We have tracked the leak sites of every active extortion group since 2020. The Security Navigator 2027 maps who is behind the attacks, who gets hit – and where in Europe the gangs are moving.
Leak sites are where extortion gangs publish the victims who refuse to pay. Our security research team tracks them across every active group – and from that data show which gangs set the pace, which organizations end up on the lists and how the map of Europe is shifting.
We record victims that extortion groups publish on their leak sites, for October 2025 to September 2026. It is a partial view of cybercrime – it misses victims who pay quietly – but a useful and objective proxy for trends. The chapter also compares where victims are posted with where you would expect them, given the size of each economy.

The visible extortion economy grew rapidly, but it is not confined to one industry, one country or one organisation size.
