Mechanics of the Attack

Understanding the mechanics behind how hackers plant false memories in ChatGPT to steal user data in perpetuity is a bit like peeling the layers of an onion. It's intricate and can bring tears to your eyes—figuratively speaking—when you realize the potential for misuse. Here, I break down the process into digestible chunks, so even if you're not a techie, you can still follow the breadcrumbs to see how this cyber ruse unfolds.

Indirect Prompt Injection

Let's talk about indirect prompt injection, which is a sneaky way to create false memories in ChatGPT. Imagine receiving a message, and because of the way it's worded, you suddenly start remembering things that never happened. That's pretty much what hackers aim to do with prompt injection. They use cleverly disguised inputs to trick ChatGPT into storing fictional memories.

• How does it work? Well, hackers embed malicious instructions into content that appears harmless. This might be an email, a document, or even a blog post. When the AI processes these inputs, it follows the hidden commands without realizing they're bunk. For example, it might start believing you’re 102 years old or think you're living in a world entirely made up of pixels and binary code. This false data, once planted, becomes part of the AI's long-term memory setting and can skew all future interactions.
