💡 File Upload Vulnerabilities
Insecure file upload functionality allows attackers to upload web shells, malware, or scripts that execute on the server. Proper validation must check file content, not just extensions, and uploaded files should be stored outside the web root.
💡 Bulletproof Hosting Ecosystem
Bulletproof hosting providers deliberately ignore abuse complaints, creating safe havens for malicious operations. These providers often operate in jurisdictions with weak cybercrime enforcement, offering services specifically marketed to criminal organizations.
