Massive Insider Trading Allegations Rock Leading US Law Firms
Federal prosecutors in Massachusetts have unveiled one of the largest insider trading crackdowns in recent years, charging 30 individuals in a sprawling global scheme that allegedly generated tens of millions of dollars in illegal profits through the misuse of confidential merger and acquisition information. The charges were announced by the U.S. Attorney’s Office for the District of Massachusetts and involve corporate attorneys, financial professionals, traders, and intermediaries accused of exploiting privileged information stolen from elite law firms advising major corporations on sensitive business deals.
According to prosecutors, the insider trading operation lasted for nearly a decade and centered on confidential nonpublic information tied to approximately 30 mergers and acquisitions involving publicly traded companies. Authorities allege the defendants used access to internal law firm systems and confidential deal documents to trade stocks before major corporate announcements became public, enabling them to secure massive illicit gains.
The Justice Department identified Yale Law School-educated attorney Nicolo Nourafchan as a central figure in the operation. Prosecutors allege Nourafchan worked at prestigious law firms including Sidley Austin, Latham & Watkins, and Goodwin Procter between 2013 and 2023, where he allegedly accessed confidential merger information and shared it with co-conspirators.
Prosecutors claim Nourafchan collaborated closely with New York attorney Robert Yadgarov to orchestrate the scheme. The pair allegedly recruited additional lawyers, traders, and financial contacts who either supplied inside information or executed trades using the confidential knowledge. Authorities say participants were often paid substantial cash kickbacks in exchange for providing merger details before public announcements.
The indictment alleges the defendants exploited sensitive information involving major corporate transactions, including Amazon’s proposed acquisition of iRobot in 2022. Prosecutors said Nourafchan accessed confidential files related to the deal while employed at Goodwin Procter, which represented iRobot during the negotiations. Although the merger was later abandoned amid antitrust scrutiny, authorities allege traders still profited from advance knowledge of the transaction.
Federal officials emphasized that the case represents a major abuse of legal and professional trust. U.S. Attorney Leah Foley stated that the defendants allegedly violated both securities laws and the ethical obligations associated with privileged legal access. Prosecutors described the law firms involved as victims whose confidential client data was misused for personal enrichment.
Nineteen defendants were arrested across several states including California, Florida, New York, and New Jersey. Two suspects located in Russia and Israel are considered fugitives. Several others had already secretly pleaded guilty during the course of the investigation, including attorney Gabriel Gershowitz, who previously worked at firms including Weil Gotshal & Manges, DLA Piper, and Willkie Farr & Gallagher.
The defendants face charges including conspiracy to commit securities fraud, securities fraud, and money laundering conspiracy. If convicted, many could face significant prison time, financial penalties, and permanent professional consequences, particularly the attorneys accused of breaching client confidentiality obligations.
The case also highlights growing concerns within the legal and financial industries regarding cybersecurity, insider threats, and confidential data protection. Law firms involved in high-value mergers routinely possess market-moving information before public disclosure, making them prime targets for insider trading schemes. Federal authorities said the investigation remains ongoing and additional charges could still emerge.
The first indictment charges the following 16 defendants with two counts of conspiracy to commit securities fraud, two counts of securities fraud and one count of money laundering conspiracy:
- Pedram Fejal
- Brian Fensterszaub
- Mark Fensterszaub
- Simon Fensterszaub
