Post-exploitation techniques refer to the methods used by attackers after they have successfully compromised a system. These techniques allow them to maintain access, gather sensitive information, and expand their control over the network. Common actions include installing backdoors, escalating privileges, and moving laterally to other systems. These techniques are crucial for attackers to achieve their objectives, such as data theft or disruption. Tools like Mimikatz can be used to extract credentials, while PowerShell scripts may facilitate further exploitation. Understanding these techniques helps organizations strengthen their defenses against potential threats.
