The U.S. Securities and Exchange Commission (SEC), the country's top markets regulator, said on Wednesday hackers may have illegally profited by trading using insider information stolen from its corporate disclosure database.

The regulator said the incident took place in 2016 but that it had only detected the breach of its EDGAR system last month and that it was investigating the matter.
