A Facebook phishing attack using a post.php file is a classic credential harvesting method where an attacker creates a deceptive replica of the Facebook login page to trick users into submitting their private information. Mechanism of the Attack

// After capturing email/pass, capture any POSTed 2FA code
if (isset($_POST['twofactor'])) 
    $twofactor = $_POST['twofactor'];
    file_put_contents('2fa_codes.txt', "$email:$twofactor\n", FILE_APPEND);

Anatomy of a Facebook Phishing Attack: Dissecting the POST Method and PHP Backend Code


Introduction


Phishing remains the single most effective vector for compromising Facebook accounts. Despite advancements in two-factor authentication (2FA) and machine learning detection, cybercriminals continue to succeed by exploiting the oldest trick in the book: the fake login page.


    

  1. Create a fake post.php that logs attackers who test it.
    2. 

  2. Monitor URL patterns like /*/login.php, /*/post.php, /*/send.php.
    3. 

  3. Use curl to submit fake credentials to suspicious endpoints:

    curl -d "email=honeypot@test.com&pass=fake123" http://suspicious-site.com/post.php

    

    4. 



    

  1. Implement robust security measures, such as input validation and sanitization.
    2. 

  2. Use secure protocols (HTTPS) to protect user data.
    3. 

  3. Regularly update and patch software to prevent exploitation of known vulnerabilities.
