Dirty Vanity
Dirty Vanity is a process injection technique that exploits the Windows forking (process reflection and snapshotting) feature to inject code into a new process.
It uses the RtlCreateProcessReflection or NtCreateProcess[Ex] primitives, along with the PROCESS_VM_OPERATION, PROCESS_CREATE_THREAD, and PROCESS_DUP_HANDLE flags to reflect and execute code in a new process.
The technique also makes use of various methods, …

![Defense Evasion [Mitre] icon](/media/2024/04/08/icons8-burglar.svg){kind=small}
Adversaries may attempt to hide process command-line arguments by overwriting process memory. Process command-line arguments are stored in the process environment block (PEB), a data structure used by Windows to store various information about/used by a process. The PEB includes the process command-line arguments that are referenced when executing the process. When a process is created, defensive tools/sensors that monitor …
Read moreProcess Injection: Dynamic-link Library Injection
Adversaries may inject dynamic-link libraries (DLLs) into processes in order to evade process-based defenses as well as possibly elevate privileges. DLL injection is a method of executing arbitrary code in the address space of a separate live process.
DLL injection is commonly performed by writing the path to a DLL in the virtual address space of the target process …
Read moreProcess Injection: Portable Executable Injection
Adversaries may inject portable executables (PE) into processes in order to evade process-based defenses as well as possibly elevate privileges. PE injection is a method of executing arbitrary code in the address space of a separate live process.
PE injection is commonly performed by copying code (perhaps without a file on disk) into the virtual address space of the …
Read moreProcess Injection: Thread Execution Hijacking
Adversaries may inject malicious code into hijacked processes in order to evade process-based defenses as well as possibly elevate privileges. Thread Execution Hijacking is a method of executing arbitrary code in the address space of a separate live process.
Thread Execution Hijacking is commonly performed by suspending an existing process then unmapping/hollowing its memory, which can then be replaced …
Read moreProcess Injection: Process Hollowing
Adversaries may inject malicious code into suspended and hollowed processes in order to evade process-based defenses. Process hollowing is a method of executing arbitrary code in the address space of a separate live process.
Process hollowing is commonly performed by creating a process in a suspended state then unmapping/hollowing its memory, which can then be replaced with malicious code. …
Read moreProcess Injection: ListPlanting
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 …
Read moreProcess Hollowing, RunPE
Process hollowing is a technique used by malware to evade detection by injecting malicious code into a legitimate process. This technique involves creating a new instance of a legitimate process and replacing its original code with the malicious payload.
The process is the following:
CreateProcess: in a suspended mode with the CreationFlag at 0x0000 0004.…
PE Injection
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 …
DNS API Injection
DNS API injection is a technique used by malware to evade detection by intercepting and modifying DNS (Domain Name System) requests made by a host system. The technique involves injecting code into the DNS API (Application Programming Interface) of the host system, which is a set of functions and protocols that allow communication with the DNS service. By injecting code …
