M1050 Exploit Protection

Deploy capabilities that detect, block, and mitigate conditions indicative of software exploits. These capabilities aim to prevent exploitation by addressing vulnerabilities, monitoring anomalous behaviors, and applying exploit-mitigation techniques to harden systems and software.

Operating System Exploit Protections:

  • Use Case: Enable built-in exploit protection features provided by modern operating systems, such as Microsoft’s Exploit Protection, which includes techniques like Data Execution Prevention (DEP), Address Space Layout Randomization (ASLR), and Control Flow Guard (CFG).
  • Implementation: Enforce DEP for all programs and enable ASLR to randomize memory addresses used by system and application processes. Windows: Configure Exploit Protection through the Windows Security app or deploy settings via Group Policy. ExploitProtectionExportSettings.exe -path "exploit_settings.xml" Linux: Use Kernel-level hardening features like SELinux, AppArmor, or GRSEC to enforce memory protections and prevent exploits.

Third-Party Endpoint Security:

  • Use Case: Use endpoint protection tools with built-in exploit protection, such as enhanced memory protection, behavior monitoring, and real-time exploit detection.
  • Implementation: Deploy tools to detect and block exploitation attempts targeting unpatched software.

Virtual Patching: - Use Case: Use tools to implement virtual patches that mitigate vulnerabilities in applications or operating systems until official patches are applied. - Implementation: Use Intrusion Prevention System (IPS) to block exploitation attempts on known vulnerabilities in outdated applications.

Hardening Application Configurations:

  • Use Case: Disable risky application features that can be exploited, such as macros in Microsoft Office or JScript in Internet Explorer.
  • Implementation: Configure Microsoft Office Group Policies to disable execution of macros in downloaded files.

Techniques Addressed by Mitigation

Domain ID Name Use
enterprise T1189 Drive-by Compromise Security applications that look for behavior used during exploitation such as Windows Defender Exploit Guard (WDEG) and the Enhanced Mitigation Experience Toolkit (EMET) can be used to mitigate some exploitation behavior.1 Control flow integrity checking is another way to potentially identify and stop a software exploit from occurring.2 Many of these protections depend on the architecture and target application binary for compatibility.
enterprise T1190 Exploit Public-Facing Application Web Application Firewalls may be used to limit exposure of applications to prevent exploit traffic from reaching the application.
enterprise T1203 Exploitation for Client Execution Security applications that look for behavior used during exploitation such as Windows Defender Exploit Guard (WDEG) and the Enhanced Mitigation Experience Toolkit (EMET) can be used to mitigate some exploitation behavior. 1 Control flow integrity checking is another way to potentially identify and stop a software exploit from occurring. 2 Many of these protections depend on the architecture and target application binary for compatibility.
enterprise T1212 Exploitation for Credential Access Security applications that look for behavior used during exploitation such as Windows Defender Exploit Guard (WDEG) and the Enhanced Mitigation Experience Toolkit (EMET) can be used to mitigate some exploitation behavior.1 Control flow integrity checking is another way to potentially identify and stop a software exploit from occurring.2 Many of these protections depend on the architecture and target application binary for compatibility and may not work for software targeted for defense evasion.
enterprise T1211 Exploitation for Defense Evasion Security applications that look for behavior used during exploitation such as Windows Defender Exploit Guard (WDEG) and the Enhanced Mitigation Experience Toolkit (EMET) can be used to mitigate some exploitation behavior. 1 Control flow integrity checking is another way to potentially identify and stop a software exploit from occurring. 2 Many of these protections depend on the architecture and target application binary for compatibility and may not work for software targeted for defense evasion.
enterprise T1068 Exploitation for Privilege Escalation Security applications that look for behavior used during exploitation such as Windows Defender Exploit Guard (WDEG) and the Enhanced Mitigation Experience Toolkit (EMET) can be used to mitigate some exploitation behavior. 1 Control flow integrity checking is another way to potentially identify and stop a software exploit from occurring. 2 Many of these protections depend on the architecture and target application binary for compatibility and may not work for software components targeted for privilege escalation.
enterprise T1210 Exploitation of Remote Services Security applications that look for behavior used during exploitation such as Windows Defender Exploit Guard (WDEG) and the Enhanced Mitigation Experience Toolkit (EMET) can be used to mitigate some exploitation behavior. 1 Control flow integrity checking is another way to potentially identify and stop a software exploit from occurring. 2 Many of these protections depend on the architecture and target application binary for compatibility and may not work for all software or services targeted.
enterprise T1218 System Binary Proxy Execution Microsoft’s Enhanced Mitigation Experience Toolkit (EMET) Attack Surface Reduction (ASR) feature can be used to block methods of using using trusted binaries to bypass application control.
enterprise T1218.010 Regsvr32 Microsoft’s Enhanced Mitigation Experience Toolkit (EMET) Attack Surface Reduction (ASR) feature can be used to block regsvr32.exe from being used to bypass application control. 7 Identify and block potentially malicious software executed through regsvr32 functionality by using application control 3 tools, like Windows Defender Application Control5, AppLocker, 9 8 or Software Restriction Policies 4 where appropriate. 6
enterprise T1218.011 Rundll32 Microsoft’s Enhanced Mitigation Experience Toolkit (EMET) Attack Surface Reduction (ASR) feature can be used to block methods of using rundll32.exe to bypass application control.
enterprise T1218.015 Electron Applications Microsoft’s Enhanced Mitigation Experience Toolkit (EMET) Attack Surface Reduction (ASR) feature can be used to block methods of using trusted binaries to bypass application control.
Ensure that Electron is updated to the latest version and critical vulnerabilities (such as nodeIntegration bypasses) are patched and cannot be exploited.
enterprise T1080 Taint Shared Content Use utilities that detect or mitigate common features used in exploitation, such as the Microsoft Enhanced Mitigation Experience Toolkit (EMET).
