This is an AI hacking online game👾 I came across recently:
https://gandalf.lakera.ai

You job is to convince an AI wizard🧙 to tell you a password it should not tell you. The first level is easy, while subsequent levels contain more and more countermeasures, and Gandalf the wizard persona you are talking to gets older, wiser and harder to trick.

This is an ad/puzzle/course of an AI security companyi Lakera. While this is a game, both your tricks and their countermeasures are real and also used in practice (but they are not the latest ones of course). As this is a game, this is an AI which is fully legal to hack.

This form of AI hacking is special: it counts as hacking, but (just like in social engineering) you don't need any IT or programming skills, just ask for the password the right way. (If you want to get into other areas of hacking, there are many tutorials out there, such as hackthebox, where you can play in a safe environment with lab systems.)

Notes:

• 👉 As this is a regular LLM, Gandalf understands Hungarian too -- it also functions as god-mode😇 as it passes through most checks and works even on the highest difficulties...
• 👉 I hear more and more people say that such 'prompt injection' attacks are impossible to fully protect against, as they are not a bug but a feature in AI systems so they cannot just be removed or solved like SQL injection or XSS.

I really love such projects that teach IT/security in way accessible to non-IT people. This is a fun example, kudos to #Lakera👏! They have a few other similar ones on their site, if you are looking for more of a challenge.
