You Should Know:
Wireshark Commands & Filters
- Capture traffic on a specific interface:
wireshark -i eth0
- Filter HTTP traffic:
http
- Filter DNS queries:
dns
Metasploit Framework Usage
- Start Metasploit console:
msfconsole
- Search for exploits:
search exploit_name
- Set payload and execute:
set payload windows/meterpreter/reverse_tcp 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 hash file:
john --format=raw-md5 hashes.txt
- Use a wordlist:
john --wordlist=/usr/share/wordlists/rockyou.txt hashes.txt
Snort IDS Rule Example
alert tcp any any -> any 80 (msg:"Possible SQL Injection"; content:"' OR 1=1"; sid:1000001;)
OpenVAS Scan Setup
- Install OpenVAS:
sudo apt install openvas
- Launch scan:
openvas-start
Burp Suite Proxy Interception
1. Configure browser proxy to `127.0.0.1:8080`.
2. Enable Intercept in Burp Suite.
3. Modify HTTP requests in real-time.
Maltego Data Mapping
- Install Maltego CE.
- Run transforms to map domain relationships.
The Sleuth Kit Forensic Analysis
- List files in a disk image:
fls -r /path/to/image.dd
- Extract a file:
icat /path/to/image.dd inode_number > output_file
Steghide Data Hiding
- Hide a file 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. Wireshark helps in network forensics, while Metasploit is crucial for penetration testing. OpenVAS and Nmap assist in vulnerability assessment, whereas Burp Suite is indispensable for web security. Snort provides real-time intrusion detection, and John the Ripper strengthens password security. Maltego aids in OSINT investigations, The Sleuth Kit in digital forensics, and Steghide in steganography.
To excel:
- Practice in controlled environments (e.g., Kali Linux, Hack The Box).
- Automate tasks with Bash/Python scripts.
- Stay updated with security patches and CVE databases.
Expected Output:
A well-structured cybersecurity lab report detailing findings from Wireshark captures, Metasploit exploits, and Nmap scans, along with remediation steps.
