A wave of AI-driven voice phishing attacks, known as vishing, has targeted major hedge funds including Point72, Citadel, and Two Sigma. The attackers used AI-generated voices to impersonate executives and manipulate employees into granting access to sensitive systems. Point72 confirmed it was attacked but reported no client data was compromised. Two Sigma successfully thwarted the attack without any data loss. The incidents reflect a growing trend where AI tools enable cybercriminals to scale their operations significantly, allowing them to target thousands of organizations simultaneously. Cybersecurity experts warn that the cost of executing such attacks has decreased, making them more accessible to less experienced hackers. The Financial Industry Regulatory Authority (FINRA) has been alerted about the breaches and has initiated a response. The overall impact on the hedge funds remains under review as investigations continue.

Key Points: • Major hedge funds including Point72, Citadel, and Two Sigma were targeted in vishing attacks. • AI technology was used to clone voices, tricking employees into revealing sensitive information. • No successful breaches have been reported, but the incidents highlight a significant increase in cyber threats.
