Entry Point Modification Process Manipulating

The entry point is the starting point of an executable file during execution. Some malware use techniques such as changing or relocating the real entry point to protect their code from analysis. This makes it difficult for security software to identify and detect the malware as the code is not executed in the usual way.

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 …

DLL Injection via CreateRemoteThread and LoadLibrary Process Manipulating

DLL Injection Via CreateRemoteThread and LoadLibrary is a technique used by malware to inject its code into a legitimate process. This technique is similar to hook injection, where the malware inserts a malicious DLL to be used by the system. It is one of the most common techniques used to inject malware into another process.

The malware writes the …

XOR Operation Data Obfuscation

The XOR operation is a common technique used by malware to hide data. This is because it is a simple and reversible function, meaning that the same operation can be used to both encode and decode data. In the XOR operation, a key is used to create a ciphertext, which is then used to encrypt the original data.

The …

Shortcut Hiding Antivirus/EDR Evasion

Windows shortcut can be used to store code that downloads a malicious file from the internet, or that stores the malicious file directly within the shortcut itself. This can make it difficult for antivirus software to detect the malicious application, as the file is not stored in a typical location on the computer. Additionally, the use of a shortcut can …

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 …

APC injection Process Manipulating

Malware can take advantage of Asynchronous Procedure Calls (APC) to force another thread to execute their custom code by attaching it to the APC Queue of the target thread.

Each thread has a queue of APCs which are waiting for execution upon the target thread entering alterable state.

A thread enters an alert table state if it calls …

Atom Bombing Process Manipulating

Atom Bombing is a technique that utilizes Windows Atom Tables, which provide a global storage mechanism for strings, to inject malicious code into a target process.

The technique involves storing a shellcode in an Atom Table, then using the NtQueueApcThread function to force the targeted process to access the specific Atom, causing the injection to occur. To bypass Data …

Extra Window Memory Injection Process Manipulating

Before creating a window, graphical Windows-based processes must prescribe to or register a windows class, which stipulate appearance and behavior (via windows procedures, which are functions that handle input/output of data).

Registration of new windows classes can include a request for up to 40 bytes of Extra Window Memory (EWM) to be appended to the allocated memory of each …

Propagate Process Manipulating

This technique involves modifying the internal properties of a window in order to intercept and modify or monitor the behavior of the window when it receives messages. To do this, an application creates a buffer containing shellcode and injects it into the target process.

Then, it modifies the internal structure used by the specific properties, such as UxSubclassInfo and …
