The communication escalation path is a component of the Rules of Engagement (ROE) that provides a penetration tester with guidance on whom to contact and how to proceed in the event of an emergency or disaster during an engagement. This includes contact information for key individuals and predefined procedures to follow to ensure that any issues are addressed promptly and appropriately.

The engagement scope defines the boundaries and objectives of the test, the SLA (Service Level Agreement) outlines performance and uptime requirements, and the SOW (Statement of Work) details the tasks and deliverables. However, the communication escalation path specifically addresses communication protocols during emergencies.

Examples from penetration testing engagements highlighting the importance of communication plans: Anubis​​.

The command wmic service get name,pathname,startmode is used by penetration testers to enumerate services and their configurations, specifically looking for services with unquoted paths. If a service's path contains spaces and is not enclosed in quotes, it can be exploited by placing a malicious executable along the path, leading to privilege escalation. For example, if the service path is C:\Program Files\My Service\service.exe and is unquoted, an attacker could place a malicious Program.exe in C:\, which would then be executed with the same privileges as the service when the service starts. Identifying such services allows penetration testers to highlight potential security risks that could be exploited for privilege escalation.

 The provided output reveals a common vulnerability in Windows services known as an unquoted service path. When the service executable path is not enclosed in quotes and contains spaces, Windows may incorrectly interpret the spaces, potentially leading to the execution of unintended programs.

 Details:

Command Explanation: The command vmic service get name, pathname, displayname, startmode | findstr /i auto | findstr /i /v "C:\\Windows\\" | findstr /i /v "" filters services that are set to start automatically and are not located in the Windows directory.

Output Interpretation: The output shows a service with a path C:\Program Files\A Subfolder\B Subfolder\SomeExecutable.exe which is not quoted. If a malicious user places an executable in C:\Program.exe, C:\Program Files\A.exe, or similar, it might get executed instead.

 References: Common Windows privilege escalation vulnerabilities include unquoted service paths. This vulnerability is well-documented in security resources and penetration testing guides.

Impersonation attacks involve the penetration tester assuming the identity of a valid user to gain unauthorized access to systems or information. This method is particularly effective for gathering valid user credentials, as it can involve tactics such as phishing, social engineering, or exploiting weak authentication processes. The other options, such as Wardriving, Captive portal, and Deauthentication, are more focused on wireless network vulnerabilities and are less direct in obtaining user credentials.
