The SEC and the U.S. Secret Service are separately investigating hackers who may be breaching corporate email accounts to gather inside information on which they can then trade, Reuters reports. News of the investigations comes approximately seven months after cybersecurity firm FireEye Inc. released a December 1, 2014 report about a group of hackers called “FIN4.” FireEye said that FIN4 was targeting the email accounts of top executives, lawyers and others in an effort to obtain non-public information about merger and acquisition deals and major market-moving announcements.
