Best Practices for Good Endpoint Hardening | Huntress
Huntress outlines endpoint hardening best practices, citing exposed RDP, RMM tool abuse, and ClickFix social engineering as common SMB intrusion paths.
Huntress published defensive guidance on endpoint hardening for small and mid-sized businesses, drawing on observations from its SOC. The post describes common intrusion vectors: internet-exposed RDP brute-forced by automated scanners, phishing emails delivering attacker-controlled remote monitoring and management (RMM) tools, with Huntress reporting a 277% spike in RMM abuse in 2025, and ClickFix attacks using fake CAPTCHA pages that trick users into running malicious commands. Recommended controls include scanning for exposed RDP, SSH, and VPN interfaces, removing unneeded local admin rights, enabling Windows Defender tamper protection, disabling SMBv1, and standardizing on one approved remote access tool, guided by CIS and NIST frameworks.
- Internet-exposed RDP is a top intrusion vector, often brute-forced by automated scanners.
- Huntress reports a 277% spike in RMM tool abuse in 2025 via phishing-delivered remote access tools.
- ClickFix attacks use fake CAPTCHA pages to make users run malicious commands themselves.
- Recommended controls: cut local admin rights, disable SMBv1, enable Defender tamper protection.
- Layered, continuously maintained hardening is favored over one-off compliance checklists.
