The remote access blind spot: An analysis of RMM tool risk for SMBs

Acronis telemetry analysis of 1.8M endpoints (Jan 2025–Mar 2026) shows widespread RMM/tool sprawl—63% of endpoints run two or more remote access tools—creating a large attack surface that threat actors increasingly exploit by installing legitimate, open-source, or leaked RMM tools (notably MeshAgent and Ammyy) to blend in with normal admin traffic; the report highlights high-impact vulnerabilities disclosed in RMM products, frequent RDP use in intrusions, campaign-driven spikes in incidents, and the disproportionate presence of certain tools in malicious activity versus legitimate usage, with follow-up guidance promised in part two.
