Single Answer
0Jared is responsible for network security at his company. He has discovered behavior on one computer that certainly appears to be a virus. He has even identified a file he thinks might be the virus. However, using three separate antivirus programs, he finds that none can detect the file. Which of the following is most likely to be occurring?
Answer Options
A
The computer has a RAT.
B
The computer has a zero-day exploit.
C
The computer has a worm.
D
The computer has a rootkit.
Correct Answer: B
Explanation
Zero-day exploits are new, and they are not in the virus definitions for the antivirus (AV) programs. This makes them difficult to detect, except by their behavior. Remote-access Trojans (RATs), worms, and rootkits are more likely to be detected by AV programs.
