It was clear from the start that a cyber attack by suspected Russian hackers aimed at several U.S. government agencies was going to be bad. One clue: National Security Advisor Robert O’Brien cut short a trip overseas early this week to rush back to Washington to help manage the crisis.

It started with a bulletin from the U.S. Cybersecurity and Infrastructure Security Agency, known as CISA, warning that the hackers were sophisticated, patient and well-resourced, representing a “grave risk” to federal, state and local governments as well as critical infrastructure and the private sector. It didn’t take long to see how accurate the agency’s assessment was.
