Tools and Techniques

1. Web Application Exploitation

• Tools: nmap, gobuster, sqlmap, nikto, hydra
• Techniques:
  • Directory and file enumeration.
  • SQL injection and XSS exploitation.
  • File upload vulnerabilities and reverse shells.

2. Reverse Engineering

• Tools: Ghidra, Radare2, GDB, strings, binwalk
• Techniques:

• Techniques:
  • Capturing WPA/WPA2 handshakes.
  • Cracking Wi-Fi passwords with wordlists.
  • Exploiting WPS vulnerabilities.

4. Windows Machine Exploitation

• Tools: smbclient, enum4linux, mimikatz, winPEAS
• Techniques:
  • SMB enumeration and exploitation.
  • Privilege escalation with token impersonation and kernel exploits.
  • Dumping credentials with mimikatz.

5. Apache2 Server Exploitation

• Tools: nikto, gobuster, sqlmap, metasploit
• Techniques:

  • Log poisoning and reverse shells.
  • Privilege escalation on Linux servers.

6. SQL Injection Exploitation

• Tools: sqlmap, Burp Suite, hydra
• Techniques:
  • Error-based, Union-based, and Blind SQL injection.
  • Bypassing authentication and dumping database contents.
  • Exploiting file read/write vulnerabilities.

Usage

To use this repository, clone it to your local machine:

git clone https://github.com/your-username/ctf-toolkit.git
cd ctf-toolkit

Example: Exploiting SQL Injection with sqlmap

1. Scan for SQL injection vulnerabilities:

   sqlmap -u "http://target.com/login.php?username=admin&password=123" --dbs

2. Dump database tables:

   sqlmap -u "http://target.com/login.php?username=admin&password=123" -D database_name --tables

3. Extract data from a table:

   sqlmap -u "http://target.com/login.php?username=admin&password=123" -D database_name -T table_name --dump
