What is WaitForMultipleObjects?
The WaitForMultipleObjects function can specify handles of any of the following object types in the lpHandles array: Change notification. Console input. Event. Memory resource notification.
How does WaitForSingleObject work?
The WaitForSingleObject function checks the current state of the specified object. If the object’s state is nonsignaled, the calling thread enters the wait state until the object is signaled or the time-out interval elapses. The function modifies the state of some types of synchronization objects.
What is CreateRemoteThread?
The CreateRemoteThread function causes a new thread of execution to begin in the address space of the specified process. The thread has access to all objects that the process opens. Prior to Windows 8, Terminal Services isolates each terminal session by design.
What is CreateEventW?
CreateEventW function (synchapi.h) – Win32 apps Creates or opens a named or unnamed event object.
What is Peeknamedpipe?
A pointer to a variable that receives the number of bytes read from the pipe. This parameter can be NULL if no data is to be read. [out, optional] lpTotalBytesAvail. A pointer to a variable that receives the total number of bytes available to be read from the pipe. This parameter can be NULL if no data is to be read.
What is duplicate handle?
The duplicate handle refers to the same object as the original handle. Therefore, any changes to the object are reflected through both handles. For example, if you duplicate a file handle, the current file position is always the same for both handles.
What is an APC injection?
APC injection is a method of executing arbitrary code in the address space of a separate live process. APC injection is commonly performed by attaching malicious code to the APC Queue of a process’s thread. Queued APC functions are executed when the thread enters an alterable state.
What is pipe window?
What is a Pipe? Like most IPC mechanisms, pipes help facilitate communication between two applications and or processes using shared memory . This shared memory is treated as a file object in the Windows operating system.
Are Named Pipes secure?
If you specify NULL, the named pipe gets a default security descriptor. The ACLs in the default security descriptor for a named pipe grant full control to the LocalSystem account, administrators, and the creator owner. They also grant read access to members of the Everyone group and the anonymous account.
What is Hmodule?
HMODULE. A handle to a module. The is the base address of the module in memory. HMODULE and HINSTANCE are the same in current versions of Windows, but represented different things in 16-bit Windows.
How do you get thread handles?
If you have a thread identifier, you can get the thread handle by calling the OpenThread function. OpenThread enables you to specify the handle’s access rights and whether it can be inherited.
What is an APC kernel?
In a kernel APC attack, the attacker gives a legitimate program’s place in line to the attacker’s code. The crux of what makes this attack technique so important is how the technique uses this level of control to have legitimate programs run illegitimate commands.
What is pipe protocol?
Protocol pipelining is a technique in which multiple requests are written out to a single socket without waiting for the corresponding responses. Pipelining can be used in various application layer network protocols, like HTTP/1.1, SMTP and FTP.
What is Npipe?
A named pipe is a one-way or duplex pipe that provides communication between the pipe server and some pipe clients. A pipe is a section of memory that is used for interprocess communication.
