300-215 Question 26
Select 3During a malware investigation, you are tasked with identifying suspicious files using YARA rules. Which of the following characteristics of YARA rules makes them effective for malware identification and classification?
- A
YARA rules use a pattern-matching approach based on text or binary strings.
- B
YARA rules can classify files based on behavioral analysis without needing pre-defined conditions.
- C
YARA rules allow the use of logical operators to combine multiple conditions.
- D
YARA rules are designed to execute malware samples in a sandbox for dynamic analysis.
- E
YARA rules provide a flexible framework for documenting malware characteristics.
Show answer and explanation
Correct answers: A, C, E
Explanation
YARA rules are a powerful tool for malware identification and classification. They use pattern matching and logical operators to define static conditions that files must meet. Additionally, they provide a framework for documenting malware characteristics. However, YARA rules are not designed for behavioral or dynamic analysis, as they do not execute files or analyze runtime behavior.
- A. Correct.
Correct: YARA rules use pattern matching to detect specific strings or byte sequences, making them highly effective for malware identification.
- B. Incorrect.
Incorrect: YARA rules do not analyze behavior directly; they rely on pre-defined conditions like patterns, strings, and logical expressions.
- C. Correct.
Correct: Logical operators (e.g., AND, OR) in YARA rules enable combining multiple conditions for more precise detection.
- D. Incorrect.
Incorrect: YARA rules do not execute malware in a sandbox; they are used for static analysis by matching patterns in files.
- E. Correct.
Correct: YARA rules can document characteristics like strings, conditions, and metadata, making them useful for tracking malware attributes.
