Cyber Annual Reports

2025 was a year of complexity and unprecedented developments for our cyber team. Many incidents raised novel issues and challenging questions that we had not encountered before. Ransomware remained a dominant theme, accounting for 52% of our matters, while supply chain incidents surged, rising from 6% in 2024 to nearly 20% in 2025.

This seventh edition of our annual cyber report considers the matters the team handled in 2025, provides insight into law enforcement engagement, and assesses the impact of supply chain breaches along with the litigation and regulatory investigations that follow. Our global regulatory roundup features special content provided by Constangy Brooks Smith & Prophete LLP.
