To protect against tools like Fileupload Gunner, organizations should implement the OWASP File Upload Cheat Sheet recommendations: Rename Files

To bypass server limitations on file size (like PHP’s upload_max_filesize ), the Gunner project breaks large files (e.g., 5GB videos) into tiny chunks ( ) and uploads them sequentially or in parallel. 3. Resumable Uploads fileupload gunner project
