You Should Know:

Wireshark Commands & Usage:

Capture traffic on an interface:
```
wireshark -i eth0
```
Filter HTTP traffic:
```
tcp.port == 80
```
Save captured packets:
```
wireshark -w capture.pcap
```

Metasploit Framework Essentials:

Start Metasploit:
```
msfconsole
```
Search for exploits:
```
search exploit_name
```

Use an exploit:

use exploit/path
set RHOSTS target_ip
exploit

Nmap Scanning Techniques:

Basic scan:
```
nmap -sV target_ip
```
Aggressive scan:
```
nmap -A target_ip
```
Detect OS:
```
nmap -O target_ip
```

John the Ripper Password Cracking:

Crack a password file:

john --wordlist=/usr/share/wordlists/rockyou.txt hashes.txt

Show cracked passwords:
```
john --show hashes.txt
```

Burp Suite Web Testing:

Intercept HTTP requests:

Configure proxy (127.0.0.1:8080) in browser

Scan for vulnerabilities:
```
Use Burp Scanner for automated checks
```

Snort IDS Rule Example:

alert tcp any any -> any 80 (msg:"Possible SQLi Attack"; content:"' OR 1=1"; sid:1000001;)

OpenVAS Vulnerability Scanning:

Install OpenVAS:
```
sudo gvm-setup
```
Run a scan:
```
gvm-cli scan_target
```

Maltego OSINT Investigation:

Install Maltego:

wget https://maltego-downloads.s3.us-east-2.amazonaws.com/linux/Maltego.v4.3.0.deb
sudo dpkg -i Maltego.v4.3.0.deb

Run transforms:
```
maltego
```

The Sleuth Kit Forensics:

Analyze disk image:
```
fls -r /dev/sda1
```
Recover deleted files:
```
tsk_recover /dev/sda1 /recovery_folder
```

Steghide Data Hiding:

Hide data in an image:

steghide embed -cf image.jpg -ef secret.txt

Extract hidden data:
```
steghide extract -sf image.jpg
```

What Undercode Say:

Cybersecurity is a hands-on field, and mastering these tools is essential for professionals. Whether you’re analyzing network traffic with Wireshark, exploiting vulnerabilities with Metasploit, or conducting OSINT with Maltego, practical experience is key.
