This challenge demonstrates that SQL injection isn't just about bypassing logins; it can be used to exfiltrate sensitive data URL-encode or double-encode characters

• URL-encode or double-encode characters.
• Use concatenation or comments to split restricted keywords: e.g., s//elect or SEL//ECT.

• Use case variations and alternate encodings (Unicode, hex) where supported.
