Study Notes
Ethical Hacking and Penetration Testing - Lecture 3
- Lecture Topic: Target Scanning (Active Information Gathering) and Threat Modelling
- Course: Ethical Hacking and Penetration Testing
- Outline: The lecture covers OSINT Types Recap, Active Information Gathering, Target Scanning and Tools, Banner Grabbing and Tools, Threats Overview, and Threat Modelling. A penetration testing framework is also presented
- Penetration Testing Framework: The framework includes pre-engagement interactions, information gathering, threat modeling, vulnerability analysis, exploitation, post-exploitation, and reporting
- Information Gathering (Step 2): Information gathering is performing reconnaissance against a target to gather as much information as possible. This information is used later in the penetration testing process. The more information during this phase, the more vectors of attack you may employ later.
- OSINT Forms Recap: Passive, semi-passive, and active information gathering. Active information gathering is the focus of this week's lecture
- Passive Information Gathering: This involves gathering information without interacting with the target, utilizing archived or stored information. Examples include Google searches. It can be difficult to perform as there should be no traffic to the target.
- Semi-Passive Information Gathering: This aims to profile the target like normal internet traffic by querying published name servers and examining metadata in published documents, avoiding active scanning for hidden content.
- Active Information Gathering: This involves detecting suspicious or malicious behavior by mapping network infrastructure, actively scanning open services, and searching for unpublished directories, files, and servers.
- Target Scanning: This involves trying various methods to find how systems announce themselves. Key parts include host discovery, port scanning, and operating system discovery. Identifying points of entry like server-side, client-side, web applications, and wireless are also important.
- Scanners: Tools used in target scanning include Nmap (GUI is Zenmap), Netcat, Superscan (at Foundstone), Angry IP scanner. Various scan types like Ping Sweep, TCP Port Scan, UDP Port Scan, and Operating System Discovery are mentioned. Nmap example shows how it scans for ports and services on a target.
- Banner Grabbing: A technique to gather information about a computer system's services running on open ports. This is done by connecting and reading the service's banner or message. Banner information provides service and software details.
- Banner Grabbing Tools: Telnet, Netcat (nc), and Nmap are examples. Netcat is a versatile tool used for networking tasks for system administrators and security professionals for reading and writing on TCP/UDP connections. Nmap offers scripts for banner grabbing.
- Countermeasures:
- Against Active Information Gathering: network segregation, disabling unnecessary services, firewalls, and intrusion systems. Removing banners and tracking network traffic are important for stopping information leakage
- Against Passive Information Gathering: reviewing public sources of information, checking for metadata before publication, using anonymous identities, reviewing whois database records, and considering private domain registrations. Keeping track of archives via tools like WayBack Machine, and implementing data lifecycle and elimination policies (trace the data deletion process) are important.
- Threat Modeling (Step 3): Understanding the threats, vulnerabilities, and assets is crucial. This modeling helps identify weaknesses.
- Threat Categories: The different types of attackers (petty criminals, organized crime, law enforcement) must be considered, along with vulnerabilities (i.e. missing encryption, software defects). Assets are critical (secrets, system integrity, and hardware value)
- Threat Modelling Approaches: Attacker-centric, Software-centric, and Asset-centric approaches can help identify vulnerabilities
- MS SDL Threat Modelling: This method involves describing the system, creating a checklist, and assessing impact to find countermeasures. It proposes tools (e.g. a Microsoft tool) for threat modeling. There are clear steps for following and a visual model of a web shop example
- Challenges: Interpreting threat models across different engineers can be challenging
Summary of Key Terms
- OSINT: Open-Source Intelligence
- Nmap: Network Mapper (a port scanning tool)
- Netcat: (nc) Networking tool
- SDL: Security Development Lifecycle (as applied to security)
