Process Injection: ListPlanting Defense Evasion [Mitre]

Adversaries may abuse list-view controls to inject malicious code into hijacked processes in order to evade process-based defenses as well as possibly elevate privileges. ListPlanting is a method of executing arbitrary code in the address space of a separate live process. Code executed via ListPlanting may also evade detection from security products since the execution is masked under a legitimate …

Hijack Execution Flow: KernelCallbackTable Defense Evasion [Mitre]

Adversaries may abuse the KernelCallbackTable of a process to hijack its execution flow in order to run their own payloads. The KernelCallbackTable can be found in the Process Environment Block (PEB) and is initialized to an array of graphic functions available to a GUI process once user32.dll is loaded.

An adversary may hijack the execution flow of a process using …

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, …

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 …

OLEUM 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 …

CLIPBRDWNDCLASS Process Manipulating

CLIPBRDWNDCLASS is a window class that is registered by the Object Linking & Embedding (OLE) library (ole32.dll) to handle clipboard data. When a window of this class is created, it is assigned a number of window properties that store the addresses of various interfaces that are used to process clipboard data. These interfaces include the ClipboardDataObjectInterface, ClipboardRootDataObjectInterface, and …

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 …

Detecting Window with FindWindow API Anti-Monitoring Anti-Debugging

The FindWindowA / FindWindowW function can be used to search for windows by name or class.

It is also possible to use EnumWindows API in conjunction with GetWindowTextLength and GetWindowText to locate a piece of string that could reveal the presence of a known debugger.

Some Known Debuggers

ImmunityDebugger
OllyDbg
IDA
x64dbg / x32dbg
WinDbg

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 …
