Data Breaches Digest: Ransomware Victims

Editor's Message

Welcome to DBD. Cybercrime made global headlines in 2025. Attacks on well-known brands and organizations have raised public awareness of the severity, frequency and impact of cyber attacks. Ransomware attacks are at their highest ever recorded, and 2026 has the potential to be even worse, as cyber criminals continue to extort their victims, with little chance of being brought to justice. On a lighter note, I'd like to take this opportunity to wish you all a very Merry Christmas and all the best for the New Year. Thanks again for all your support. Stay safe. :)

“Data Breaches Digest and its PRiSM portal provide Dentons Global Security Team with valuable insights into the ransomware landscape, from the latest incidents to trends over time, as well as the ability to customize visual analytics.
