Previous CISA Chief Jen Easterly discusses a new global intelligence sharing cooperative:

Traditionally, China, Russia, Iran, and North Korea have collaborated to a degree on military and intelligence issues, yet variations in language, culture, politics, and technological advancement have impeded deeper collaboration, particularly in cyberspace. Nonetheless, evolving geopolitical conditions could compel these nations towards a more formalized intelligence-sharing alliance. This potential “Four Eyes” partnership would be driven by shared adversaries and strategic goals, including bolstered ability to withstand economic sanctions and assist in proxy conflicts.
