Find out how hackers utilize living off the land techniques to navigate environments without detection and how to safeguard against these threats.

What is Living off the Land attack?

While the term was first coined in 2013, Living off the Land tools, techniques, and procedures (TTPs) have boomed in popularity in recent years. In part, this is because the traditional approach of defensive security — blocklisting file hashes, domains, and other traces of threats encountered in previous attacks — is ill-equipped to identify these attacks. So these stealthy, often fileless attacks, have pushed their way into the mainstream.

Definition and overview

Living off the Land is a strategy which involves threat actors leveraging the utilities readily available within the target organization’s digital environment to move through the cyber kill chain. This is a popular method because It is often cheaper, easier, and more effective to make use of an organization’s own infrastructure in an attempt to attack rather than writing bespoke malware for every heist.

How does Living off the Land attack work?

Living off the Land attacks have a particular history in highly organized, targeted hacking. Advanced Persistent Threat (APT) groups have long favored Living off the Land TTPs, since evasion is a top priority. And trends show that ransomware groups are opting for human-operated ransomware that relies heavily on Living off the Land techniques, instead of commodity malware.

Among some of the most commonly used tools exploited for nefarious purposes are Powershell, Windows Management Interface (WMI), and PsExec. These tools are regularly used by network administrators as part of their daily routines, and traditional security tools reliant on static rules and signatures often have a hard time distinguishing between legitimate and malicious use.

Living off the Land attack techniques

Before a threat actor turns your infrastructure against you in a Living off the Land attack, they must be able to execute commands on a targeted system. Therefore, Living off the Land attacks are a post-infection framework for network reconnaissance, lateral movement, and persistence.

Once a device is infected, there are hundreds of system tools at the attacker’s disposal – these may be pre-installed on the system or downloaded via Microsoft-signed binaries. And, in the wrong hands, other trusted third-party administration tools on the network can also turn from friend to foe.

As Living off the Land techniques evolve, a single typical attack is hard to determine. However, we can group these TTPs in broader categories.

Microsoft-signed Living off the Land TTPs

Microsoft is ubiquitous in the business world and across industries. The Living off the Land Binaries and Scripts (LOLBAS) project aims to document all Microsoft-signed binaries and scripts that include functionality for APT groups in Living off the Land attacks. To date, there are 135 system tools on this list that are vulnerable to misuse, each aiding a different objective. These could be the creation of new user accounts, data compression and exfiltration, system information gathering, launching processes on a target destination or even the disablement of security services. Both Microsoft’s documentation of vulnerable pre-installed tools and the LOLBAS project are growing, non-exhaustive lists.

Command line exploitation

When it comes to delivering a malicious payload to the target, WMI (WMIC.exe), the command line tool (cmd.exe), and PowerShell (powershell.exe) were used most frequently by attackers, according to a recent study. These commonly exploited command line utilities are used during the configuration of security settings and system properties, provide sensitive network or device status updates, and facilitate the transfer and execution of files between devices.

Specifically, the command line group shares three key traits:

  1. They are readily available on Windows systems.
  2. They are frequently used by most administrators or internal processes to perform everyday tasks.
  3. They can perform their core functionalities without writing data to a disk.

Mimikatz

Mimikatz differs from other tools in that it is not pre-installed on most systems. It is an open-source utility used for the dumping of passwords, hashes, PINs and Kerberos tickets. While some network administrators may use Mimikatz to perform internal vulnerability assessments, it is not readily available on Windows systems.

Traditional security approaches used to detect the download, installation, and use of Mimikatz are often insufficient. There exists a wide range of verified and well documented techniques for obfuscating tooling like Mimikatz, meaning even an unsophisticated attacker can subvert basic string or hash-based detections.

Tips for stopping Living off the Land attacks

Living off the Land techniques have proven incredibly effective at enabling attackers to blend into organizations’ digital environments. It is normal for millions of credentials, network tools, and processes to be logged each day across a single digital ecosystem. So how can defenders spot malicious use of legitimate tools amidst this digital noise?

Network hygiene: As with most threats, basic network hygiene is the first step. This includes implementing the principle of least privilege, de-activating all unnecessary programs, setting up software whitelisting, and performing asset and application inventory checks. However, while these measures are a step in the right direction, with enough time a sophisticated attacker will always manage to work their way around them.

