Ransomware with PC and locks arround

Introduction

In early June 2024, a major ransomware attack targeted several NHS hospitals in London. This cyber attack, orchestrated by the Russian cybercriminal group Qilin, severely disrupted medical services. It led to the cancellation of critical operations and tests. This article delves into the details of the attack, the group behind it, and the broader implications for cybersecurity in healthcare.

What is Qilin?

Qilin is a notorious Russian cybercrime gang operating a ransomware-as-a-service model. Known for their sophisticated attacks, Qilin primarily targets large organizations and critical infrastructure, demanding hefty ransoms in exchange for decrypting compromised data​ (The Independent)​​.
