Hacking Cycle

The hacking cycle is a systematic approach that hackers (both ethical and malicious) often follow to compromise systems or networks. Understanding this cycle can help organizations bolster their security measures. Here’s a detailed breakdown of the phases involved in the hacking cycle:

1. Reconnaissance

• Definition: This is the information-gathering phase where the hacker collects as much data as possible about the target.
• Techniques:
  • Passive Reconnaissance: Gathering information without directly interacting with the target. This can include social media research, DNS queries, and WHOIS lookups.
  • Active Reconnaissance: Direct interaction with the target through ping sweeps, port scanning, or vulnerability scanning to discover open ports and services.
• Objective: Identify potential vulnerabilities and points of entry into the target system.

2. Scanning

• Definition: This phase involves identifying live hosts and services, scanning for vulnerabilities.
• Techniques:
  • Port Scanning: Identifying open ports and services running on those ports using tools like Nmap.
  • Vulnerability Scanning: Utilizing automated tools to find known vulnerabilities in the system.
• Objective: Develop a profile of the target’s network to identify weaknesses that can be exploited.

3. Gaining Access

• Definition: This phase involves exploiting the vulnerabilities discovered in the previous phases to gain unauthorized access to the system.
• Techniques:
  • Exploitation: Using exploits against software vulnerabilities to execute code, elevate privileges, or gain access to restricted areas.
  • Password Cracking: Attempting to gain access using stolen, weak, or cracked passwords through techniques like brute force or dictionary attacks.
• Objective: Establish a foothold in the target system.

4. Maintaining Access

• Definition: Once access is gained, hackers often take steps to maintain their foothold within the system.
• Techniques:
  • Backdoors: Installing backdoor programs or rootkits to ensure continued access even after the initial vulnerability is patched.
  • Account Creation: Creating new user accounts with administrative privileges to access the system at will.
• Objective: Ensure long-term access to the compromised system.

5. Covering Tracks

• Definition: This phase involves erasing evidence of the hack to avoid detection by security personnel.
• Techniques:
  • Log Manipulation: Deleting or altering logs that record malicious activity.
  • Using Stealthy Tools: Employing rootkits or other stealth software that hides the hacker’s presence.
• Objective: Minimize the chance of detection and response by the target organization.

6. Exfiltration

• Definition: This phase involves extracting valuable data from the compromised system.
• Techniques:
  • Data Theft: Copying sensitive data such as customer records, financial information, or proprietary company data.
  • Establishing External Connections: Sending data to external servers controlled by the hacker.
• Objective: Monetize the hack by selling the data or using it for further malicious activities.

7. Analysis and Feedback

• Definition: After the attack, hackers may analyze their success and gather feedback on the process.
• Objective: Improve their techniques and strategies for future attacks.
