The US authoring agencies believe that “Volt Typhoon”, a group sponsored by the People’s Republic of China, is trying to position themselves on IT networks using living off the land (LOTL) techniques. They aim to carry out cyber attacks against critical infrastructure in the US in case of a major crisis or conflict with the US. The fact sheet alerts leaders of critical infrastructure about this urgent risk and provides guidance on how to protect their organization from this threat.
CISA and its partners recommend that leaders of critical infrastructure organizations read the joint fact sheet to defend against the Volt Typhoon threat. For more information, see the guidance on identifying and mitigating Living off the Land Techniques. Visit Secure by Design for information on secure by design principles and practices.
