Native API

Adversaries may interact with the native OS application programming interface (API) to execute behaviors. Native APIs provide a controlled means of calling low-level OS services within the kernel, such as those involving hardware/devices, memory, and processes.[1][2] These native APIs are leveraged by the OS during system boot (when other system components are not yet initialized) as well as carrying out tasks and requests during routine operations.

Adversaries may abuse these OS API functions as a means of executing behaviors. Similar to Command and Scripting Interpreter, the native API and its hierarchy of interfaces provide mechanisms to interact with and utilize various components of a victimized system.

Native API functions (such as NtCreateProcess) may be directed invoked via system calls / syscalls, but these features are also often exposed to user-mode applications via interfaces and libraries.[3][4][5] For example, functions such as the Windows API CreateProcess() or GNU fork() will allow programs and scripts to start other processes.[6][7] This may allow API callers to execute a binary, run a CLI command, load modules, etc. as thousands of similar API functions exist for various system operations.[8][9][10]

Higher level software frameworks, such as Microsoft .NET and macOS Cocoa, are also available to interact with native APIs. These frameworks typically provide language wrappers/abstractions to API functionalities and are designed for ease-of-use/portability of code.[11][12][13][14]

Adversaries may use assembly to directly or in-directly invoke syscalls in an attempt to subvert defensive sensors and detection signatures such as user mode API-hooks.[15] Adversaries may also attempt to tamper with sensors and defensive tools associated with API monitoring, such as unhooking monitored functions via Disable or Modify Tools.

Mitigations

ID Mitigation Description
M1040 Behavior Prevention on Endpoint

On Windows 10, enable Attack Surface Reduction (ASR) rules to prevent Office VBA macros from calling Win32 APIs. [213]
M1038 Execution Prevention

Identify and block potentially malicious software executed that may be executed through this technique by using application control [214] tools, like Windows Defender Application Control[215], AppLocker, [216] [217] or Software Restriction Policies [218] where appropriate. [219]

Detection

ID Data Source Data Component Detects
DS0011 Module Module Load

Monitor DLL/PE file events, specifically creation of these binary files as well as the loading of DLLs into processes. Utilization of the Windows APIs may involve processes loading/accessing system DLLs associated with providing called functions (ex: ntdll.dll, kernel32.dll, advapi32.dll, user32.dll, and gdi32.dll). Monitoring for DLL loads, especially to abnormal/unusual or potentially malicious processes, may indicate abuse of the Windows API. Though noisy, this data can be combined with other indicators to identify adversary activity.

Analytic 1 - Look for unusual or abnormal DLL loads, processes loading DLLs not typically associated with them

sourcetype=Sysmon EventCode=7| stats count by module_name process_name user| where module_name IN ("ntdll.dll", "kernel32.dll", "advapi32.dll", "user32.dll", "gdi32.dll")

DS0009 Process OS API Execution

Monitoring API calls may generate a significant amount of data and may not be useful for defense unless collected under specific circumstances, since benign use of API functions are common and may be difficult to distinguish from malicious behavior. Correlation of other events with behavior surrounding API function calls using API monitoring will provide additional context to an event that may assist in determining if it is due to malicious behavior. Correlation of activity by process lineage by process ID may be sufficient.
