China's Cyber Attacks Target U.S. Infrastructure and Pacific Islands.

Chinese government hacking group "Volt Typhoon" installed a malicious script called "web shell" in telecommunications systems in Guam and elsewhere in the United States, according to Microsoft and American intelligence agencies. The code could enable remote access to a server and pierce firewalls, potentially leading to destructive attacks. The group is part of a state-sponsored Chinese effort aimed at critical infrastructure, maritime operations, and transportation. The intrusion appears to be an espionage campaign, but the Chinese could use it for offensive attacks. The focus on Guam raises concerns about China's capabilities and willingness to attack or choke off Taiwan.
