How RMM abuse gives attackers a way in that looks like business as usual
Overview
In the first quarter of 2026, researchers from Huntress discovered that 45% of endpoint-related security incidents involved the misuse of legitimate remote monitoring and management (RMM) software. This finding indicates that attackers are increasingly taking advantage of tools that IT teams use to manage systems remotely, making their activities appear normal and less suspicious. Huntress ranked various attack tactics by frequency and potential damage, placing RMM abuse at the top of the list. The implications of this trend are significant, as it suggests that organizations need to be more vigilant in monitoring their RMM software usage to prevent unauthorized access and potential data breaches. Companies should implement stricter controls and monitoring on RMM tools to mitigate these risks.
Key Takeaways
- Active Exploitation: This vulnerability is being actively exploited by attackers. Immediate action is recommended.
- Affected Systems: Remote Monitoring and Management (RMM) software
- Action Required: Implement stricter controls and monitoring on RMM tools.
- Timeline: Newly disclosed
Original Article Summary
Huntress found attackers using legitimate remote monitoring and management (RMM) software in 45% of the endpoint-related incidents it recorded in the first quarter of 2026. The security company also ranked 11 attack tactics by how often it sees them and how much damage each can do, and RMM abuse sits farthest right on the chart, the position for tactics it sees most often. IT teams use RMM tools to manage computers from anywhere, so an … More → The post How RMM abuse gives attackers a way in that looks like business as usual appeared first on Help Net Security.
