What capability describes how PsExec channels the command's Standard Input and Standard Output between attacker and target?

• A. It runs the command entirely locally with no network
• B. It channels the Standard Input/Output back and forth between the attacker and the command, displaying results inline
• C. It duplicates the output to a log file only
• D. It uses a GUI to display output

Answer: (B)

PsExec sets up a remote service on the target and bridges the command’s input and output streams across the network. The key capability is the bidirectional forwarding of Standard Input and Standard Output, so you can type commands and see results immediately. This interactive I/O channel makes PsExec function like a remote shell rather than simply running a task and saving output to a file. It’s not about local execution, logging to a file, or a GUI display—the emphasis is real-time, two-way communication between attacker and remote process.
