Question
A security analyst has identified a new malware file that has impacted the organization. The malware is polymorphic and has built-in conditional triggers that require a connection to the internet. The CPU has an idle process of at least 70%.
Which of the following best describes how the security analyst can effectively review the malware without compromising the organization’s network?
A. Utilize an RDP session on an unused workstation to evaluate the malware.
B. Disconnect and utilize an existing infected asset off the network.
C. Create a virtual host for testing on the security analyst workstation.
D. Subscribe to an online service to create a sandbox environment.
Answer
D. Subscribe to an online service to create a sandbox environment.
Explanation
A sandbox environment is a secure, isolated virtual space where untrusted programs can be run safely. It prevents the malware from interacting with the host system or network, thereby protecting the organization’s network from potential harm. This is particularly important when dealing with polymorphic malware, which can change its code to evade detection, and malware that requires an internet connection, as it may communicate with an external server or download additional malicious components.
Option A, utilizing an RDP session on an unused workstation, is not ideal because if the malware is designed to spread over a network, it could potentially infect other systems. Option B, disconnecting and utilizing an existing infected asset off the network, could risk further infection if the malware has any dormant capabilities that are triggered when certain conditions are met. Option C, creating a virtual host for testing on the security analyst’s workstation, could put the analyst’s workstation at risk, especially if the malware manages to escape the virtual environment.
