ChainCatcher reports that the latest security report from GK8 shows that cybercriminals are recruiting professional voice impersonators on underground forums to launch sophisticated "vishing" (voice phishing) attacks targeting US cryptocurrency executives. These highly customized attacks target high-value individuals with custody infrastructure and private key access, with operators earning up to $20,000 per month. Attackers use carefully collected executive personal information, deepfake technology, and voice changers to impersonate banks, crypto services, and government agencies for social engineering attacks. Tanya Bekker, Head of Security Research at GK8, warns that in the next 12-18 months, distinguishing between real and fake will become increasingly difficult, and recommends that crypto organizations implement specific protocols and training to counter voice and video social engineering tactics.
