Introduction
Motivation
In the realm of cybersecurity, ‘Living off the Land’ (LotL) attacks represent a growing threat. These attacks exploit dual-use tools—pre-installed software that can serve both legitimate and malicious purposes—thereby avoiding detection by systems like Endpoint Detection and Response (EDR) and Security Information and Event Management (SIEM). Utilizing tools like Remote Access Tools (RATs) for activities such as data exfiltration and lateral movement, these attacks are difficult to detect due to their use of trusted, native applications. The rise of fileless malware, increasing from 40% in 2018 to 71% in 2023, highlights the effectiveness and stealth of LotL tactics.

This tool specifically targets the detection of LotL tactics that exploit dual-use tools, such as Remote Access Tools (RATs), which are often used legitimately but can also facilitate malicious activities. By generating precise Indicators of Compromise (IoCs) and creating tailored detection rules, our tool effectively identifies and mitigates the subtle techniques employed in these stealth attacks.
Integration with Security Information and Event Management (SIEM) systems is a key feature of the tool, enabling the automation of IoC collection and analysis. This integration not only streamlines the detection process but also significantly reduces the time needed to respond to threats, thereby strengthening overall security posture. By assisting in the early stages of attack detection, our tool plays a crucial role in preventing the establishment of attackers within the network and thwarting their attempts at data exfiltration, lateral movement, and persistence.
