Adversary simulation: what you need to know

UK NCSC publishes guidance on adversary simulation, comparing full spectrum and assumed breach approaches across prerequisites, testing, and reporting phases.

NCSC guidance describes two adversary simulation approaches: full spectrum, starting outside the network with an end-to-end attack, and assumed breach, starting from an internal foothold. The preferred methodology spans three phases - prerequisites (scoping, passive reconnaissance, preparation), testing (active reconnaissance, initial access, internal phase, cleanup), and reporting. The document distinguishes adversary simulation from penetration testing and stresses customer-defined objectives and minimal information sharing.

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.
