In June 2022, Clark Patterson Lee experienced a ransomware attack that resulted in the unauthorized encryption of network files over a two‑day period. The intrusion prompted the firm to engage cybersecurity experts to investigate the scope of the breach. Following an internal review, the firm identified individuals whose personal information may have been accessed and issued breach notification letters to them. The compromised data likely included Social Security numbers or financial details, consistent with regulatory reporting standards for such incidents. Although the firm confirmed that files were encrypted, it did not publicly disclose whether the attackers exfiltrated data or demanded a ransom payment. The incident highlights the ongoing ransomware threat faced by professional services firms that handle sensitive client information.
