Blockchain security firm CertiK projects that 2026 will close with 130 crypto wrench attacks and hundreds of millions in losses, as physical violence against digital asset holders continues to accelerate. The projection comes after a 41% year-over-year jump in verified incidents between January and April 2026, with 34 cases recorded. These attacks involve physical coercion—often through threats or actual violence—to force victims to transfer their crypto assets, targeting both individuals and exchanges. The rising trend of wrench attacks underscores a shift in crypto theft from digital exploits to physical intimidation. CertiK's data shows that these attacks are becoming more frequent and sophisticated, with attackers targeting high-profile holders, DeFi participants, and even exchange employees. The firm attributes the increase to the growing value of crypto holdings and the perception that victims may be easier to coerce than to hack. For wallet and key holders, this highlights the need for physical security measures alongside digital protections. Best practices include avoiding public disclosure of holdings, using multi-signature wallets with time locks, and storing private keys in secure, off-site locations. Additionally, employing anonymity tools and transaction monitoring can reduce risk. The trend reinforces the importance of holistic security strategies that account for physical threats, not just cyber vulnerabilities.
