Unit III: Preparing for a Hack ( English )
Topic 1: Technical Preparation
Definition: Technical preparation involves setting up the tools, systems, and environments required to conduct an ethical hacking test effectively.
Subtopics:
Setting Up the Lab Environment:
Creating a controlled environment to simulate attacks without affecting live systems.
Tools like VirtualBox, VMware, or Kali Linux are used to set up virtual machines (VMs) for testing.
Example: Setting up a lab with a Windows VM as the target and a Kali Linux VM as the attacker machine.
Installing and Configuring Tools:
Installing ethical hacking tools like Nmap, Metasploit, Wireshark, and Burp Suite.
Configuring tools to ensure they work seamlessly during the test.
Example: Installing Metasploit Framework and configuring it to connect to a target system.
Understanding the Target Environment:
Gathering information about the target’s operating systems, network architecture, and applications.
This helps in planning the attack and selecting the right tools.
Example: Researching that the target uses Windows Server 2019 and Apache for web hosting.
Legal and Ethical Considerations:
Ensuring all activities are within legal boundaries and have proper authorization.
Example: Obtaining written permission from the organization before conducting a penetration test.
Mind Map/Crux Line: Technical Prep → Lab Setup, Tool Installation, Target Understanding, Legal Compliance → Ethical Hacking Readiness.
Topic 2: Reconnaissance Methods
Definition: Reconnaissance is the process of gathering information about the target system or network to identify potential attack vectors.
Subtopics:
Social Engineering:
Manipulating individuals to gain sensitive information or access to systems.
Techniques include phishing, pretexting, and baiting.
Example: Sending a phishing email that appears to be from a trusted source to steal login credentials.
Physical Security Reconnaissance:
Assessing the physical security measures of the target, such as access controls, surveillance, and locks.
Example: Posing as a maintenance worker to gain physical access to a server room.
Internet Reconnaissance:
Using online tools and techniques to gather information about the target.
Tools include Google Dorks, WHOIS lookup, and Shodan.
Example: Using Google Dorks (e.g.,
site:example.com filetype:pdf) to find sensitive documents on a company’s website.
Network Scanning:
Identifying active devices, open ports, and services on the target network.
Tools like Nmap and Angry IP Scanner are used for this purpose.
Example: Scanning a company’s network to find open ports like HTTP (port 80) or SSH (port 22).
Mind Map/Crux Line: Recon Methods → Social Engineering, Physical Security, Internet Recon, Network Scanning → Identify Attack Vectors.
Topic 3: Vulnerability Identification
Definition: The process of identifying weaknesses in the target system that can be exploited during an attack.
Subtopics:
Automated Vulnerability Scanning:
Using tools like Nessus, OpenVAS, and Qualys to scan for vulnerabilities.
These tools provide detailed reports on identified weaknesses.
Example: Running a Nessus scan to find unpatched software vulnerabilities on a target server.
Manual Vulnerability Assessment:
Manually testing for vulnerabilities that automated tools might miss.
Techniques include code review, configuration review, and penetration testing.
Example: Manually testing a web application for SQL injection vulnerabilities by injecting malicious queries.
Common Vulnerabilities:
Weak Passwords: Easily guessable or default passwords.
Unpatched Software: Outdated software with known vulnerabilities.
Misconfigured Services: Services with unnecessary permissions or open ports.
Example: Finding a server with an outdated version of Apache that is vulnerable to CVE-2021-41773.
Prioritizing Vulnerabilities:
Ranking vulnerabilities based on their severity and potential impact.
Example: Prioritizing a critical vulnerability like Remote Code Execution (RCE) over a low-risk issue like an open port.
Mind Map/Crux Line: Vulnerability ID → Automated Scanning, Manual Assessment, Common Vulnerabilities, Prioritization → Exploit Weaknesses.
Topic 4: Exploitation Planning
Definition: Planning how to exploit identified vulnerabilities to gain unauthorized access to the target system.
Subtopics:
Selecting Exploits:
Choosing the right exploits based on the vulnerabilities identified.
Tools like Metasploit and Exploit-DB are used to find and execute exploits.
Example: Using Metasploit to exploit a Windows SMB vulnerability (e.g., EternalBlue).
Payload Selection:
Deciding what action to perform after gaining access (e.g., installing a backdoor, stealing data).
Common payloads include reverse shells, bind shells, and meterpreter.
Example: Using a meterpreter payload to gain interactive access to the target system.
Avoiding Detection:
Using techniques to evade detection by security systems like firewalls and antivirus software.
Techniques include obfuscation, encryption, and using custom payloads.
Example: Encrypting the payload to bypass antivirus detection.
Post-Exploitation Planning:
Planning what to do after gaining access, such as maintaining access, covering tracks, and exfiltrating data.
Example: Installing a rootkit to maintain access and deleting logs to cover tracks.
Mind Map/Crux Line: Exploitation Planning → Select Exploits, Choose Payloads, Avoid Detection, Post-Exploit Actions → Gain and Maintain Access.
Topic 5: Reporting and Documentation
Definition: Creating a detailed report of the findings, including vulnerabilities, exploitation methods, and recommendations for mitigation.
Subtopics:
Report Structure:
Executive Summary: High-level overview of the test and its findings.
Technical Details: Detailed description of vulnerabilities, exploits, and impact.
Recommendations: Actionable steps to mitigate identified risks.
Example: A report includes an executive summary for management and technical details for the IT team.
Visual Aids:
Using diagrams, screenshots, and tables to make the report more understandable.
Example: Including a network diagram showing vulnerable systems and a screenshot of a successful exploit.
Deliverables:
Providing the report to stakeholders and conducting a debriefing session.
Example: Presenting the report to the organization’s management team and answering their questions.
Follow-Up Actions:
Ensuring that the organization implements the recommended security measures.
Example: Conducting a follow-up test to verify that vulnerabilities have been patched.
Mind Map/Crux Line: Reporting → Structure, Visual Aids, Deliverables, Follow-Up → Communicate Findings and Recommendations.
