NEW QUESTION # 36
Within the MITRE-Based Falcon Detections Framework, what is the correct way to interpret Keep Access > Persistence > Create Account?
- A. An adversary is trying to keep access through persistence using browser extensions
- B. An adversary is trying to keep access through persistence by creating an account
- C. adversary is trying to keep access through persistence using application skimming
- D. An adversary is trying to keep access through persistence using external remote services
Answer: B
Explanation:
Explanation
According to the [CrowdStrike website], the MITRE-Based Falcon Detections Framework is a way of categorizing and describing detections based on the MITRE ATT&CK knowledge base ofadversary behaviors and techniques. The framework uses three levels of granularity: category, tactic, and technique. The category is the highest level and represents the main objective of an adversary, such as initial access, execution, credential access, etc. The tactic is the second level and represents the sub-objective of an adversary within a category, such as persistence, privilege escalation, defense evasion, etc. The technique is the lowest level and represents the specific way an adversary can achieve a tactic, such as create account, modify registry, obfuscated files or information, etc. Therefore, the correct way to interpret Keep Access > Persistence > Create Account is that an adversary is trying to keep access through persistence by creating an account.
