Time to Review Cybersecurity

As the year is winding down for law firms, it would be a good time to review their cybersecurity protocols. A major threat is ransomware attacks. 

In 2022, LockBit was the most deployed ransomware variant worldwide and continued to be prolific in 2023. Since January 2020, LockBit affiliates have attacked organizations of varying sizes across various critical infrastructure sectors, including financial services, food and agriculture, education, energy, government and emergency services, healthcare, manufacturing, and transportation.

Law firms are prime targets for cyberattacks due to the sensitive nature of client information they handle. Understanding the threat landscape and implementing comprehensive cybersecurity measures is crucial. Here's what law firms should know about cybersecurity and how to prevent actors like LockBit.

A data breach at the Orrick, Herrington & Sutcliffe law firm resulted in a class action lawsuit. The hackers reportedly accessed data collected by the firm involving 460,000 people. A settlement was recently reported.

Threats and vulnerabilities:

  • Data breaches: Hackers steal sensitive client data like Social Security numbers, financial records, or legal documents.
  • Ransomware attacks: Encryption of computer systems and data with demands for large payments to regain access. LockBit is a notorious ransomware group known for its aggressive tactics and large ransom demands.
  • Phishing: Deceptive emails or messages tricked employees into giving away login credentials or downloading malware.
  • Insider threats: Disgruntled employees or malicious actors with access to systems can cause significant damage.

Prevention strategies:

  • Implement a layered security approach: Strong firewalls, intrusion detection and prevention systems, endpoint protection, and data encryption.
  • Train employees on cybersecurity awareness: Regularly educate staff on identifying phishing attempts, protecting passwords, and safe browsing practices.
  • Conduct regular security assessments: Vulnerability scans and penetration testing can identify weaknesses in your systems before attackers exploit them.
  • Use multi-factor authentication (MFA): Require additional verification besides passwords for accessing sensitive systems.
  • Back up data regularly: Maintain secure backups of critical data to restore it in case of a cyberattack.
  • Have an incident response plan: Outline steps to take in a cyberattack to minimize damage and restore operations quickly.
  • Comply with data protection regulations: Understand and comply with regulations like HIPAA or GDPR for safeguarding sensitive data.

Specifically for LockBit:

  • LockBit encrypts data quickly and demands high ransoms. Be prepared to negotiate or consider alternative means of recovery like backups.
  • LockBit operates through affiliated "cartels" with varying tactics. Stay informed about their current strategies and potential vulnerabilities.
  • Invest in advanced endpoint protection. Look for solutions that detect and block ransomware at the earliest stages.
  • Prepare for offline attacks. LockBit has targeted backups before, so ensure offline storage is secure.

By implementing these measures, law firms can significantly reduce their risk of cyberattacks and protect their valuable client data. Remember, cybersecurity is an ongoing process, not a one-time fix. Continuously educate your staff, stay updated on evolving threats, and adapt your security measures accordingly.

It's crucial to seek professional help from cybersecurity experts to assess your firm's needs and implement appropriate solutions. Don't hesitate to involve your IT team and consider consulting with legal counsel regarding data protection regulations and best practices.

Law firms can create a robust cybersecurity posture and stand stronger against threats like LockBit by taking proactive steps.