Self-Learning AI technology: This technology, exclusive to Darktrace, has become fundamental in shining a light on attackers using an organization’s own infrastructure against them. It learns any given unique digital environment from the ground up, understanding the ‘pattern of life’ for every device and user. Living off the Land attacks are therefore identified in real time from a series of subtle deviations. This might include a new credential or unusual SMB / DCE-RPC usage.

Its deep understanding of the business enables it to spot attacks that fly under the radar of other tools. With a Living off the Land attack, the AI will recognize that although usage of particular tool might be normal for an organization, the way in which that tool is used allows the AI to reveal seemingly benign behavior as unmistakably malicious.

Example of Self-Learning AI

Self-Learning AI might observe the frequent usage of Powershell user-agents across multiple devices, but will only report an incident if the user agent is observed on a device at an unusual time.

Similarly, Darktrace might observe WMI commands being sent between thousands of combinations of devices each day, but will only alert on such activity if the commands are uncommon for both the source and the destination.

And even the subtle indicators of Mimikatz exploitation, like new credential usage or uncommon SMB traffic, will not be buried among the normal operations of the infrastructure.

Final thoughts on Living off the Land techniques

Living off the Land techniques aren’t going away any time soon. Recognizing this, security teams are beginning to move away from ‘legacy’-based defenses that rely on historical attack data to catch the next attack, and towards AI that uses a bespoke and evolving understanding of its surroundings to detect subtle deviations indicative of a threat – even if that threat makes use of legitimate tools.

Darktrace Recognized as the Only Visionary in the 2025 Gartner® Magic Quadrant™ for CPS Protection Platforms

Default blog imageDefault blog image

We are thrilled to announce that Darktrace has been named the only Visionary in the inaugural Gartner® Magic Quadrant™ for Cyber-Physical Systems (CPS) Protection Platforms. We feel This recognition highlights Darktrace’s AI-driven approach to securing industrial environments, where conventional security solutions struggle to keep pace with increasing cyber threats.

A milestone for CPS security

It's our opinion that the first-ever Gartner Magic Quadrant for CPS Protection Platforms reflects a growing industry shift toward purpose-built security solutions for critical infrastructure. As organizations integrate IT, OT, and cloud-connected systems, the cyber risk landscape continues to expand. Gartner evaluated 17 vendors based on their Ability to Execute and Completeness of Vision, establishing a benchmark for security leaders looking to enhance cyber resilience in industrial environments.

We believe the Gartner recognition of Darktrace as the only Visionary reaffirms the platform’s ability to proactively defend against cyber risks through AI-driven anomaly detection, autonomous response, and risk-based security strategies. With increasingly sophisticated attacks targeting industrial control systems, organizations need a solution that continuously evolves to defend against both known and unknown threats.

AI-driven security for CPS environments

Securing CPS environments requires an approach that adapts to the dynamic nature of industrial operations. Traditional security tools rely on static signatures and predefined rules, leaving gaps in protection against novel and sophisticated threats. Darktrace / OT takes a different approach, leveraging Self-Learning AI to detect and neutralize threats in real time, even in air-gapped or highly regulated environments.

Darktrace / OT continuously analyzes network behaviors to establish a deep understanding of what is “normal” for each industrial environment. This enables it to autonomously identify deviations that signal potential cyber threats, providing early warning and proactive defense before attacks can disrupt operations. Unlike rule-based security models that require constant manual updates, Darktrace / OT improves with the environment, ensuring long-term resilience against emerging cyber risks.

Bridging the IT-OT security gap

A major challenge for organizations protecting CPS environments is the disconnect between IT and OT security. While IT security has traditionally focused on data

protection and compliance, OT security is driven by operational uptime and safety, leading to siloed security programs that leave critical gaps in visibility and response.

Darktrace / OT eliminates these silos by providing unified visibility across IT, OT, and IoT assets, ensuring that security teams have a complete picture of their attack surface. Its AI-driven approach enables cross-domain threat detection, recognizing risks that move laterally between IT and OT environments. By seamlessly integrating with existing security architectures, Darktrace / OT helps organizations close security gaps without disrupting industrial processes.

Proactive OT risk management and resilience

Beyond detection and response, Darktrace / OT strengthens organizations’ ability to manage cyber risk proactively. By mapping vulnerabilities to real-world attack paths, it prioritizes remediation actions based on actual exploitability and business impact, rather than relying on isolated CVE scores. This risk-based approach enables security teams to focus resources where they matter most, reducing overall exposure to cyber threats.

