Crypto holders in California are increasingly targeted in violent "wrench attacks," where criminals use physical force to steal digital assets. Posing as delivery drivers, attackers have struck in San Francisco, Sunnyvale, San Jose, and Los Angeles, exploiting the irreversible nature of crypto transactions. In one San Francisco incident, a victim lost $13 million in Bitcoin and Ethereum after attackers disguised as pizza delivery drivers forced him to surrender wallet access. Authorities report that criminals may be using food delivery platforms to identify targets, with incidents involving fake deliveries becoming more common. In Sunnyvale, a suspect was apprehended after attempting a fake DoorDash delivery, while in Los Angeles, attackers threatened a victim with physical harm to access his cryptocurrency. Arrests have been made, but investigators suspect a larger network is orchestrating these attacks. A 2025 CertiK report highlights that wrench attacks are a growing global issue, with Europe accounting for over 40% of incidents. Financial losses from these attacks have surged, emphasizing the need for crypto holders to prioritize both physical and digital security measures.
