MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.80). The install commands in Step 1 fetch and install remote packages (e.g., https://packages.wazuh.com/4.x/windows/wazuh-agent-4.9.0-1.msi and the APT repo at https://packages.wazuh.com/4.x/apt/ plus the GPG key https://packages.wazuh.com/key/GPG-KEY-WAZUH) during runtime to provide required agent code which will be executed on hosts, so these URLs constitute runtime external dependencies that deliver and execute remote code.

MEDIUM W013: Attempt to modify system services in skill instructions.

• Attempt to modify system services in skill instructions detected (high risk: 1.00). The skill contains explicit, privileged system-modifying instructions (adding APT sources and GPG keys, writing to /etc and /var/ossec, running apt-get/msiexec, enabling systemd services, and configuring active-response actions that block IPs or disable accounts), which require administrative access and change the machine's state.
