In one of 2025’s largest cryptocurrency thefts, approximately 3,520 BTC (valued at around $330.7 million) was stolen from a U.S.-based holder—not through a blockchain vulnerability, but via a highly sophisticated social engineering attack.
The attackers impersonated a trusted service provider, slowly building the victim’s trust over time. Once confidence was established, they manipulated the individual into revealing sensitive wallet information, most likely the seed phrase.
This theft was not the result of a technical flaw, but rather human error.
To cover their tracks, the stolen funds were rapidly dispersed across 50+ wallets and laundered through over 20 cryptocurrency exchanges, making any recovery efforts extremely difficult.
