⚔️ Metodología de Ataque

Primary Method: Credential Harvesting

The attacker is attempting to steal user credentials by creating a fake login page that closely resembles the legitimate bet365 website. Users entering their username and password will have their credentials stolen.

🌐 Indicadores de Compromiso de Infraestructura

🦠 Malicious Files

Main File
encforms.js (handles encrypted form submission) and checkinput.js (contains credential validation logic)
File Size

Functions: checkPassword(), checkConfirmPassword(), getcode(), $('#btnSubmit').click(), $.ajax() and $.post() calls in form submission handlers, playgame_modal() (likely a decoy or secondary payload delivery mechanism)

📊 Diagrama de Flujo de Ataque

1. Step 1: User lands on phishing page and fills out registration/login form (fields: userid, password1, confirmpassword1, realname, tel, email, question, answer)
2. Step 2: Form validation functions (e.g., checkPassword, checkEmail) execute client-side checks to mimic legitimacy
3. Step 3: On submission, $('#btnSubmit').click() triggers AJAX POST to /getcode with affiliate code or other data
4. Step 4: For login forms, encrypted credentials are sent via $.post('/login_action') using JSEncrypt to obfuscate payloads
5. Step 5: Server processes data (e.g., stores credentials, triggers secondary actions like fake 'success' alerts or redirects)
6. Step 6: Decoy functionality (e.g., playgame_modal) may distract users or deliver additional payloads
