed with legal compliance and security in mind. They give firms a secure way to manage legal documents and client communications.
When choosing legal tools to implement, it’s very important to vet each provider and make sure their cybersecurity practices align with your needs.
Security audits and assessments
Don’t neglect your cybersecurity strategy once it’s been established. Conduct security audits on a regular basis to find and address vulnerabilities. Ideally, this should be done at least once per year.
