Dynamic analysis is the specific method WildFire uses to execute, or "detonate," unknown files in a secure, custom-built virtual sandbox environment. This process allows WildFire to observe the submission's true behavior and malicious activities as they would occur on a real endpoint. It monitors for actions such as creating or modifying files, changing registry keys, and initiating network connections. The detailed report of these observed behaviors provides visibility into the submission's real-world effects, which is the core of the question. This method is fundamental to identifying zero-day malware that static analysis might miss.

B. Static analysis: This method examines a file's properties and code without executing it. It cannot detonate a file or observe its real-world behavior.

C. Intelligent Run-time Memory Analysis: This is a specific technique used during dynamic analysis to detect threats in memory, not the overarching method of detonation itself.

D. Machine learning (ML): ML is a decision-making engine that analyzes the data collected from both static and dynamic analysis to determine if a file is malicious; it is not the detonation process.

1. Palo Alto Networks. (2023). WildFire Administrator's Guide PAN-OS 11.0. In the "WildFire Analysis" section

it states: "To determine if the sample is malicious

WildFire uses a custom-built

evasion-resistant virtual environment to safely execute and observe unknown files... This process is called dynamic analysis."

2. Palo Alto Networks. (2023). WildFire Cloud-Delivered Security Services Datasheet. This document explains

"WildFire combines the benefits of static and dynamic analysis... Dynamic analysis detonates unknown files in a custom-built

evasion-resistant virtual environment to identify novel malware."

3. Palo Alto Networks. (2021). What is WildFire?. The official product page describes the process: "WildFire performs in-depth analysis by executing the submission in a sandbox environment to observe its real-world behavior. This is known as dynamic analysis." This source explicitly links detonation in a sandbox to the term "dynamic analysis."
