I'm not aware of the specifics of this particular instance.
What I can tell you is that we proactively investigate and hunt for cyber-espionage campaigns: efforts by foreign governments to spy on innocent people around the world. We regularly report on that work through our quarterly reports, where we describe the enforcements we've taken, and then we share information about any operations that we do identify with others in industry so they can take action as well.
One of the things we've seen is that these types of campaigns are broad efforts that target the Internet broadly—multiple platforms—and often involve off-platform activity as well. Investigating these, disclosing information on them and then sharing that information with other parties is a really important part of tracking and countering these adversaries.
