AI voice phishing wave targets hedge funds and tries to breach others
The attackers used AI-generated voice clones to impersonate insiders, and Two Sigma said its security team stopped the intrusion attempt before any systems or data were compromised.
A wave of attempted break-ins hit major hedge funds, using AI-generated voices to impersonate colleagues and pressure staff into handing over access, Insurance Business reports. Investigators described the tactic as “vishing,” or voice phishing, where fraudsters clone the voice and speech patterns of real employees or executives to talk their way past coworkers by phone.
Point72 Asset Management said it was hit by hackers, with early indications that no client data was taken, Bloomberg reported through people familiar with the matter. The same campaign also attempted to breach systems at Millennium Management, Two Sigma Investments and Citadel, along with several private equity firms, according to Bloomberg and Reuters sources.
Two Sigma, which manages roughly $75 billion, said its security team caught the intrusion attempt before any systems or data were compromised. Millennium, Point72 and Citadel declined to comment on the record, Insurance Business added.
In parallel, JPMorgan Chase chief executive Jamie Dimon has been personally calling dozens of banks, insurers, utilities and telecoms firms to get them into an industry group aimed at staying ahead of AI-driven threats, the outlet said. Align Managed Services president Vinod Paul told Bloomberg that generative AI has made it easier to scale attacks, shrinking what used to take weeks by hand into efforts that can target far more organizations quickly.
