300-215 Question 28
Select 3During an incident response investigation, you are tasked with identifying and classifying a suspicious file using YARA rules. Which of the following are valid characteristics of YARA rules that make them effective for malware identification and documentation?
- A
YARA rules allow the use of textual or binary patterns to match specific malware characteristics.
- B
YARA rules require the use of dynamic analysis to function effectively.
- C
YARA rules can include logical operators to combine multiple conditions for precise matching.
- D
YARA rules are written in a declarative syntax, making them easy to read and modify.
- E
YARA rules can only be used for identifying known malware signatures and cannot classify new variants.
Show answer and explanation
Correct answers: A, C, D
Explanation
YARA rules are a powerful tool for identifying, classifying, and documenting malware. They use a combination of textual or binary patterns, logical operators, and a declarative syntax to create flexible and readable rules. YARA rules do not require dynamic analysis, and they can identify both known malware signatures and new variants, making them highly versatile for forensic analysis and incident response tasks.
- A. Correct.
YARA rules use textual or binary patterns to match specific characteristics, making them effective for malware identification.
- B. Incorrect.
This is incorrect because YARA rules do not rely on dynamic analysis; they work by matching specified patterns against files statically.
- C. Correct.
YARA rules support logical operators (e.g., AND, OR) to combine conditions, allowing for precise and complex matching criteria.
- D. Correct.
YARA rules are written in a declarative syntax, making them straightforward to read, modify, and maintain for documentation purposes.
- E. Incorrect.
This is incorrect because YARA rules can also help identify new malware variants by leveraging patterns that match behaviors or characteristics common to a family of malware.
