Question

While investigating a malware infection, Lauren discovers that the hosts file for the system she is reviewing contains multiple entries, as shown here: Why would the malware make this change?

A. To redirect to known sites
B. To prevent antivirus updates
C. To prevent other attackers from compromising the system
D. To enable remote access to the system

Answer 1

The malware modifies the hosts file to redirect user traffic to malicious servers, often for the purpose of deceiving users. This technique is used to trick users into providing sensitive information or downloading more malware, rather than specifically enabling remote access.

Step-by-step explanation:

When investigating a malware infection on a system, one might discover that the hosts file contains multiple entries. The reason a malware program would make changes to the hosts file is often to redirect traffic from the infected system to different servers controlled by hackers. This is done, not specifically to enable remote access, but to intercept or manipulate the user's network traffic.

Hackers use this technique to redirect users away from legitimate sites to fraudulent ones, where they can be tricked into downloading further malware or providing sensitive information. Altering the hosts file is a common method because it can be done quickly and can target specific websites that the user may trust.

Understanding the intent behind malware modifications to system files is critical in cybersecurity. This kind of change is malicious and is designed to gain unauthorized access to data or to trick users into performing actions that compromise security. Through the alteration of the hosts file, hackers can carry out a variety of deceptive and harmful activities, reinforcing the need for robust cybersecurity measures.
