You want to connect to your friend's computer and run a Trojan on it. Which of the following tools will you use to accomplish the task?

PSExec, part of the Microsoft Sysinternals suite, establishes an authenticated remote session and executes any specified program on the target computer over SMB. Attackers abuse it in post-exploitation scenarios because it requires no pre-installed agent and can run arbitrary executables - including Trojans - with the privileges of the authenticated user. It is one of the most commonly abused legitimate tools in lateral movement and remote malware deployment.

Hk.exe is a local Windows privilege escalation exploit tool, not a remote execution utility, so it cannot deploy software to another computer.

Remoxec is not a widely recognized or documented remote execution utility relevant to this attack scenario.

GetAdmin.exe is a local privilege escalation tool that grants administrator rights on the local machine, not a tool for executing code remotely on another system.