With autonomous threat response capabilities, Darktrace / OT not only identifies risks but also contains them in real time, preventing attackers from escalating intrusions. Whether mitigating ransomware, insider threats, or sophisticated nation-state attacks, Darktrace / OT ensures that industrial environments remain secure, operational, and resilient, no matter how threats evolve.

AI-powered incident response and SOC automation

Security teams are facing an overwhelming volume of alerts, making it difficult to prioritize threats and respond effectively. Darktrace / OT’s Cyber AI Analyst acts as a force multiplier for security teams by automating threat investigation, alert triage, and response actions. By mimicking the workflow of a human SOC analyst, Cyber AI Analyst provides contextual insights that accelerate incident response and reduce the manual workload on security teams.

With 24/7 autonomous monitoring, Darktrace / OT ensures that threats are continuously detected and investigated in real time. Whether facing ransomware, insider threats, or sophisticated nation-state attacks, organizations can rely on AI-driven security to contain threats before they disrupt operations.

Trusted by customers: Darktrace / OT recognized in Gartner Peer Insights

Survey Findings: AI Cybersecurity Priorities and Objectives in 2025

Default blog imageDefault blog image

AI is changing the cybersecurity field, both on the offensive and defensive sides. We surveyed over 1,500 cybersecurity professionals from around the world to uncover their attitudes, understanding, and priorities when it comes to AI cybersecurity in 2025. Our full report, unearthing some telling trends, is available now.  

Download the full report to explore these findings in depth

It is clear that security professionals know their field is changing fast, and that AI will continue to influence those changes. Our survey results show that they are aware that the rise of AI will require them to adopt new tools and learn to use them effectively. Still, they aren’t always certain about how to plan for the future, or what to invest in.

The top priorities of security stakeholders for improving their defenses against AI-powered threats include augmenting their existing tool stacks with AI-powered solutions and improving integration among their security tools.

Figure 1: Year-over-year changes to the priorities of securitystakeholders.

Increasing cybersecurity staff

As was also the case last year, security stakeholders are less interested in hiring additional staff than in adding new AI-powered tools onto their existing security stacks, with only with 11% (and only 8% of executives) planning to increase cybersecurity staff in 2025.

This suggests that leaders are looking for new methods to overcome talent resource shortages.

Adding AI-powered security tools to supplement existing solutions

Executives are particularly enthusiastic about adopting AI-driven tools. Within that goal, there is consensus about the qualities cyber professionals are looking for when purchasing new security capabilities or replacing existing products.

  • 87% of survey respondents prefer solutions that are part of a broader platform over individual point products

These results are similar to last year’s, where again, almost nine out of ten agreed that a platform-oriented security solution was more effective at stopping cyber threats than a collection of individual products.

  • 88% of survey respondents agree that the use of AI within the security stack is critical to freeing up time for security teams to become more proactive, compared to reactive

AI itself can contribute to this shift from reactive to proactive security, improving risk prioritization and automating preventative strategies like Attack Surface Management (ASM) and proactive exposure management.

  • 84% of survey respondents prefer defensive AI solutions that do not require the organization’s data to be shared externally

This preference may reflect increasing attention to the data privacy and security risks posed by generative AI (gen AI) adoption. It may also reflect growing awareness of data residency requirements and other restrictions that regulators are imposing.

Improving cybersecurity awareness training for end users

Based on the survey results, practitioners in SecOps are more interested in improving security awareness training.

This goal is not necessarily mutually exclusive from the addition of AI tools. For example, teams can leverage AI to build more effective security awareness training programs, and as gen AI tools are adopted, users will need to be taught about data privacy and associated security risks.

Looking towards the future

One conclusion we can draw from the attitudinal shifts from last year’s survey to this year’s: while hiring more security staff might be a nice-to-have, implementing AI-powered tools so that existing employees can work smarter is increasingly viewed as a must-have.

However, trending goals are not just about managing resources, whether headcount or AI investments, to keep up with workloads. Existing end users must also be trained to follow safe practices while using established and newly adopted tools.

Security professionals, including executives, SecOps, and every role in between, continue to shift their identified challenges and priorities as they gear up for the coming year in the Era of AI.
