At the 2025 Litecoin Summit, Casa CTO Jameson Lopp delivered a critical warning about the rise of physical attacks targeting cryptocurrency holders. Drawing upon over a decade of security experience, Lopp outlined the increasing frequency and severity of “wrench attacks,” where criminals use coercive means to force victims into revealing private keys or sensitive access credentials. Lopp illustrated this concept using an XKCD comic, emphasizing that no matter how strong encryption is, human vulnerabilities can become the weakest link in asset security. 230 known wrench attack incidents have been recorded, while a Cambridge study revealed over 672 discussions of physical attacks on Bitcoin Talk forums alone.
