White House says Biden warned Putin on ransomware attacks

What they're saying: "I made it very clear to him that the United States expects when a ransomware operation coming from his soil — even though it’s not sponsored by the state — we expect him to act. And we’ve given him enough information to act on who that is,” Biden said on Friday afternoon.

• “His intent was to make clear and reiterate again that ransomware attacks by criminal groups on entities in the United States is not acceptable and that we reserve the right to take action,” White House press secretary Jen Psaki said earlier in the day.

Of note: When asked before departing Joint Base Andrews later on Friday whether it makes sense to attack servers that are used to carry out ransomware attacks, the president smiled and answered, "yes," according to the White House press pool.
