Image File Execution Options Injection
Image File Execution Options Injection, also known as IFEO Injection, is a technique used by malware to evade detection and persist on a compromised system.
The technique involves modifying the Image File Execution Options (IFEO) registry key, which is used by the Windows operating system to set debugging options for executable files. When an executable file is launched, the …
Read moreDNS 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 …
Read moreNLS Code Injection Through Registry
Dll injection through registry modification of NLS code page ID is a technique used by malware to inject a malicious DLL into a process by modifying the NLS code page ID in the registry.
There are two ways to accomplish this technique: 1. Calling the SetThreadLocale function and setting up an export function named NlsDllCodePageTranslation, where the main …
Hijack Execution Flow: Executable Installer File Permissions Weakness
![Defense Evasion [Mitre] icon](/media/2024/04/08/icons8-burglar.svg){kind=small}
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 …
Read moreHijack Execution Flow: Path Interception by Search Order Hijacking
Adversaries may execute their own malicious payloads by hijacking the search order used to load other programs. Because some programs do not call other programs using the full path, adversaries may place their own file in the directory where the calling program is located, causing the operating system to launch their malicious software at the request of the calling program.
… Read moreHijack Execution Flow: Services Registry Permissions Weakness
Adversaries may execute their own malicious payloads by hijacking the Registry entries used by services. Adversaries may use flaws in the permissions for Registry keys related to services to redirect from the originally specified executable to one that they control, in order to launch their own code when a service starts. Windows stores local service configuration information in the Registry …
Read moreHijack Execution Flow: COR_PROFILER
Adversaries may leverage the COR_PROFILER environment variable to hijack the execution flow of programs that load the .NET CLR. The COR_PROFILER is a .NET Framework feature which allows developers to specify an unmanaged (or external of .NET) profiling DLL to be loaded into each .NET process that loads the Common Language Runtime (CLR). These profilers are designed to monitor, troubleshoot, …
Read moreHijack Execution Flow: KernelCallbackTable
Adversaries may abuse the KernelCallbackTable of a process to hijack its execution flow in order to run their own payloads. The KernelCallbackTable can be found in the Process Environment Block (PEB) and is initialized to an array of graphic functions available to a GUI process once user32.dll is loaded.
An adversary may hijack the execution flow of a process …
Read moreModify Authentication Process: Reversible Encryption
An adversary may abuse Active Directory authentication encryption properties to gain access to credentials on Windows systems. The AllowReversiblePasswordEncryption property specifies whether reversible password encryption for an account is enabled or disabled. By default this property is disabled (instead storing user credentials as the output of one-way hashing functions) and should not be enabled unless legacy or other software require …
Read moreModify Authentication Process: Hybrid Identity
Adversaries may patch, modify, or otherwise backdoor cloud authentication processes that are tied to on-premises user identities in order to bypass typical authentication mechanisms, access credentials, and enable persistent access to accounts.
Many organizations maintain hybrid user and device identities that are shared between on-premises and cloud-based environments. These can be maintained in a number of ways. For example, …
