Crypto "Wrench Attacks" Drive Exchanges and Executives to Ramp Up Security Spending

A wave of crypto-related kidnappings, home invasions and so-called "wrench attacks" is pushing exchanges and prominent industry figures to step up personal protection, Bloomberg reported. Coinbase disclosed in its latest proxy filing that it spent about $8.7 million in 2025 on security for CEO Brian Armstrong and related protective measures, up from roughly $6.2 million in 2024. Gemini's most recent filing shows the firm pays Winklevoss Capital Management $400,000 a month for executive protection, secure transportation and risk-advisory services covering its CEO and president, as well as their families.
