Living-off-the-land attacks operate by leveraging commonly used tools, turning them into instruments of cyber threat. Among these tools, PowerShell, Windows Management Instrumentation (WMI), and scripting languages stand out as primary vectors for unauthorized use.

LOTL attacks stand out for their ability to operate without leaving any traceable files behind, earning them the moniker of “fileless malware.” The absence of executable files or traditional malware makes it challenging for numerous cybersecurity suites to detect these activities, leaving them oblivious to potentially suspicious events.

Living-off-the-land (LOTL) attacks are not new; they’ve been around for a while. Every major operating system has vulnerabilities that make it possible for LOTL attacks to happen. Despite constant efforts, why is it so hard for cybersecurity teams to fully close these security gaps? Let’s explore a few examples to understand the complexity behind it.

Dual-use tools are legitimate computer tools and software that attackers can use in the wrong way.
e.g. Microsoft’s PsExec, WMI, PowerShell

Fileless persistence is a sneaky kind of attack where bad actors can leave harmful stuff on your computer, even after you restart it. It’s called fileless malware, and it’s like hiding bad scripts in the behind-the-scenes part of your computer called the Windows Registry, messing with how things work.

Memory-only Threats are like invisible invaders that execute their harmful code directly in your computer’s memory. This means they leave no traces on your computer’s storage, making them hard to detect. You might hear them called “fileless attacks,” but this term can include attacks that leave a tiny mark on your storage, like those using the Windows registry. An example of a true memory-only attack is the notorious “Mirai” malware that targeted IoT devices. Mirai lived in the device’s memory, so restarting the device cleaned it. Another recent case is the “Wannacry” ransomworm, using the “EternalBlue” exploit. Memory-only attacks are also seen in Point-of-Sale (PoS) malware, where they sneakily access the device’s memory to steal card information.

Non-portable executable file attacks. Some computer files, known as Non-Portable Executable (PE) files, can be tricky. They can infect libraries and tools, like JavaScript or PowerShell, without needing to install typical files you might be familiar with, such as .exe or .dll files. Even seemingly harmless files like .doc files with macros and scripts can be carriers of infection.
This means that tools you usually trust can accidentally carry and spread infections. It’s like a sneaky way for bad stuff to hide in the tools you use every day.

In today’s dynamic digital landscape, the threat of cyber attacks, including the insidious LOTL attacks, is ever-present. As businesses evolve, so do the tactics of malicious actors looking to exploit vulnerabilities and compromise sensitive information.
