CASE STUDIES

Cyber InvestigationNation-State Intrusion into U.S. Law Firm

A large U.S. law firm representing multinational corporations in sensitive regulatory and cross-border disputes identified indicators of a sophisticated network intrusion affecting multiple practice groups. The firm’s client base included entities engaged in trade negotiations, sanctions-sensitive transactions, and high-stakes litigation.

GDR was retained under counsel to assess whether the intrusion reflected conventional criminal ransomware activity or a targeted nation-state intelligence operation. The engagement required advanced log reconstruction, endpoint forensic analysis, and review of lateral movement across segmented practice group environments.

The investigation identified infrastructure consistent with previously attributed state-sponsored threat actors, including command-and-control patterns and exfiltration methodologies aligned with geopolitical intelligence collection rather than financial extortion. Particular attention was given to the targeting of client-related regulatory strategy documents and privileged communications.

GDR worked alongside internal IT leadership to contain exposure, preserve evidentiary integrity, and implement segmentation reinforcement without disrupting active client matters.

The structured findings enabled the firm to brief affected clients with precision, coordinate with federal authorities where appropriate, and reinforce cyber governance architecture against future state-sponsored intrusion attempts.
