What exploit technique uses standard systems to perform intrusions?

The concept of "Living off the Land" refers to an exploit technique where attackers utilize existing tools and features available in the target systems rather than introducing their own malicious software. This approach allows them to blend in with normal network activity, making detection more difficult. By leveraging legitimate software and built-in functionalities, attackers can maintain persistence and execute their operations while minimizing the risk of raising alarms.

This technique often involves taking advantage of administrative tools, scripts, and other resources already present on a system, which helps evade traditional security measures that are designed to detect or block unauthorized software installations. In contrast, the other options either refer to different exploit mechanisms or specific types of malware rather than the strategic approach of using legitimate resources for exploitation.
