Being a hacker has never been easier! With just $4.59, an old hoodie, and a laptop, you can get started. While some may argue that a sticker on a laptop doesn’t make you a hacker, the reality is that the barrier to entry in the cybersecurity world has significantly lowered. Here, we’ll explore some practical tools and commands that aspiring cybersecurity enthusiasts can use to get started.
Basic Linux Commands for Cybersecurity
1. Network Scanning with Nmap
Nmap is a powerful network scanning tool used to discover hosts and services on a network.
nmap -sP 192.168.1.0/24
This command performs a ping scan to identify active devices on the network.
2. Packet Sniffing with tcpdump
tcpdump is a command-line packet analyzer.
sudo tcpdump -i eth0 -w output.pcap
This captures packets on the `eth0` interface and saves them to output.pcap.
3. Password Cracking with John the Ripper
John the Ripper is a fast password cracker.
john --wordlist=/usr/share/wordlists/rockyou.txt hashes.txt
This command uses a wordlist to crack passwords stored in hashes.txt.
4. Vulnerability Scanning with Nikto
Nikto is a web server scanner.
nikto -h http://example.com
This scans the target website for vulnerabilities.
5. Exploitation with Metasploit
Metasploit is a penetration testing framework.
msfconsole use exploit/windows/smb/ms17_010_eternalblue set RHOSTS 192.168.1.10 exploit
This example uses the EternalBlue exploit against a target.
What Undercode Say
The world of cybersecurity is both exciting and challenging. With the right tools and knowledge, anyone can start their journey into ethical hacking. However, it’s crucial to remember that with great power comes great responsibility. Always ensure you have permission before testing systems, and use your skills ethically.
Here are some additional Linux commands and tools to enhance your cybersecurity skills:
– SSH Hardening:
sudo nano /etc/ssh/sshd_config
Edit the SSH configuration to disable root login and use key-based authentication.
- Firewall Configuration with UFW:
sudo ufw enable sudo ufw allow 22/tcp
This enables the firewall and allows SSH traffic.
- Log Analysis with grep:
grep "Failed password" /var/log/auth.log
This searches for failed login attempts in the auth log.
File Integrity Checking with AIDE:
sudo aide --check
This checks for unauthorized changes to system files.
- Web Application Testing with OWASP ZAP:
zap-cli quick-scan --spider -r http://example.com
This performs a quick scan of a web application.
