The Cybersecurity and Infrastructure Security Agency (CISA), National Security Agency (NSA), Federal Bureau of Investigation (FBI), Australian Signals Directorate’s (ASD’s) Australian Cyber Security Centre (ACSC), Canadian Cyber Security Centre (CCCS), and New Zealand’s National Cyber Security Centre (NCSC-NZ) warn that People’s Republic of China (PRC)-affiliated threat actors compromised networks of major global telecommunications providers to conduct a broad and significant cyber espionage campaign.

Although tailored to network defenders and engineers of communications infrastructure, this guide may also apply to organizations with onpremises enterprise equipment.
