Word of the Week: “Phishing” 🎣 in the Legal Profession - What Every Lawyer Needs to Know in 2025 🛡️

Lawyers Battle phishing on a daily basis.

Phishing is one of the most persistent and dangerous cyber threats facing law firms today. Phishing is a form of computer and internet fraud in which criminals use fake emails, websites, or messages to trick recipients into revealing sensitive information such as passwords, bank details, or client data. For lawyers and legal professionals, the stakes are especially high: law firms hold vast amounts of confidential client information, making them prime targets for cybercriminals. The American Bar Association (ABA) Model Rules for Professional Conduct, particularly Rule 1.6 (Confidentiality of Information) and Rule 1.1 (Competence), require lawyers to protect client data and maintain competence in technology relevant to their practice.

How Phishing Targets Law Firms

Phishing attacks against law firms have become more sophisticated in 2025. Criminals now use generative AI to craft emails that closely mimic real communications from clients, colleagues, or even senior partners. These messages often create a sense of urgency, pressuring recipients to act quickly—such as transferring funds, sharing login credentials, or downloading malicious attachments. Business Email Compromise (BEC) scams are particularly damaging, as attackers impersonate managing partners or clients to divert wire transfers or request sensitive documents.

Impersonation: The Hidden Dangers in Your Inbox

Attackers often use email spoofing to manipulate the display name and email address, making a message appear to come from someone you trust. The display name (the name that appears in your inbox) can be set to any familiar contact, but the actual email address may be subtly altered or completely fake. For example, a scammer might use “john.smith@lawfirm.com”or “John Smith of ….” as the display name, but the underlying address could be “jjohn.smith@lawf1rm.com” or “john..john.smith@lawfirm.co@lawfirm.co.” These changes are often just a single character off, designed to trick you into replying or clicking a malicious link.

Lawyers should always examine the full email address, not just the display name, before responding or acting on any request. On many smartphones and email clients, only the display name is shown by default, so you may need to click or tap to reveal the actual sender’s email address. If the message requests sensitive information, money transfers, or urgent action, verify the request through a separate communication channel, such as a phone call using a known number—not one provided in the suspicious email. This vigilance aligns with ABA Model Rule 1.1, which requires lawyers to maintain competence, including understanding risks associated with technology.

Recent Phishing Incidents Involving Lawyers

Phishing Email Threatens Law Firm Cybersecurity Defense

What Lawyers Should Watch For

  • Impersonation: Always check the sender’s full email address, not just the display name. Watch for addresses that are off by one or more characters.

  • Urgency and Pressure: Be cautious of emails that demand immediate action, especially those involving money or confidential data.

  • Suspicious Links or Attachments: Hover over links to check their true destination, and never open unexpected attachments.

  • Unusual Requests: Be wary of requests outside normal procedures, such as buying gift cards or changing payment instructions.

Prevention and Best Practices

  • Employee Training: Regular cybersecurity awareness training is crucial. Staff should be able to recognize phishing attempts and know how to report them. This supports ABA Model Rule 5.3 (Responsibilities Regarding Nonlawyer Assistance).

  • Multi-Factor Authentication (MFA): MFA adds an extra layer of security, making it harder for attackers to access accounts even if credentials are compromised.

  • Incident Response Plan: Every law firm should have a clear plan for responding to phishing incidents, including communication protocols and legal obligations for breach notification.

  • Client Education: Educate clients about phishing risks and encourage them to verify any unusual requests that appear to come from your firm.

Professional Responsibility and Phishing

lawyers need to be proactive Against Cybersecurity Threats in 2025!

The ABA Model Rules make clear that lawyers must take reasonable steps to prevent unauthorized access to client information (Rule 1.6(c)). Lawyers must also keep abreast of changes in technology and its associated risks (Rule 1.1, Comment 8). Failing to implement basic cybersecurity measures, such as phishing awareness and email verification, may expose lawyers to disciplinary action and civil liability.

Final Thoughts

Phishing is not just an IT problem—it’s a business risk that can compromise client trust, cause financial loss, and result in legal liability. By staying vigilant, investing in training, and adopting robust security measures, lawyers can protect themselves, their clients, and their reputations in an increasingly digital world. Compliance with the ABA Model Rules is not optional—it's essential for ethical and effective law practice.

BOLO: LexisNexis Data Breach: What Legal Professionals Need to Know Now—and Why All Lexis Products Deserve Scrutiny!

LAWYERS NEED TO BE BOTH TECH-SAVVY AND Cyber-SavvY!

On December 25, 2024, LexisNexis Risk Solutions (LNRS)—a major data broker and subsidiary of LexisNexissuffered a significant data breach that exposed the personal information of over 364,000 individuals. This incident, which went undetected until April 2025, highlights urgent concerns for legal professionals who rely on LexisNexis and its related products for research, analytics, and client management.

What Happened in the LexisNexis Breach?

Attackers accessed sensitive data through a third-party software development platform (GitHub), not LexisNexis’s internal systems. The compromised information includes names, contact details, Social Security numbers, driver’s license numbers, and dates of birth. Although LexisNexis asserts that no financial or credit card data was involved and that its main systems remain secure, the breach raises red flags about the security of data handled across all Lexis-branded platforms.

Why Should You Worry About Other Lexis Products?

LexisNexis Risk Solutions is just one division under the LexisNexis and RELX umbrella, which offers a suite of legal, analytics, and data products widely used by law firms, courts, and corporate legal departments. The breach demonstrates that vulnerabilities may not be limited to one product or platform; third-party integrations, development tools, and shared infrastructure can all present risks. If you use LexisNexis for legal research, client intake, or case management, your clients’ confidential data could be at risk—even if the breach did not directly affect your specific product.

Ethical Implications: ABA Model Rules of Professional Conduct

ALL LawyerS NEED TO BE PREPARED TO FighT Data LeakS!

The American Bar Association’s Model Rules of Professional Conduct require lawyers to safeguard client information and maintain competence in technology. Rule 1.6(c) mandates that attorneys “make reasonable efforts to prevent the inadvertent or unauthorized disclosure of, or unauthorized access to, information relating to the representation of a client.” Rule 1.1 further obligates lawyers to keep abreast of changes in law and its practice, including the benefits and risks associated with relevant technology.

In light of the LexisNexis breach, lawyers must:

  • Assess the security of all third-party vendors, including legal research and data analytics providers.

  • Promptly notify clients if their data may have been compromised, as required by ethical and sometimes statutory obligations.

  • Implement additional safeguards, such as multi-factor authentication and regular vendor risk assessments.

  • Stay informed about ongoing investigations and legal actions stemming from the breach.

What Should Legal Professionals Do Next?

  • Review your firm’s use of LexisNexis and related products.

  • Ask vendors for updated security protocols and breach response plans.

  • Consider offering affected clients identity protection services.

  • Update internal policies to reflect heightened risks associated with third-party platforms.

The Bottom Line

The LexisNexis breach is a wake-up call for the legal profession. Even if your primary Lexis product was not directly affected, the interconnected nature of modern legal technology means your clients’ data could still be at risk. Proactive risk management and ethical vigilance are now more critical than ever.
