Overview
- The National Crime Agency arrested four suspects in connection with ransomware attacks that targeted Marks & Spencer, the Co-op and Harrods.
- Marks & Spencer resumed online clothing orders on June 10, but click-and-collect and next-day delivery remain suspended as the retailer rebuilds its IT systems.
- Investigators determined that the April 17 breach exploited a sophisticated social-engineering impersonation of a third-party user and linked the hack to DragonForce and the Scattered Spider collective.
- M&S estimates the disruption cost about £300 million in lost operating profit and is pursuing insurance claims while reviewing its legacy infrastructure.
- Chair Archie Norman described the attack as "traumatic" in parliamentary testimony and called for mandatory incident reporting to strengthen national cyber defenses.
