Homophonic Collisions: Hold Me Closer, Tony Danza
Reagan Short, Justin Ibarra

We’ll demonstrate a few practical approaches to exploiting human misunderstanding as a result of homophones to passively collect sensitive information, along with some redacted real-world examples. Domains registered for soundsquatting purposes are likely to be missed by typosquatting detection tools like DNSTwist. We will release defensive and detection mechanisms to help find vulnerable use cases within registered domains, language packaging pipelines, and social media handles.
