In an unprecedented move by a Chinese National Hacking Group, called Hafnium, hundreds of thousands of Exchange servers have been compromised, with over 30,000 accounts hacked this week. Leo says it's worse than that Russian Solar Winds attack. The hack takes advantage of a quartette of "zero-day exploits" that take advantage of bugs in Microsoft's Exchange email servers. Microsoft has put out an emergency update to plug the holes, and users are advised to install the fix immediately.
Reacting to the recent SolarWinds hack by Russia, the US has created a new Cybersecurity for Emerging Technologies agency. Leo says that it will largely focus on security and diplomacy.
