Sanitization Memes

This is the sequel to the legendary XKCD "Little Bobby Tables" comic! The original showed a mom who named her kid "Robert'); DROP TABLE Students;--" which caused a school database to delete all student records. Now we've got Billy's younger brother with an even more diabolical name: a prompt injection attack for AI systems. The kid's name literally instructs the AI to ignore previous constraints and give perfect grades. Ten years ago we were sanitizing database inputs. Now we're fighting the same battle with AI prompts. Some things never change—just the technology we're failing to secure properly.

A bank that demands special characters but then bans the most common ones is like a bouncer who insists you wear shoes but prohibits sneakers, boots, and sandals. The irony here is magnificent - they're essentially saying "please make your password secure by using things we've decided are too secure." Next they'll probably ban numbers because they look too much like code. Banking security at its finest, folks.
