Hackers launched a coordinated wave of attacks against some of Wall Street's largest hedge funds in recent days, using AI to mimic employees' voices and trick staff into granting system access, according to a Bloomberg report published Wednesday.
Inside the Target List Two Sigma Investments confirmed it was targeted in an attempted vishing (voice phishing) campaign.
"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," Two Sigma said in a statement, per Bloomberg.
Ken Griffin’s Citadel and Steve Cohen’s Point72 Asset Management were also targeted, though spokespeople for both firms declined to say whether hackers actually breached their systems.
Several unnamed private equity firms faced similar attempts, per Bloomberg.
