Re: Cybersecurity Threat Alert – N-central Vulnerability

The New York State Department of Financial Services (“DFS” or “Department”) is issuing this alert to DFS-regulated entities regarding an active cybersecurity campaign targeting a security vulnerability in the remote monitoring and management system N-central, developed and maintained by N-able (“Alert”). N-central is used by some managed service providers (“MSPs”) to centrally monitor, patch, and remotely access their customers’ services and endpoints (also referred to as Remote Monitoring and Management services or RMM services).

Threat actors are targeting a Known Exploited Vulnerability in N-central to compromise MSP environments. Once access is obtained, threat actors may create or register for new services, allowing continued access even after compromised N-central credentials are revoked. Attackers are using a compromised MSP’s environment to move laterally into their customer’s networks and information systems with administrator network privileges.

DFS-regulated entities should promptly determine whether N-central is used within their environment or by any MSP or other Third-Party Service Provider that supports their information systems. Where N-central is used, DFS-regulated entities should work with their service providers to assess and mitigate potential exposure, including reviewing N-central activity for evidence of unauthorized or persistent access; verifying that applicable security updates, including software patches and other threat mitigation steps, have been implemented; and evaluating whether any systems or credentials were affected.

While the vulnerability addressed in this Alert is likely limited to MSPs, the senior governing bodies and senior officers of DFS-regulated entities must actively engage in cybersecurity risk management, including through monitoring and oversight of third-party service providers. To that end, the Department expects DFS-regulated entities that may be exposed to cybersecurity risk related to the N-central vulnerability to appropriately manage this risk through due diligence and engagement with Third-Party Service Providers on this issue. Additionally, DFS-regulated entities should ensure that they continue to report all Cybersecurity Incidents to DFS, including those originating at Third-Party Service Providers, as required by 23 NYCRR § 500.17.
