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 …
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 …
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 …
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 …
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 …
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 …
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, …
Querying the I/O Communication Port Sandbox Evasion
VMware uses virtual I/O ports for communication between the virtual machine and the host operating system to support functionality like copy and paste between the two systems. The port can be queried and compared with a magic number VMXh to identify the use of VMware.
SIDT, Red Pill Sandbox Evasion
Red Pill is a technique used by malware to determine whether it is running on a physical machine or a virtual machine. The Red Pill technique involves executing the SIDT instruction, which retrieves the value of the Interrupt Descriptor Table Register (IDTR) and stores it in a memory location.
On a physical machine, the IDTR will contain the address …
CPUID Sandbox Evasion
The CPUID instruction is a low-level command that allows you to retrieve information about the CPU that is currently running. This instruction, which is executed at the CPU level (using the bytecode 0FA2), is available on all processors that are based on the Pentium architecture or newer.
You can use the CPUID instruction to retrieve various pieces of information …
