Federal prosecutors are set to unveil charges in an international stock trading scheme that involved hacking into the Securities and Exchange Commission's EDGAR corporate filing system.

The scheme allegedly netted $4.1 million for fraudsters from the U.S., Russia and Ukraine. Using 157 corporate earnings announcements, the group was able to execute trades on material nonpublic information, according to Reuters. Some of those filings were "test filings," which corporations upload to the SEC's website.
