Image File Execution Options Injection Process Manipulating

Image File Execution Options Injection, also known as IFEO Injection, is a technique used by malware to evade detection and persist on a compromised system.

The technique involves modifying the Image File Execution Options (IFEO) registry key, which is used by the Windows operating system to set debugging options for executable files. When an executable file is launched, the operating …

COM Hijacking Process Manipulating

COM hijacking is a technique used by adversaries to insert malicious code into the Windows operating system through the Microsoft Component Object Model (COM).

COM is a system that allows software components to interact with each other, and adversaries can abuse this system to execute their own code in place of legitimate software. To achieve this, they alter references and …

Hiding Mechanisms Others

Malware often uses various techniques to hide its presence on a system and avoid detection. One common method is to modify or create entries in the system registry, which is a database of configuration settings for the operating system and installed applications. By modifying these settings, malware can hide itself from security software or other programs that might detect its …

Rootkit Defense Evasion [Mitre]

Adversaries may use rootkits to hide the presence of programs, files, network connections, services, drivers, and other system components. Rootkits are programs that hide the existence of malware by intercepting/hooking and modifying operating system API calls that supply system information.

Rootkits or rootkit enabling functionality may reside at the user or kernel level in the operating system or lower, to …

Hook Injection Process Manipulating

Hook injection is a technique used by malware to alter the behavior of internal functions in an operating system or application. This is typically achieved by inserting malicious code into existing function calls, allowing the malware to intercept and manipulate the normal flow of execution.

In the case of Windows, the SetWindowsHookEx function can be used by programs to install …

Obfuscated Files or Information: Stripped Payloads Defense Evasion [Mitre]

Adversaries may attempt to make a payload difficult to analyze by removing symbols, strings, and other human readable information. Scripts and executables may contain variables names and other strings that help developers document code functionality. Symbols are often created by an operating system’s linker when executable payloads are compiled. Reverse engineers use these symbols and strings to analyze code and …

SLDT, No Pill Sandbox Evasion

The No Pill technique is a method used by malware to determine whether it is running on a physical machine or a virtual machine. This technique relies on the fact that the Local Descriptor Table (LDT) is assigned to a processor, rather than to an operating system. On a physical machine, the location of the LDT will be zero, whereas …

Virtualization/Sandbox Evasion: System Checks Defense Evasion [Mitre]

Adversaries may employ various system checks to detect and avoid virtualization and analysis environments. This may include changing behaviors based on the results of checks for the presence of artifacts indicative of a virtual machine environment (VME) or sandbox. If the adversary detects a VME, they may alter their malware to disengage from the victim or conceal the core functions …

Unloading Sysmon Driver Anti-Monitoring

Sysmon is a tool that can be used to monitor system activity on Windows systems. It records various types of events, such as process creation, network connections, and registry changes, and stores them in the Windows Event Log. Security analysts can use this information to detect and investigate malicious activity on a system.

One way that malware can evade detection …

System Binary Proxy Execution: MMC Defense Evasion [Mitre]

Adversaries may abuse mmc.exe to proxy execution of malicious .msc files. Microsoft Management Console (MMC) is a binary that may be signed by Microsoft and is used in several ways in either its GUI or in a command prompt. MMC can be used to create, open, and save custom consoles that contain administrative tools created by Microsoft, called snap-ins. These …
