We have learned in recent days of what appears to be a massive cybersecurity breach affecting potentially thousands of victims, including U.S. companies and federal government entities. There’s a lot we don’t yet know, but what we do know is a matter of great concern. I have instructed my team to learn as much as we can about this breach, and Vice President-elect Harris and I are grateful to the career public servants who have briefed our team on their findings, and who are working around-the-clock to respond to this attack.
I want to be clear: my administration will make cybersecurity a top priority at every level of government — and we will make dealing with this breach a top priority from the moment we take office. We will elevate cybersecurity as an imperative across the government, further strengthen partnerships with the private sector, and expand our investment in the infrastructure and people we need to defend against malicious cyber attacks. But a good defense isn’t enough; we need to disrupt and deter our adversaries from undertaking significant cyber attacks in the first place. We will do that by, among other things, imposing substantial costs on those responsible for such malicious attacks, including in coordination with our allies and partners. Our adversaries should know that, as President, I will not stand idly by in the face of cyber assaults on our nation.
