This week in the wild west roundup.

  • This week in the wild west roundup.
    • HashJack is a new indirect prompt injection technique.
      • It takes advantage of the fact that the content after a hashtag in a URL won't lead to errors if it's in a structure the page can't interpret… but the LLM can see it just fine.
      • A natural place to inject malicious prompt injection instructions!
      • I'm disappointed… Google normally has one of the best security teams in the industry.
      • How did they let this go out the door?
    • A universal AI jailbreak: make the prompts poems.
      • This just drives home that "make the LLM not get tricked" is a dead end.
