ProcEnvInjection - Remote code injection by abusing process environment strings Process Manipulating
This method allows to inject custom code into a remote process without using WriteProcessMemory
- It will use the lpEnvironment
parameter in CreateProcess
to copy the code into the target process. This technique can be used to load a DLL into a remote process, or simply execute a block of code.
The lpEnvironment
parameter in CreateProcess
allows us to specify …

Hijack Execution Flow: Executable Installer File Permissions Weakness Defense Evasion [Mitre]
Adversaries may execute their own malicious payloads by hijacking the binaries used by an installer. These processes may automatically execute specific binaries as part of their functionality or to perform other actions. If the permissions on the file system directory containing a target binary, or permissions on the binary itself, are improperly set, then the target binary may be overwritten …
Hijack Execution Flow: Services File Permissions Weakness Defense Evasion [Mitre]
Adversaries may execute their own malicious payloads by hijacking the binaries used by services. Adversaries may use flaws in the permissions of Windows services to replace the binary that is executed upon service start. These service processes may automatically execute specific binaries as part of their functionality or to perform other actions. If the permissions on the file system directory …
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 …
Process Injection: Process Doppelgänging Defense Evasion [Mitre]
Adversaries may inject malicious code into process via process doppelgänging in order to evade process-based defenses as well as possibly elevate privileges. Process doppelgänging is a method of executing arbitrary code in the address space of a separate live process.
Windows Transactional NTFS (TxF) was introduced in Vista as a method to perform safe file operations. To ensure data integrity, …
Reflective Code Loading Defense Evasion [Mitre]
Adversaries may reflectively load code into a process in order to conceal the execution of malicious payloads. Reflective loading involves allocating then executing payloads directly within the memory of the process, vice creating a thread or process backed by a file path on disk. Reflectively loaded payloads may be compiled binaries, anonymous files (only present in RAM), or just snubs …
Debug Registers, Hardware Breakpoints Anti-Debugging
Registers DR0 through DR3 contain the linear address associated with one of the four hardware breakpoint conditions. For anti-debugging, malware will check the contents of the first four debug registers to see if the hardware breakpoint has been set.
