Handling user-generated files exposes your infrastructure to severe security risks, including malware execution, Denial of Service (DoS) attacks, and unauthorized data access. The FileUpload Gunner Project provides robust security features to mitigate these risks. Magic Number Validation (MIME-Type Checking)

Always verify that you are using the correct file version for your specific machine (e.g., GG2 vs. GG3). 1911 frame 2. Chunked / Multipart Uploads
Attackers frequently name files image.jpg.php to trick naive validation routines that only check for the presence of .jpg . The project automates these double extension arrays alongside null byte injections (e.g., shell.php%00.jpg ) to see if the backend improperly truncates string names during storage. 3. Content-Type and Magic Byte Spoofing including malware execution
The client uploads the binary payload to the storage bucket. The application server never touches the raw file bytes. 2. Chunked / Multipart Uploads
