Top Highlights Synnovis experienced a ransomware attack in June 2024, resulting in the theft of patients’ personal data, including NHS numbers, names, and dates of birth. The breach was linked to the Qilin ransomware gang, which attacked multiple UK NHS hospitals, causing cancellations, blood shortages, and postponed procedures. Synnovis did not pay the ransom, and the stolen data was unstructured and fragmented, complicating the investigation and data recovery process. Affected NHS organizations are responsible for notifying patients, with Synnovis supporting affected entities, and the company completing notifications by November 2025. Problem Explained In June 2024, Synnovis, a prominent UK pathology…

Top Highlights In January, Microsoft obtained a court order to seize a website used by foreign threat actors distributing AI safety guardrail bypass tools, exploiting exposed customer credentials. The US Justice Department, in August, coordinated with international law enforcement to dismantle four servers and nine domains linked to the BlackSuit (Royal) Ransomware group. Despite takedown efforts, threat actors continue to be resilient; for example, Trickbot malware, targeted in a 2020 coordinated takedown involving Microsoft and others, remains active for remote access. These actions showcase ongoing efforts and persistent challenges in combating cybercrime, highlighting the need for continuous vigilance and international…
