Russia is allegedly hacking American research groups to steal information about a potential COVID-19 vaccine. China is doing the same. Presumably, U.S. spies are also keeping an eye on Chinese research facilities that are working on solving the biggest health crisis in a century.

In other words, everyone is hacking everyone with the goal of stealing key vaccine information. And that makes a lot of sense. The world is struggling with a type of crisis that no one alive has gone through, and a vaccine is the silver bullet that may get us out of it, so of course everyone wants to know how everyone else is doing developing it.
