Major Hedge Funds Targeted in Wave of Attempted Cyberattacks

Hackers used vishing and AI voice mimicry to target firms overseeing trillions of dollars in assets, Bloomberg News reported.

  • On Wednesday, hackers launched a coordinated wave of attacks against major hedge funds including Two Sigma Investments, Citadel, and Point72 Asset Management, using AI-generated voice phishing to trick employees into granting system access.
  • Modern AI systems have "commoditized" hacking skills, allowing bad actors to scale operations from 50 to 1,000 targets, said Will Wilson, CEO of IT security firm Antithesis. He warned, "Everybody will have to seriously level up."
  • Attackers use technology to replicate voice, tone, and phrasing in phone calls to deceive staff. Two Sigma confirmed it thwarted an attempt, while Point72 and Citadel declined to comment on whether systems were breached.
  • The Financial Industry Regulatory Authority is coordinating industry responses through its Financial Intelligence Fusion Center, a secure portal launched in March for member firms to share fraud intelligence and threat data.
  • AI-Powered cyberattacks have surged over the past year as cheap, scalable tools make professional services firms increasingly vulnerable to deepfake-driven fraud attempts targeting trillions in daily Wall Street transactions.
