Hackers have increasingly turned to AI voice cloning to execute sophisticated cyberattacks on major Wall Street firms, including Point72, Citadel, and Millennium.12
The attacks, characterized as vishing (voice phishing), involved cybercriminals impersonating voices to deceive employees into revealing sensitive information.5
Point72 confirmed the attack on Wednesday, stating that no client information was stolen during the incident, although they are still reviewing the situation.
Two Sigma, managing $75 billion in assets, reported that it successfully blocked the hacking attempt, with a spokesperson stating, “Our security team responded quickly to an attempted vishing campaign targeting Two Sigma and other investment managers, and we have no indication of any impact to our data or our systems.”3
The Financial Industry Regulatory Authority (FINRA) has been in contact with member firms regarding these breaches, emphasizing the need for enhanced cybersecurity measures.4
Experts warn that the commoditization of AI technology has made it easier for hackers to execute attacks at scale, with one expert stating, “Everybody will have to seriously level up. Otherwise they are going to be in big trouble.”
The White House has also initiated a working group to unite AI developers and critical infrastructure operators to share threat intelligence and bolster defenses against such cyber threats.
“Two Sigma, which manages $75 billion in assets, told Bloomberg it successfully blocked the attempt, while Point72 informed investors no client information was stolen. FINRA has been in contact with member firms about the breaches, and the White House announced a working group to coordinate cyber defenses.”
