My presentation focused Bad Actors who don't register with anybody. But after my presentation, Jon Peterson (who wrote much of the SHAKEN RFCs) added another security gap in the American implementation: anybody can get an OCN and CLLI code, access to numbers, get a Service Provider Token and a signing Certificate from the PA/CA, and then sign every call they want to from any number they want to.

I think the entire point of S/S (can we abbreviate this yet?) *is* the bad actors. Yes, an entity can go through all the hoops to sign calls, and their traffic will become immediately identifiable. It shouldn't take long for their certificate to get revoked while the FCC and others work on fining them out of existence with possible criminal charges with jail time.
