Receiving data from strangers is dangerous. While we generally consider iOS to be secure, but you know that there are numerous zero-day vulnerabilities. Who knows if this PDF file might contain a script that exploits one? Therefore, avoid accepting data from strangers and, ideally, change your AirDrop settings to "Contacts Only."

Yeah, that's about what I was thinking, that a zero-day would do it. Thank you. Fingers crossed.
