Hackers launched a wave of sophisticated attacks on some of Wall Street’s biggest hedge funds and private equity firms this week, according to people familiar with the matter, marking one of the boldest attempts yet to break into the systems that manage trillions of dollars in client money.
This Wall Street cyberattack wave did not rely on malware or code. Instead, attackers picked up the phone. Sources say cybercriminals called employees directly, posing as trusted contacts in an attempt to trick staff into handing over login credentials or granting remote access to internal systems.
Point72 Confirms It Was Targeted
Point72 Asset Management, the hedge fund led by billionaire Steve Cohen, told investors on Wednesday that hackers had attempted to breach its systems. The firm said no customer information was stolen in the attempt and declined further public comment.
Point72 was not alone. Two Sigma Investments and Citadel, two of the largest quantitative hedge funds in the world, were also targeted by the same wave of attempted intrusions, according to the sources. Both firms declined to comment, and Two Sigma did not respond to requests for comment.
The Phone Call Scam Behind the Attack
Security researchers call this tactic social engineering, and it remains one of the most effective tools in a hacker’s arsenal simply because it targets people, not code. Rather than searching for a software flaw, attackers exploit trust, urgency and confusion to talk their way past a company’s defenses.
The technique has become the signature move of Scattered Spider, a loose knit group of young, English speaking hackers that has racked up a long list of corporate victims in recent years, from casinos to airlines to major retailers. Their playbook is simple and brutally effective: call the help desk, sound convincing, and ask for a password reset.
Attempts by hackers to break into major financial institutions are routine, cybersecurity experts say, but the scale and coordination of this latest wave stands out.
AI Is Making Hackers More Dangerous
The Wall Street cyberattack lands at a moment when companies worldwide are already battling a surge in AI powered cyberattacks and ransomware. Criminal groups are increasingly using artificial intelligence to write more convincing phishing scripts, clone voices and speed up reconnaissance on potential targets, making old fashioned scams like phone based social engineering even harder to spot.
Earlier this year the White House announced a new working group bringing together AI developers and operators of critical infrastructure. The goal is to share threat intelligence faster and coordinate a unified response as attacks grow more sophisticated.

Why the Wall Street Cyberattack Targeted Hedge Funds
Hedge funds and private equity firms sit on enormous pools of sensitive data, from trading strategies to investor identities to bank details, all of it valuable on the black market. A single successful breach can expose client funds, trigger regulatory scrutiny and shake investor confidence overnight.
This is not the first time a major financial name has faced a corporate security scare this year. Our earlier report on TSMC’s trade secret leak investigation showed how even the most guarded companies remain exposed to insider and external threats alike. Markets have otherwise been in a bullish mood lately, with Wall Street closing in on fresh record highs just this week, underscoring how much money is riding on these firms staying secure.
