Beijing-linked hackers is a generic designation for intrusion activity assessed as linked to China and observed exploiting the React Server Components remote code execution vulnerability known as React2Shell (CVE-2025-55182). The activity has been associated with active exploitation of internet-exposed vulnerable applications shortly after disclosure, alongside broader opportunistic exploitation by multiple intrusion clusters. Reported operations involved leveraging the vulnerability for initial access against affected organizations across multiple sectors. Available information supports exploitation activity and Chinese nexus, but does not identify a specific named intrusion set, sub-group, or stable alias beyond the generic descriptor.
