Two groups account for a third of UK ransomware attacks
Two ransomware groups now account for a third of UK attacks. AI is making it easier to scale, harder to predict.

Why it matters
Ransomware attacks are shifting geographically (Europe rising, US declining) and concentrating among fewer, more capable groups. The operational risk for enterprise defenders is that AI-assisted reconnaissance and payload customization are lowering the barrier to scale — meaning more targets face threats from better-resourced, higher-velocity actors.
