A serious physical security incident has been reported involving venture capitalist Lachy Groom, where an armed perpetrator posing as a delivery driver gained entry to his residence. The attacker reportedly held the victim captive for 90 minutes, forcing the transfer of approximately $11 million in Ethereum from a self-custody wallet. This incident has ignited urgent discussions among traders and high-net-worth individuals regarding the risks associated with self-custody and personal operational security (OpSec). While the immutable nature of blockchain makes funds secure from digital hacks, the 'physical attack vector' remains a critical vulnerability for known crypto holders. Security experts in the industry are renewing calls for the use of multi-signature setups and institutional custody solutions that prevent immediate large-scale transfers under duress. The event serves as a stark reminder of the real-world dangers facing public figures in the cryptocurrency space.
