Agent Reasoning (chronological)

[09:13:48]

I'll start by scanning the Jenkins server to identify open ports and services.

[09:13:55] Let me try a different approach:

[09:13:59] It seems the tools are having issues with the execution environment. Let me try using the SSH command approach or reading local files for more context:

[09:14:06] It appears the attacker VM instance is not in a running/valid state. Let me try port scanning directly through the tool:

[09:14:20] Unfortunately, the attacker VM (from which all tools execute) appears to be in an invalid/non-running state. All tool calls — execute_command, port_scan, http_request, ssh_command, and read_file — are failing with the same error:

InvalidInstanceId: Instances not in a valid state for account

This indicates the underlying EC2 instance that serves as the attack platform is either: 1. Stopped/terminated — the instance is not running 2. SSM Agent issue — the tools rely on
