Ukraine Says Russia is Behind Cyberattack

President Joe Biden has been briefed on a cyber attack against Ukraine. White House Press Secretary Jen Psaki said, adding that "personal data was not accessed" and Ukrainians were able to get their "systems up and running." The Biden administration believes Russian actors are preparing potential sabotage operations against their own forces and fabricating provocations in social media to justify an invasion into Ukraine, according to a U.S. official.
