Lateral movement is a post-compromise technique used by attackers to quietly move through a network, escalate privileges, and access critical systems or data. By leveraging stolen credentials, exploiting trusted protocols like WMI and SMB, and abusing built-in tools such as PowerShell and PsExec, adversaries can blend in with normal activity and remain undetected. Detecting and…

Vulnerability management is vital for cybersecurity but is limited to known assets, often leaving blind spots. External Attack Surface Management (EASM) enhances this by continuously identifying unknown risks and unmanaged resources. EASM provides real-time alerts and deeper visibility, enabling organizations to address potential threats effectively and secure their infrastructure.
