A major insider trading scheme has resulted in charges against 30 individuals, including corporate attorneys and financial professionals, according to the Massachusetts District Attorney's Office. Nineteen defendants were arrested, with two fugitives located in Russia and Israel. The FBI dismantled a large-scale, international criminal network accused of stealing and trading on confidential information from leading law firms. The defendants are accused of making significant profits from expected market movements. They allegedly stole and used confidential information on nearly 30 merger and acquisition deals from US law firms. A 2022 text exchange between defendants Gavryel Silverstein and Simon Fensterszaub used coded language referencing a deal involving iRobot. Both Silverstein and Fensterszaub face multiple charges, including conspiracy to commit securities fraud and money laundering. Authorities emphasize the importance of a level playing field for all investors. The trading on unannounced financial news violated securities laws and breached ethical duties. The charges are part of an ongoing effort to ensure fairness in the financial markets.
