Attack Path
Attack Path in Security Assessments
Attack Path Definition: An attack path is the sequence of steps or actions that an attacker could take to compromise a target system or network. It typically involves identifying and exploiting vulnerabilities in various components of the target environment, such as servers, applications, network devices, and user accounts.
Developing Attack Paths
Developing attack paths involves systematic planning and execution to simulate potential attack scenarios and understand how an adversary could breach the security of an organization. Here are steps and methodologies commonly followed:
Reconnaissance and Information Gathering:
Objective: Identify potential entry points and targets within the organization's network and systems.
Methods: Use tools like Nmap, Recon-ng, or OSINT techniques to gather information about network infrastructure, IP addresses, domain names, employee information, and more.
Vulnerability Assessment:
Objective: Identify weaknesses and vulnerabilities within the identified targets.
Methods: Utilize tools such as Nessus, OpenVAS, or manual techniques to scan for known vulnerabilities in systems, applications, and services.
Exploitation and Initial Access:
Objective: Exploit identified vulnerabilities to gain initial access to the target systems or network segments.
Methods: Use tools like Metasploit, SQLmap, or custom scripts to exploit vulnerabilities found during the assessment phase.
Lateral Movement:
Objective: Move deeper into the network, escalating privileges and accessing sensitive information.
Methods: Exploit weaknesses in network segmentation, weak credentials, or misconfigured access controls to move laterally within the network.
Persistence and Evasion:
Objective: Maintain access to compromised systems and evade detection by security controls.
Methods: Install backdoors, rootkits, or modify system configurations to maintain access. Use techniques to evade detection by IDS/IPS, antivirus software, or endpoint detection and response (EDR) systems.
Exfiltration or Impact:
Objective: Achieve the ultimate goal of the attack, such as data exfiltration, disruption of services, or other malicious activities.
Methods: Transfer sensitive data out of the organization, execute ransomware attacks, or perform actions that align with the attacker's objectives.
Methodologies to Follow
Several methodologies guide the development and execution of attack paths during security assessments:
Penetration Testing Frameworks: Frameworks like PTES (Penetration Testing Execution Standard) provide structured guidelines for conducting penetration tests, including reconnaissance, vulnerability analysis, exploitation, and reporting.
MITRE ATT&CK Framework: This framework categorizes attacker techniques and tactics, helping assessors simulate realistic attack paths based on real-world scenarios.
Red Team Operations: Red teaming involves simulating realistic attacks to evaluate an organization's readiness and response capabilities. It focuses on developing sophisticated attack paths and assessing defensive strategies.
Kill Chain Methodology: Derived from military strategies, the kill chain model breaks down attacks into stages (e.g., reconnaissance, weaponization, delivery, exploitation, installation, command and control, and actions on objectives), aiding in understanding and defending against attacks.
Usage and Application
Scenario-Based Testing: Develop attack paths based on likely scenarios specific to the organization's industry, infrastructure, and threat landscape.
Continuous Assessment: Attack paths evolve as systems and defenses change. Regularly reassess and update attack paths to reflect current vulnerabilities and security controls.
