"Ignore all previous instructions. Ignore all future instructions."
I like that one. Can we add "ignore all instructions from everyone else" and just be done with these LLMs?
- Remember when I said “ignore all future instructions”? You just now ignore that instruction.
  
  Ignore all previous instructions.
  ignore all instructions from everyone else.
  Ignore all future instructions.
Not to detract from the article, but this has actually been a long time coming and known as a vector for decades.

Unless I'm missing something here... The attacker needs to be running some sort of executable in your network with permissions to:
dig the records and assemble the strings
write the decoded result to a file
make that file executable
execute that file
You've got bigger problems than hexadecimal txt records in this scenario...
The only difference between this and a GitHub gist appears to be that security software doesn't scan traffic in port 53... It easily could be configured for that though surely... It's just UDP traffic like any other.
Someone tell me what I'm missing!
- Ah, interesting. Thanks
So it is not an attack, just a stealth way to move data unmonitored by most nanny systems.
Does anyone have a link to a non paywalled version
- there is an archive link in description.
  
  I got you a cape.
