Living-off-the-land (LOTL) attacks are an increasingly popular tactic among cybercriminals. An advanced persistent threat (APT), an LOTL attack involves using legitimate and trusted system tools to launch a cyberattack and evade detection. In this article, we will explore the different aspects of LOTL attacks and how to prepare for, and mitigate the risk of, this sophisticated attack.

Living-Off-the-Land (LOTL) Attacks

What Is a Living-Off-the-Land (LOTL) Attack?

An LOTL attack is a type of cyberattack where a hacker uses legitimate tools and features already present in the target system to avoid detection and carry on a cyberattack. In this type of attack, the hacker does not use any malicious software or code that can be easily detected by traditional security solutions. Instead, they leverage the operating system’s built-in capabilities, administrative tools, and batch files to control the system and steal sensitive information.

LOTL is a popular technique among hackers because it makes it difficult for security systems to detect the attack. The hacker uses existing system functionalities that do not raise any suspicion, and the tools used in the attack are often difficult to detect by standard security solutions. As the attack uses legitimate tools, it can be difficult to distinguish the attack from regular system activity.

Some examples of LOTL attacks include using PowerShell or the Windows Management Instrumentation (WMI) to carry out malicious activities, using built-in scripting languages like Python or Ruby to create malicious scripts, or utilizing scheduled tasks and registry keys to execute malicious code. We’ll discuss these in detail in the section below.

Types of LOTL Attacks

LOTL attacks are becoming increasingly popular among cybercriminals due to their effectiveness in bypassing traditional security measures. These attacks involve the use of legitimate tools and techniques to carry out malicious activities, making them difficult to detect. There are several types of LOTL attacks, including binary planting, Registry Run Keys, fileless malware, and PowerShell-based attacks. Each of these attacks poses a significant threat to organizations and individuals alike and requires proactive measures to prevent and detect.

Binary Planting

Binary planting, also known as DLL hijacking or DLL side-loading, is a type of LOTL attack that involves replacing a legitimate DLL file with a malicious one. When an application tries to use the legitimate DLL, it unknowingly loads the malicious one instead, allowing the attacker to execute code on the victim’s system. This attack can be particularly dangerous because it can be used to exploit applications that run with elevated privileges, such as system-level services and administrative tools. Detection of this attack can be difficult since it often appears like a legitimate process.

Registry Run Keys

Registry Run Keys are a technique used by attackers to run their malicious code on a victim’s system at startup. The attackers insert their malware into the registry key that contains instructions to execute a specific program at startup. The code can be added to any of the Registry Run Keys, such as:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run, or


This type of attack is particularly dangerous because it allows an attacker to maintain persistence on an infected system, even after rebooting. It can also allow the attacker to escalate privileges.

Fileless Malware

Fileless malware is an advanced type of LOTL attack that bypasses traditional antivirus software by residing in the computer’s memory instead of in the file system. The attackers use scripting languages such as PowerShell or Windows Management Instrumentation (WMI) to execute code directly in memory. As a result, there is no file to scan, making it more difficult to detect. Fileless malware can be used to steal sensitive data, install backdoors, or carry out various other malicious activities, and thus poses a significant threat to organizations that rely on traditional antivirus solutions.

PowerShell-based Attacks

PowerShell-based attacks use Windows PowerShell, a powerful scripting language built into Windows, to execute malicious code. Attackers can use PowerShell to bypass traditional antivirus and other security measures by using PowerShell scripts to execute commands and run malware. PowerShell-based attacks can be used to steal credentials, download additional malware, and spread throughout a network. Since PowerShell is a legitimate tool used by administrators, detection of this attack can be difficult, particularly if the attacker has gained privileges or access to an administrative account.

How LOTL Attacks Work

LOTL attacks work by exploiting trusted system tools and applications to evade detection. Attackers use preexisting vulnerabilities and weaknesses in these tools to execute malicious code and maintain persistence on the system.

Exploiting Trusted System Tools

LOTL attacks heavily rely on exploiting trusted system tools, such as PowerShell, Windows Management Instrumentation (WMI), and command-line interfaces. Attackers use these tools to execute commands, modify system configurations, and perform other tasks without alerting users or security systems. Because these tools are trusted by users, attackers can easily blend in with legitimate users and avoid detection.

