Critical N-able N-central Zero-Day Exploited: MSP Platform Breach Threatens Downstream Web3 Infrastructure

Security researchers and response teams disclosed active exploitation of a critical vulnerability in N-able N-central, a flagship Remote Monitoring and Management (RMM) platform heavily utilized by Managed Service Providers (MSPs) globally.
