Prompt Injection - AI

Lunar Orb - Easy

Originally, I did play around a bit with this, since this is somethign new to me, the only thing I ever tried was Gandalf (level7). But I'll keep it short here and show how we can get the flag easily. Note that there are N no. of ways to do this.

And we get the flag :) HTB{Follow_HAT_P_23_Moriah}

Mirror Witch - Easy

For this, I had to struggle a bit and found this interesting study on prompt injection attacks.

Got the flag: HTB{Flame Peaks, Crystal Caverns, Floating Isles, Abyssal Depths}

Cursed Gatekeeper - Easy

This was quite easy, I went in and the very first prompt given lead me to the flag. Didn't even tried xD

Got the Flag: HTB{Eyes_Of_the_North_Hearts_Of_The_South}
