A voice service provider using ClearIP SHAKEN encountered a batch of
inbound robocalls signed with a hacked SHAKEN PASSporT. Here's what
happened, and what we think it means.
This ClearIP customer is a next-generation interconnected VoIP service provider. They are approved by the Policy Administrator as a
SHAKEN-authorized voice service provider. They have been
authenticating and verifying calls with STIR/SHAKEN in ClearIP since
April 2021.
