Apparently there's an imposter pretending to be me and messaging infosec and infosec-adjacent folks cold on Signal (or, at least these are the people reporting it).
So, for the record I will NEVER cold message people on Signal. If you don't know me, or we didn't connect explicitly via a contact or at an event, I will not reach out to you. Ever. I have, like, better things to do, for one...
