International Revenue Share Fraud (IRSF)

Thanks for sharing your interesting research! Can you explain your honeypotting approach further? How are you "presenting" as a SIP relay? What other honeypots or protocols can you detect?

Hell of an opening on this blog post. Solid write up! Glad honeypots like this exist.

This is quite the claim (and I'm not saying you are wrong from making it).

I just would have expected some of these institutions to be better.
