What are “wrench attacks”?
In cryptocurrency security, a “wrench attack” refers to the use of physical force, coercion, or intimidation to compel a victim to transfer funds or reveal private keys or seed phrases. Unlike on-chain exploits or software vulnerabilities, these incidents bypass technical safeguards by targeting individuals directly.
Why it matters
The rise in physical coercion underscores the evolving nature of crypto-related crime, where attackers increasingly seek to circumvent digital security by exploiting human vulnerabilities. The trend highlights the need for broader security practices that consider both online and real-world risks, particularly as self-custody and high-value digital asset holdings become more common.
Context
CertiK is a blockchain security auditor known for tracking exploits, scams, and operational risks across the crypto sector. Its latest findings indicate that physical threats against wallet holders grew materially from 2024 to 2025, contributing to the overall loss landscape facing investors and users.
