Defending Against China-Nexus Covert Networks of Compromised Devices
Summary
This advisory, released by multiple international cybersecurity agencies, details a shift in tactics by China-nexus cyber actors towards using large networks of compromised devices to mask their malicious activity. It aims to equip network defenders with the necessary knowledge and tools to counter this evolving threat.
IFF Assessment
The advisory describes a new and widespread tactic used by state-sponsored threat actors, which increases the difficulty for defenders to detect and attribute cyber activity.
Defender Context
Defenders should be aware of the increasing use of compromised infrastructure as proxies by threat actors, particularly those linked to China. This tactic makes attribution more challenging and requires enhanced network monitoring for unusual traffic patterns and compromised device activity.
