(Reuters) The top U.S. markets regulator said on Wednesday that hackers accessed its corporate disclosure database and may have illegally profited by trading on the insider information stolen.
The Securities and Exchange Commission (SEC) said the hack occurred in 2016 but that it had only discovered last month that the cyber criminals may have used the information to make illicit trades.
The hackers exploited a software glitch in the test filing component of the system to gain access to non-public information, the agency said.
