U.S. authorities have arrested and charged three individuals suspected of conducting 'wrench attacks' targeting cryptocurrency holders. The group allegedly infiltrated delivery accounts such as DoorDash and Uber Eats to track victims' routines, posing as delivery personnel to execute armed robberies. In a notable incident last November, a San Francisco victim was bound and assaulted at home, losing approximately $10 million in Bitcoin and $3 million in Ethereum. Police suspect the group is linked to similar cases in San Jose, Sunnyvale, and Los Angeles, potentially involving higher-level organizers.
