Constrained

Case description

In 2023, Rocelo Lopes—a Brazilian Bitcoin entrepreneur—received a call from captors who had kidnapped his wife after she dropped their daughter at school in Florianópolis. The kidnappers demanded cryptocurrency ransom and specifically instructed Lopes to pay in privacy-focused coins rather than Bitcoin, demonstrating sophisticated knowledge of blockchain traceability. Lopes's wife was held captive in São Paulo. The case was documented by NBC News as part of a broader investigation into rising wrench attacks globally.
