About this tag
Lateral movement is a key phase in cyberattacks where adversaries spread from an initial foothold to other systems within a network. On WindowsForum.com, discussions cover real-world examples like the Conficker worm, which exploited unpatched Windows systems to propagate rapidly, and NTLM vulnerabilities that enable privilege escalation across networks. Other threads highlight how threat actors use remote administration tools like ScreenConnect for initial access before moving laterally, and how unpatched Windows 10 systems after end-of-support become prime targets. Vulnerabilities in Windows RRAS and Azure VMs are also examined as potential vectors for lateral movement. These topics emphasize the importance of patch management, network segmentation, and monitoring to detect and block lateral movement in Windows environments.
