Blockchain security firm CertiK has reported a significant increase in 'wrench attacks' targeting cryptocurrency holders, with 34 confirmed incidents in the first four months of 2026. This marks a 41% rise compared to the previous year, resulting in approximately $101 million in losses. If the trend continues, annual losses could reach several hundred million dollars. The report highlights that 82% of these attacks occurred in Europe, with France alone accounting for 24 incidents. Attackers are increasingly using data-driven methods to select targets, purchasing personal information such as names, addresses, and financial details. They are also targeting victims' families to exert pressure. Common tactics include impersonating delivery personnel, police officers, and conducting fake OTC transactions.
