Governments and computer experts girded Monday for a possible worsening of the global cyberattack that has hit more than 150 countries, as Microsoft warned against stockpiling vulnerabilities like the one at the heart of the crisis. "We don't have a large number of victims right now, and we, for the most part, are not seeing significant operational impacts for those who have been victimized".
