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 CC32SubclassInfo, …

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 Execution …

WordWarping Process Manipulating

Edit controls are a type of user interface element that allows a user to enter and edit text in a graphical user interface (GUI). They are commonly used in Windows applications and can be embedded directly into a GUI or subclassed as a separate window. Edit controls can be set to display text in multiline mode, in which case they …

EditWordBreakProc Process Manipulating

Edit controls, including Rich Edit controls, are a common type of Windows control found in many applications. They can be embedded directly in the application or as subclassed windows.

When these controls display text in multiline mode, they use a callback function called EditWordBreakProc. This function is called every time the control needs to do something related to word …

Process Injection: Extra Window Memory Injection Defense Evasion [Mitre]

Adversaries may inject malicious code into process via Extra Window Memory (EWM) in order to evade process-based defenses as well as possibly elevate privileges. EWM injection is a method of executing arbitrary code in the address space of a separate live process.

Before creating a window, graphical Windows-based processes must prescribe to or register a windows class, which stipulate appearance …

Hell's Gate Antivirus/EDR Evasion

The Hell's Gate technique refers to a specific method used by malware authors to make their software more difficult to detect and analyze. The technique involves the use of a custom native API resolver to resolve Windows API functions at runtime dynamically.

By using Hell's Gate, malware can avoid referencing the Windows API functions directly in the Import Address Table …

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 instance …

Process Doppelgänging Process Manipulating

This technique leverages the Transactional NTFS functionality in Windows. This functionality helps maintain data integrity during an unexpected error. For example, when an application needs to write or modify a file, if an error is triggered mid-write, the data can be corrupted. To avoid this kind of behavior, an application can open the file in a transactional mode to perform …

Modify Authentication Process: Multi-Factor Authentication Defense Evasion [Mitre]

Adversaries may disable or modify multi-factor authentication (MFA) mechanisms to enable persistent access to compromised accounts.

Once adversaries have gained access to a network by either compromising an account lacking MFA or by employing an MFA bypass method such as Multi-Factor Authentication Request Generation, adversaries may leverage their access to modify or completely disable MFA defenses. This can be accomplished …
