Intent-Based Networking

Living off the land (LOTL) is a fileless malware cyberattack technique where a threat actor uses legitimate tools and features already present in the target system to avoid detection and carry on a cyberattack . In this type of assault, the assailant does not utilize any malware that can be detected. Rather, they take advantage of those built-in features in the operating system, administrative tools, and scripts to hijack the system and recover critical information.

LOTL is a widely used approach by hackers because it makes it hard for security systems to notice the intrusion. The attacker employs the available features of the system in a normal manner so as not to draw any attention, and the utilities employed in the attack are generally not easy to spot by conventional preventative measure .

Types of LOTL attacks

Cybercriminals are increasingly using LOTL attacks because they are effective in bypassing common traditional security apparatus. Social engineering is an aspect of these attacks, which makes them more sophisticated because legitimate tools and processes are used for nefarious functions . The following LOTL techniques may be used:

• Binary Planting
• Registry Run Keys
• Fileless Malware
• PowerShell-Based Attacks

Preventing Living-Off-the-Land Attacks

Organizations need to enhance their threat identification, detection, and incident response (TDIR) processes to combat the threats arising from LOTL attacks, utilizing processes such as automation, machine learning, and behavior analysis . Such upgrades allow quick detection and action on threats providing a lead to the organizations over their enemies.

The following fundamental actions are essential for the defense:

• Prioritize Visibility: Employ proactive detection techniques so that an outflow of sensitive information can be controlled.
• Enable Comprehensive Logging: Lockdown system tools e.g. PowerShell where users can abuse to perform actions outside their usual tendencies e.g.
• Leverage Advanced Tools: Engage in endpoint monitoring and conduct behavioral analytics to respond to suspicious acts.
• Use User & Entity Behavioral Analytics: Understand what is ‘normal’ for a given user and what may constitute a red flag for a potential LOTL attack.
• Continually Review Detections: Continue improving detection capabilities for emerging threats.
• Adopt Zero Trust Architecture: Limit the plaque of attackers by establishing tamper proof borders and erecting wall on corridors.

These actions taken together enhance the overall capability of the organization to defend and to recover from LOTL threats.
