One of the more fun things to note is bad actors don’t need to be a telecoms operator or pay one for access to SS7 - a lot of the software involved for management is horribly insecure and often exposed to the internet by smaller operators. The biggest barrier to entry for hacking SS7 networks is just gaining the network access. And that gate is often secured with some shoddily written mess of old code.
