Manhattan federal prosecutors have charged three Chinese citizens with trading on information they hacked from top merger-advising law firms in New York. The three men allegedly targeted at least seven firms, and made more than $4 million buying shares of companies in deals that were underway, then selling the stock after the mergers were announced and the stocks jumped, according to an indictment unsealed this week. The men managed to steal the emails of lawyers working on mergers from at least two of the targeted firms. You can read more about the alleged hacking at The New York Times.
