DC's Security Cameras were Hacked Before Inauguration

The last three to four weeks have been filled with all sorts of news. Among all the information I had read, I evidently missed this story about how the security cameras in Washington, D.C. were hacked right before the presidential inauguration using ransomware. 

See this CBS News story, Days before inauguration, hackers breached D.C. traffic and security cameras The Secret Service was/is involved, not just because of the mission of protecting the president, but also because they have a cybersecurity mission for the federal government.
