Three Chinese individuals have been charged in a Manhattan federal court with insider trading. Prosecutors allege the three hacked into U.S. law firms and made $4 million trading on nonpublic information. The court complaint alleges that the individuals retrieved emails of law firm partners who were working on merger and acquisitions on companies such as Intermune, which was acquired by Roche in August 2014. The alleged hackers also followed Intel's (INTC) - Get Report combination with Altera. Reports say one of the traders was taken into custody in Hong Kong.