Leveraging Preexisting Vulnerabilities

LOTL attacks can also leverage preexisting vulnerabilities within the target system. Attackers can exploit these vulnerabilities to gain access to sensitive information or execute commands on the system. Because these vulnerabilities already exist within the system, attackers do not need to create them from scratch or use complex hacking techniques. Instead, they can simply use a known vulnerability to gain access.

Hiding Malicious Code Within Benign Files

Finally, LOTL attacks can involve hiding malicious code within benign files. Attackers can, for example, embed malicious code within trusted file types, such as PDFs or Word documents, and trick users into downloading or opening them. Once the user opens the file, the embedded code executes and gives the attacker access to the system. This type of attack is known as a fileless attack because it does not require the attacker to install any software on the target system.

Tools Used by Cybercriminals in LOTL Attacks

The following tools are commonly used by attackers in various cyberattacks, including LOTL attacks. They provide a wide range of capabilities, including network scanning, remote execution, password cracking, and exploitation of vulnerabilities. These tools are often used in combination to gather information, gain access to systems, and maintain persistence on the target network. The use of these tools requires a high level of technical skill and knowledge, and they are also popular among security professionals for penetration testing and vulnerability assessments.

How to Detect LOTL Attacks

Detecting LOTL attacks can be challenging because attackers use trusted system tools and existing vulnerabilities to avoid detection. There are, however, some strategies that organizations can use to detect and prevent these attacks. For example, monitoring system logs and network traffic can help detect unusual or suspicious activity. Additionally, using endpoint detection and response (EDR) security software can help detect and respond to LOTL attacks in real time. Regular vulnerability scanning and patching can also help prevent attackers from exploiting known vulnerabilities within the system.

The Impact of LOTL Attacks

The impact of LOTL attacks can be significant, ranging from data theft to complete system compromise. These attacks can result in the loss of sensitive information, business disruption, financial loss, and damage to an organization’s reputation. Real-life examples of LOTL attacks include the Petya and NotPetya attacks in 2017. These attacks caused significant damage to businesses and organizations worldwide. They were a type of ransomware that encrypted the victim’s files and demanded payment in exchange for the decryption key. However, unlike traditional ransomware attacks, the Petya and NotPetya malware spread rapidly through networks using multiple infection vectors, including exploiting vulnerable software. NotPetya was particularly damaging, as it was disguised as ransomware but was actually designed to destroy data on infected machines. These attacks were estimated to have caused losses of billions of dollars globally and served as a reminder of the importance of robust cybersecurity practices. The economic consequences of LOTL attacks can be severe, especially for small and medium-sized businesses that may not have the resources to recover from such attacks.

How to Prevent Living-Off-the-Land (LOTL) Attacks

LOTL attacks are crucial for organizations to maintain the integrity and security of their sensitive information. These attacks can be difficult to detect and can cause significant damage. Implementing certain measures, however, can help reduce the risk of LOTL attacks. These measures include:

Limit the Use of Scripting Languages

LOTL attacks rely on the use of scripting languages to execute malicious code. Limiting the use of scripting languages or implementing strict controls can reduce the risk of these attacks.

Monitor System Activity

Implement a robust system for monitoring system activity and access to files. This can help detect unusual access patterns that could be indicative of an LOTL attack.

Update Software Regularly

Regular software updates can patch vulnerabilities that could be exploited by LOTL attacks. Make sure that all software and applications used within the organization are regularly updated to the latest version.

Implement Least-privilege Access Controls

Limiting access to sensitive data and resources can help reduce the risk of LOTL attacks. Implement a least-privilege access control policy, which can help ensure that users only have access to the data and resources they need to perform their job functions.

Implement Strong User Authentication

Strong user authentication measures, such as multi-factor authentication, can help prevent unauthorized access to sensitive data and resources.

Educate Users

Users can unwittingly introduce vulnerabilities into the system by downloading malicious software or clicking on phishing links. Regular employee training can help educate users on good security practices and reduce the likelihood of LOTL attacks.
