: Attackers use NULL to figure out exactly how many columns the original database table has. If the number of NULL s matches the columns, the page loads; if not, it crashes.
Modern web development has largely moved past this threat using a technique called (or Parameterized Queries). Instead of letting user input mix directly with the code, the database is told: "Treat this input strictly as text, no matter what symbols are inside it."
If a website is vulnerable to this, an attacker doesn't just stop at NULL . They eventually replace those NULL s with commands to extract sensitive info—like your —and display them right on the screen where the "Keyword" results should have been. How Developers Stop This

The Trouble with Tribbles is such a classic episode. It’s on my list of stuff to rewatch when I’m having a bad day and need a pick-me-up. (I get the winter blues, so I really appreciate Tribbles and other fun scifi stuff during the winter in particular. :) )
I think it’s awesome that it’s on your pick-me-up list. :) Sometimes I like to just look at the gif of Kirk after all the tribbles fall on him because it’s one of the few things I can count on to always make me laugh!
Heh, for sure!
