A decade-long scheme allegedly saw lawyers at top Wall Street firms, including Goodwin Procter and Wachtell Lipton, systematically leak confidential M&A data to a global network of traders, resulting in tens of millions in illicit gains.

Federal prosecutors have charged 30 individuals in a brazen, decade-long insider trading scheme, alleging that lawyers at several elite U.S. law firms systematically stole and sold confidential information on dozens of pending corporate mergers.
"We are deeply disappointed that a former employee is alleged to have violated the trust placed in him and misused confidential information as part of a broader criminal scheme," Goodwin Procter said in a statement, one of several firms caught up in the scandal.
The scheme, allegedly orchestrated by Yale Law graduate Nicolo Nourafchan, involved tips on nearly 30 deals, including Amazon.com Inc.’s planned acquisition of iRobot Corp. and Burger King’s 2014 takeover of Tim Hortons. The U.S. Securities and Exchange Commission has filed parallel civil charges against 21 of the individuals, alleging the ring made tens of millions of dollars in illicit profits.
The scandal exposes significant vulnerabilities in the data security of top-tier law firms that are custodians of market-moving information, raising questions about compliance protocols and the potential for wider regulatory scrutiny of the multi-trillion dollar M&A advisory industry.
According to the indictment, Nourafchan, a lawyer who job-hopped between prestigious firms such as Sidley Austin, Latham & Watkins, and Goodwin Procter, was the scheme's central figure. He is accused of mining his employers' computer systems for information on pending deals, even accessing documents for matters he was not assigned to. Prosecutors say he viewed files in "preview or read-only mode" to minimize detection.
The stolen information was then allegedly passed to a college classmate, Robert Yadgarov, who funneled the tips to a wide network of traders. This network reportedly included another lawyer, Gabriel Gershowitz from Weil Gotshal, and Avi Sutton, who worked at Wachtell Lipton and later became general counsel at investment bank LionTree. The web of contacts was extensive, involving friends, relatives, and even a hair stylist, with traders located in Florida, New York, Russia, and Israel.
The alleged profits were substantial. In the iRobot deal alone, the group is said to have netted more than $1.7 million. Prosecutors detailed how Nourafchan’s brother, Lorenzo, tipped off his hair stylist, who then passed the information to a friend. After the deal was announced, the friend texted the stylist: "You were right."
For years, the scheme operated without detection, with participants allegedly using coded language in text messages, referring to trading connections as a "construction crew" and a pending deal as a "surgery" for a "rabbi." The unraveling began when authorities, initially suspecting foreign hackers, traced a pattern of well-timed trades back to an inside source. An undercover agent eventually contacted one of the participants in early 2024, leading to the collapse of the decade-long operation.
The fallout has been swift, with the implicated law firms issuing statements distancing themselves from the accused individuals and stressing that the firms themselves were victims. Wachtell and Latham noted the individuals had not been with their firms for several years, while Weil stated the alleged conduct was "extremely serious." The case serves as a stark reminder that even with robust compliance policies, the human element remains a critical vulnerability in safeguarding sensitive, market-moving information.
