: This is SQL shorthand to comment out the rest of the legitimate code, ensuring the injected command runs cleanly. The "DJGP" Element Tools like Sequelize, Eloquent, or Entity Framework handle
In the world of cybersecurity, "DJGP" or similar tags are often used as unique identifiers by automated scanners or bug hunters. When a researcher (or a bot) sends this payload, they aren't looking to steal data immediately—they are looking for a .
