CISA, NSA, and MS-ISAC Release Advisory on the Malicious Use of RMM Software

Today, the Cybersecurity and Infrastructure Security Agency (CISA), the National Security Agency (NSA), and the Multi-State Information Sharing and Analysis Center (MS-ISAC) released joint Cybersecurity Advisory (CSA) Protecting Against Malicious Use of Remote Monitoring and Management Software. The advisory describes a phishing scam in which cyber threat actors maliciously use legitimate remote monitoring and management (RMM) software to steal money from victim bank accounts.

CISA encourages network defenders to review the advisory for indicators of compromise, best practices, and recommended mitigations, which highlights the threat of additional types of malicious activity using RMM, including its use as a backdoor for persistence and/or command and control (C2).
