Bitcoin security firm Casa has deployed four new protective features targeting social engineering, the attack method behind the majority of crypto theft in 2025. The release comes as FBI data shows crypto fraud losses rose 22% year over year to exceed $11 billion. Social engineering attacks manipulate victims psychologically rather than exploiting technical vulnerabilities, making them particularly difficult to defend against with conventional security tools. Casa's new features are immediately available to existing customers. The move reflects growing industry concern over escalating fraud tactics aimed at Bitcoin holders, with providers increasingly shifting focus from hardware and cryptographic protections toward safeguards that address human vulnerabilities in the custody and transaction process.
