The technique that the threat actor used after penetrating the system and looking to move through the network with their elevated position is called "lateral movement." Lateral movement is a technique that hackers use to navigate through a network to find high-value targets or sensitive information. Once a threat actor gains access to a network, they use lateral movement techniques to escalate privileges and move laterally across the network, looking for valuable data or systems to attack. Lateral movement can include techniques like pass-the-hash attacks, pass-the-ticket attacks, and using stolen credentials to gain access to different parts of the network. By moving laterally, attackers can evade detection and gain access to more valuable targets within a network. It is crucial to detect and prevent lateral movement to protect sensitive information and prevent further attacks. Organizations can use techniques like network segmentation, access controls, and monitoring for unusual activity to prevent lateral movement attacks.
