Execution is the method of either remotely or locally running code — malicious or otherwise — on a target computer. Execution is typically coupled with other techniques to carry out more complex tasks, like performing reconnaissance, exfiltration or credential harvesting. Execution may be ephemeral, or coupled with persistence techniques used to maintain remote access or continued code execution. See all execution payloads.

This payload is for the Key Croc, a keylogger armed with pentest tools, remote access and payloads that trigger multi-vector attacks when chosen keywords are typed. It's the ultimate key-logging pentest implant.
