How RMM abuse gives attackers a way in that looks like business as usual
AI-summarised brief · reviewed before publication
Huntress reported that 45% of endpoint incidents in Q1 2026 involved attackers abusing legitimate remote monitoring and management (RMM) software, marking it as the most frequently observed tactic. The study ranked 11 attack methods by prevalence and damage, placing RMM abuse at the far right of the chart. Attackers install RMM tools such as Tiflux, then add additional remote‑access utilities like UltraVNC, Splashtop, and ScreenConnect, enabling persistent, covert control that mimics normal admin activity. The technique surged 277% year‑over‑year in 2025, underscoring its growing threat.
💡 Why It Matters
- · The rise of RMM abuse shows attackers exploiting trusted tools to bypass security controls, turning routine IT operations into covert attack vectors.
- · This trend forces organizations to scrutinize approved software and monitor for anomalous remote‑access activity.
