French authorities freed Ledger co-founder David Balland after a cryptocurrency ransom kidnapping in January 2025. Crypto-related violence is on the rise, with wrench attacks involving physical coercion to access funds becoming more prevalent. Wrench attacks seek to bypass cryptography by exploiting personal leverage over victims.

Wrench attacks are physical crimes that leverage threats or violence to compel crypto holders to reveal access credentials or authorize transfers. These attacks aim to obtain cryptocurrency by targeting individuals rather than exploiting digital security measures. The term “wrench attack” originates from a comic highlighting the vulnerability of strong encryption to physical coercion.

Reported wrench attacks have increased over time, correlating with fluctuations in total crypto market capitalization. However, underreporting and fear of revictimization may skew data analysis. Wrench attacks are driven by fast payouts, rising wealth concentrations, easy targeting, and data leaks linking online identities to offline risks.

Wrench attacks target individuals with significant crypto holdings, including founders, public figures, and traders. Western Europe and parts of the Asia-Pacific region have seen a surge in reported incidents. To lower risk, individuals should reduce visibility, maintain separate spending and storage accounts, and be cautious of support impersonation attempts.

In the event of a wrench attack, prioritize physical safety over protecting assets. Stay vigilant, reduce visibility, and be mindful of personal data exposure to mitigate risk. Wrench attacks highlight the intersection of digital wealth and physical security, emphasizing the need for enhanced personal security measures in the crypto industry.
