The U.S. Securities and Exchange Commission says it found out last year that it got hacked — and we're only just now hearing about it.
The hack targeted the SEC's Edgar system, which stores and distributes more that 1.7 million corporate filings to the agency each year. In 2016, the agency found intruders entered the system using a vulnerability in its testing software.
The SEC says the hackers didn't make off with any personal information. But they did get access to information before it went public, and the agency thinks the attackers made illegal trades based on the stolen info.
