    Correct Answer: A

user009Option: A

The correct answer is A. The first command creates a backdoor shell as a service. It is being started on TCP 2222 using cmd.exe. The second command verifies the service is created and its status. Here's why the other answers are incorrect: B. The first part of the answer is correct in that it creates a backdoor shell as a service. However, it incorrectly states that it is being started on UDP 2222. The command provided specifies the "-p 2222" flag, which indicates a TCP port rather than a UDP port. C. This answer is incorrect because it misinterprets the purpose of the ncservice. It is not designed to stop any instance of nc.exe. Instead, it creates a backdoor shell as a service, as stated in answer A. D. This answer has the commands' purposes switched. The first command is not verifying the service's status; it is creating the backdoor shell. The second command is incomplete and does not provide enough information to determine its purpose.

A is the correct answer. A malicious PDF or excel macro document is a classic client side attack. Those don't attack listening services they attack applications which have received something through the network (e.g. malicious document via e-mail...)
