What technique does WildFire NOT perform?

WildFire is a cloud-based malware analysis service provided by Palo Alto Networks that leverages various techniques to detect and analyze malicious files. The feature that it does not perform is DEP (Data Execution Prevention).

WildFire primarily relies on dynamic analysis to execute and observe the behavior of files in a secure environment. It runs files in a virtualized environment to determine if they exhibit malicious activity. Additionally, it uses machine learning to enhance detection capabilities by analyzing patterns in the data gathered from previous analyses. Dynamic unpacking is another technique used by WildFire, which involves extracting packed malicious files so that they can be analyzed accurately.

DEP, on the other hand, is a security feature found in operating systems that prevents code from being executed in certain regions of memory that are not meant for execution. It is not a technique employed by WildFire itself in its malware analysis processes, making it the correct answer in this context.
