PE Injection Process Manipulating

Instead of passing the address of the LoadLibrary, malware can copy its malicious code into an existing open process and force it to execute (either via a small shellcode, or by calling CreateRemoteThread).

One advantage of PE injection over the LoadLibrary technique is that the malware does not have to drop a malicious DLL on the disk. The …

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 …

Ctrl+Inject Process Manipulating

The "Control Signal Handler Callback" technique involves injecting malicious code into a process by using a callback function for control signal handlers. When a control signal, such as Ctrl+C, is received by a process, the system creates a new thread to execute a function to handle the signal. This thread is typically created by the legitimate process "csrss.exe" in 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 …

API Hammering Sandbox Evasion

API hammering is a technique used to delay sandbox analysis and thus avoid malware capability analysis reporting. This technique consists of calling a large amount of benign APIs like "printf" in a loop.

RDTSCP Sandbox Evasion

Newer processors support a new instruction called RDTSCP which does the exact same thing as RDTSC, except that it does so serializing (meaning it waits for all instructions to execute before reading the counter. and that the possible reordering of the execution of the instructions is won that does not happen).

This instruction can be used to calculate the …

GetForegroundWindow Sandbox Evasion

This technique uses the GetForegroundWindow and Sleep APIs to attempt to evade sandboxes. Many sandboxes do not alter the foreground window like a user would in a normal desktop environment.

It accomplishes this by making a call to GetForegroundWindow, which returns a handle to the current window. Then the malware sample will sleep for a short time, followed by …

Treepoline Process Manipulating

Tree-view controls are a type of user interface element that is used to display hierarchical data in a graphical user interface (GUI). They are commonly used in Windows applications and allow users to navigate and explore complex data structures.

To display its content, a tree-view control must sort the items it shows. The sorting routine for a tree-view control …

Process Ghosting Process Manipulating

Process Ghosting is a technique used to bypass detection by manipulating the executable image when a process is loaded.

Windows attempts to prevent mapped executables from being modified. Once a file is mapped into an image section, attempts to open it with FILE_WRITE_DATA (to modify it) will fail with ERROR_SHARING_VIOLATION. Deletion attempts via FILE_DELETE_ON_CLOSE/FILE_FLAG_DELETE_ON_CLOSE fail with …
