Summary

A large-scale international investment fraud network, dismantled by Dutch and Belgian police in July 2026, operated approximately 20 call centers staffed by over 700 people who posed as financial advisers and used fake cryptocurrency trading platforms to steal an estimated €100 million per month from victims worldwide. The alleged mastermind — Ehud Tenenbaum, a 46-year-old dual Israeli-Polish national known in cybercrime circles as 'The Analyzer' for his late-1990s hacking of U.S. government systems — was arrested in Poland in May 2026 and extradited to the Netherlands. Tens of thousands of victims across multiple countries are estimated, with Dutch victims alone reporting nearly €25 million in losses.
