Detecting Running Process: EnumProcess API Sandbox Evasion Anti-Monitoring Anti-Debugging
Anti-monitoring is a technique used by malware to prevent security professionals from detecting and analyzing it. One way that malware can accomplish this is by using the EnumProcess function to search for specific processes, such as ollydbg.exe or wireshark.exe, which are commonly used by security professionals to monitor and analyze running processes on a system.
By detecting these processes and …
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 …
Process Doppelgänging Process Manipulating
This technique leverages the Transactional NTFS functionality in Windows. This functionality helps maintain data integrity during an unexpected error. For example, when an application needs to write or modify a file, if an error is triggered mid-write, the data can be corrupted. To avoid this kind of behavior, an application can open the file in a transactional mode to perform …
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, …
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 …
Process Injection: Process Hollowing Defense Evasion [Mitre]
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. A …
Process Injection: Thread Execution Hijacking Defense Evasion [Mitre]
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 with …
Process Injection: Thread Local Storage Defense Evasion [Mitre]
Adversaries may inject malicious code into processes via thread local storage (TLS) callbacks in order to evade process-based defenses as well as possibly elevate privileges. TLS callback injection is a method of executing arbitrary code in the address space of a separate live process.
TLS callback injection involves manipulating pointers inside a portable executable (PE) to redirect a process to …
Process Injection: Portable Executable Injection Defense Evasion [Mitre]
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 target …
