T1211 Exploitation for Defense Evasion Mappings

Adversaries may exploit a system or application vulnerability to bypass security features. Exploitation of a software vulnerability occurs when an adversary takes advantage of a programming error in a program, service, or within the operating system software or kernel itself to execute adversary-controlled code. Vulnerabilities may exist in defensive security software that can be used to disable or circumvent them.

Adversaries may have prior knowledge through reconnaissance that security software exists within an environment or they may perform checks during or shortly after the system is compromised for Security Software Discovery. The security software will likely be targeted directly for exploitation. There are examples of antivirus software being targeted by persistent threat groups to avoid detection.

Comments
This control's Fileless Attack Detection identifies shellcode executing within process memory, including shellcode executed as a payload in the exploitation of a software vulnerability. Detection is periodic at an unknown rate. The following alerts may be generated: "Fileless attack technique detected", "Fileless attack behavior detected", "Fileless attack toolkit detected", "Suspicious SVCHOST process executed".

integrated_vulnerability_scanner_powered_by_qualys Integrated Vulnerability Scanner Powered by Qualys technique_scores T1211 Exploitation for Defense Evasion
Comments
Once this control is deployed, it can detect known vulnerabilities in Windows and various Linux endpoints. This information can be used to patch, isolate, or remove vulnerable software and machines. This control does not directly protect against exploitation and it is not effective against zero day attacks, vulnerabilities with no available patch, and software that may not be analyzed by the scanner. As a result, the score is capped at Partial.
