In his post earlier this week, OODA Loop Contributor Emilio Iasiello provided the initial coverage of a “cluster of activity” linked to China, targeting networks across U.S. critical infrastructures and Guam:  Chinese Cyber Activities Against Critical Infrastructure Raises the Stakes in U.S.-China Relations.   As is always the case with Emilio’s weekly contribution here at OODA Loop, it is worth a read.  The advisory referenced by Emilio in his post  – People’s Republic of China State-Sponsored Cyber Actor Living off the Land to Evade Detection – dovetails with our analysis in April of the State Department turning its strategic focus towards cyber-threat vectors in Guam, Albania, and Costa Rica.  This People’s Republic of China (PRC) state-sponsored cyber actor, also known as Volt Typhoon or Bronze Silhouette, requires additional coverage.
