Initial Reconnaissance
Reconnaissance is the first and crucial phase in penetration testing. It involves gathering as much information as possible about the target machine to identify vulnerabilities and potential entry points.
Port Scanning
The initial step in reconnaissance is to perform a port scan. This involves identifying open ports and the services running on them. By examining which ports are open, you can infer the types of services and applications that may be present on the machine. For instance, open ports might indicate the presence of a web server, database server, or other network services.
Service Enumeration
Following port scanning, the next step is service enumeration. This process involves probing the identified services to gather detailed information about their versions and configurations. Service enumeration helps in identifying specific vulnerabilities associated with the versions of the services running on the target machine. For example, if a web server is running, you might look for specific configurations or known vulnerabilities related to that server.
Vulnerability Identification
With information from reconnaissance in hand, the next phase is to identify vulnerabilities within the services and applications running on the machine. This involves:
Researching Known Vulnerabilities
Once you have information about the services and their versions, you can research known vulnerabilities related to those versions. Vulnerability databases and resources like security advisories can provide insights into common vulnerabilities associated with specific software versions.
Assessing Configuration and Security Practices
In addition to known vulnerabilities, it’s also important to assess the configuration and security practices of the services. Misconfigurations, such as overly permissive file permissions or weak authentication mechanisms, can also present security risks.
Exploitation
Exploitation is the phase where identified vulnerabilities are leveraged to gain access to the target machine. This involves:
Exploiting Web Servers
If the target machine has a web server running, common exploitation techniques might include:
- Directory Traversal: Accessing files and directories that are not intended to be exposed through web requests.
- File Upload Vulnerabilities: Uploading malicious files to gain unauthorized access or execute code on the server.
Exploiting Databases
For database servers, SQL injection attacks might be used to manipulate the database or extract sensitive information. SQL injection can allow an attacker to execute arbitrary SQL queries, which can lead to unauthorized access or data extraction.
Privilege Escalation
Once access is gained, the next step is privilege escalation, which involves elevating your access level to gain more control over the machine. This might include:
Finding and Exploiting Local Vulnerabilities
Privilege escalation often involves searching for local vulnerabilities or misconfigurations that can be exploited to gain higher-level access. This might include exploiting setuid binaries or other privileged processes.
Checking for Weak Permissions
Assessing file and directory permissions can reveal weaknesses that allow a user to gain elevated privileges. For example, if sensitive files or binaries have incorrect permissions, they might be exploited to escalate privileges.
Capturing the Flag
The final step in the challenge is to locate and retrieve the flag file. On most HTB machines, the flag file is located in a directory that requires elevated permissions to access. Common locations include:
- Root Directory: Typically accessible only by the root user.
