Empty shelves, lost customers, and hundreds of millions of pounds in lost profit are just some of the outcomes that retailers have faced in the wake of recent ransomware attacks. From the Co-operative to M&S, the recent cyber attacks on UK retail giants have dominated headlines and wreaked havoc that’s been felt by customers, staff, and government officials alike.
The culprits behind it? A highly organised group of ransomware specialists, codename: DragonForce.
Join Group-IB’s Gary Ruddell and Nick Palmer as they speak with Jason Rebholz, an expert on the ransomware ecosystem, with over a decade of experience performing forensic investigations into complex cyberattacks.
In this episode, they unpack how DragonForce evolved into a ransomware cartel, franchising their malware to affiliates like Scattered Spider, whose sophisticated social engineering tactics have significantly disrupted UK retail. They explore the wide-ranging impact on both businesses and consumers, offering insights into how each can better protect themselves. Finally, they examine the role of policy and regulation in preventing future attacks and strengthening cyber resilience.
By understanding who these actors are and how they operate, you can better anticipate threats and protect yourself in an increasingly hostile digital world.

In this episode we explore the two front lines of the modern fraud economy.


In this episode we examine the implications of biometric theft, the future of digital identity in an AI driven world, and how we can rebuild trust where proving who we are online is becoming increasingly complex.
