Severity: High
Summary
Researchers investigated the exploitation of the zero-day vulnerability CVE-2026-18577 in N-able N-central, where attackers gained initial access and deployed legitimate Remote Monitoring and Management (RMM) tools to establish persistent remote access. The intrusion involved post-exploitation activities such as reconnaissance, credential access, and lateral movement while abusing trusted administration software to evade detection. The campaign underscores the importance of promptly patching internet-facing RMM infrastructure, monitoring for unauthorized RMM deployments, and detecting suspicious post-compromise behavior.
