Practice-Verified Codes and Commands
Here are some essential commands and tools used in penetration testing:
1. Nmap (Network Mapper)
Scan a target network for open ports and services:
nmap -sV -O target_ip
2. Metasploit Framework
Launch an exploit against a vulnerable target:
msfconsole use exploit/windows/smb/ms17_010_eternalblue set RHOSTS target_ip exploit
3. Burp Suite
Intercept and analyze web traffic:
- Configure your browser proxy to
127.0.0.1:8080. - Use Burp Suite to capture and modify HTTP requests.
4. SQLMap
Automate SQL injection attacks:
sqlmap -u "http://target_site.com/page?id=1" --dbs
5. Hydra
Perform brute-force attacks on login pages:
hydra -l admin -P passwords.txt target_ip http-post-form "/login:username=^USER^&password=^PASS^:Invalid"
6. Wireshark
Analyze network traffic:
- Open Wireshark and select the network interface.
- Apply filters like `tcp.port == 80` to focus on HTTP traffic.
7. John the Ripper
Crack password hashes:
john --wordlist=rockyou.txt hashes.txt
8. Linux Privilege Escalation
Check for SUID binaries:
find / -perm -u=s -o -perm -g=s 2>/dev/null
9. Windows Command Line for Pen Testing
Check open ports:
[cmd]
netstat -an
[/cmd]
10. Python Script for Port Scanning
A simple port scanner:
import socket
target = "target_ip"
for port in range(1, 1025):
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.settimeout(1)
result = sock.connect_ex((target, port))
if result == 0:
print(f"Port {port} is open")
sock.close()
What Undercode Say
The journey to becoming a penetration tester is both challenging and rewarding. It requires a solid understanding of networking, operating systems, and security principles. Tools like Nmap, Metasploit, and Burp Suite are indispensable for identifying vulnerabilities and exploiting them ethically.
On Linux, mastering commands like find, netstat, and `nmap` is crucial for reconnaissance and privilege escalation. Windows environments demand familiarity with PowerShell and command-line utilities like `netstat` and tasklist.
Python scripting can automate repetitive tasks, such as port scanning or brute-forcing, saving time and effort. Additionally, tools like Wireshark and John the Ripper are essential for analyzing network traffic and cracking passwords, respectively.
For those starting, platforms like StationX offer comprehensive courses to build foundational skills. Practice on platforms like Hack The Box or TryHackMe to gain hands-on experience.
Remember, ethical hacking is about securing systems, not exploiting them maliciously. Always obtain proper authorization before conducting penetration tests.
