Federal prosecutors in Boston have unsealed charges against 30 people accused of running a decade-long insider-trading network built around stolen M&A intelligence. The U.S. Attorney’s Office said the scheme generated tens of millions of dollars in illicit profits by taking confidential information from law-firm systems and trading ahead of public deal announcements.
