The China-lined threat actor behind the zero-day exploitation of security flaws in Microsoft Exchange servers in January 2021 has shifted its tactics to target the information technology (IT) supply chain as a means to obtain initial access to corporate networks.

The adversarial collective is assessed to be "well-resourced and technically efficient," swiftly putting to use exploits for zero-day vulnerabilities in edge devices for opportunistic attacks that allow them to scale their attacks at scale and across a wide range of sectors and regions. This includes information technology (IT) services and infrastructure, remote monitoring and management (RMM) companies, managed service providers (MSPs) and affiliates, healthcare, legal services, higher education, defense, government, non-governmental organizations (NGOs), energy, and others located in the United States and throughout the world.
