The SEC are out hunting hackers who are propagating a new method of unlawful insider trading - hacking into corporate email accounts! Once inside the hackers search for confidential information on corporate M&A activity and then actively trade on it.
Since mid-2013, FIN4 has tried to hack into email accounts at more than 100 companies, looking for confidential information on mergers and other market-moving events. The targets include more than 60 listed companies in biotechnology and other healthcare-related fields, such as medical instruments, hospital equipment and drugs, according to the FireEye report.
