Uncommon Unicode encodings can be used to manipulate the results of search engines and their chatbot counterparts. If an adversary can manipulate a user into copying a search term into a search engine, they can leverage this behavior to control the results.

This work will appear in RAID 2023 this October and was done with coauthors Luca Pajola, @iliaishacked, @rossjanderson, and @mauroconti_.

Imperceptible adversarial examples have now arrived for NLP. Unicode can be used to perturb text encodings in a way that targets ML models without affecting humans. Our techniques can be used to attack systems ranging from toxic content detection to machine translation.

I’m presenting this work in a paper titled "Bad Characters: Imperceptible NLP Attacks" coauthored with @iliaishacked, @rossjanderson, and @NicolasPapernot at IEEE S&P at 10:40am PT today. Come check it out.
