Former National Security Agency chief Keith Alexander warned that the United States is “not ready” to combat against a potential flurry of cyberattacks from Russia and China.

On Sunday, Alexander said hacks from the two nations are “more blatant than” any he’s ever seen throughout his “whole career.” The former NSA boss said President Joe Biden’s March 12 executive order, which was intended to bolster the country’s response to cyberattacks through coordination with the private sector, is a step in the right direction, adding that more needs to be done.
