Lateral movement refers to the techniques attackers use to move deeper within a compromised network after gaining initial access. Instead of launching an attack immediately after a breach, adversaries will spend time exploring, pivoting between systems, and searching for higher-value targets. This could include domain controllers, file servers, databases, or endpoints used by privileged users.
The process typically starts with a foothold—often through phishing, credential theft, or exploiting a vulnerable device. From there, attackers use tools and legitimate credentials to move laterally between systems, usually avoiding detection by blending in with normal activity.
Why Lateral Movement Is So Dangerous
The main danger of lateral movement is that it transforms a single compromised system into a launchpad for full network compromise. It’s not just about breaching one asset—it’s about gaining access to everything else behind it.
Since attackers often use valid credentials and native tools (like PowerShell or WMI), lateral movement is hard to detect. This stealth allows them to remain inside a network for weeks or months without being noticed, gathering intelligence, escalating privileges, and preparing for the final objective—whether that’s data theft, ransomware deployment, or sabotage.

Common Techniques Used in Lateral Movement
Attackers use a wide range of techniques for lateral movement, often relying on the same tools used by system administrators. These tactics are part of the MITRE ATT&CK framework and include:
One common method is Pass-the-Hash, where attackers use hashed versions of passwords to authenticate across systems without knowing the actual password. Another widely used tactic is Pass-the-Ticket, where adversaries abuse Kerberos tickets to access other services within the network.
Remote Desktop Protocol (RDP) is frequently exploited if it’s poorly secured or exposed internally. Windows Management Instrumentation (WMI) and PowerShell Remoting are also abused to execute commands remotely across systems. These tools are legitimate, so their use doesn’t always raise immediate alarms.
Attackers may also use lateral movement frameworks such as Cobalt Strike, Mimikatz, or Impacket to automate movement and escalate privileges.
