I posted about it a while back. Lawrence has been following this and has an update linking it to China:
Well, as suspected, it was China’s.
This was in fact my first thought: Smells like a State Actor.
Having thought about it, I suspect it is linked to the PRC, but "outsourced" to US-based Bad Guys. This seems a business (selling infrastructure to send out floods of voice mail spam). It looks like the guys who ran this also let people swat folks they didn't like. In fact, this is how they got caught because one of the victims was a Congressman.
And so a lack of Opsec led to compromise of the whole system. Cry me a river.
And Lawrence has a great suggestion:
If theses SIM farms are active, there should be ways for telecomms to algorithmically search for mobile call hotspots where too many calls issue from too small an area. Let’s hope they’re doing that and working with various U.S. three letter agencies to shut them down right now.
Endorsed.

I'm like you. I don't answer nothin. If I don't recognize the number it goes to voicemail.
Why would the telecoms help shut down actors like this. Don't they profit from every device active on their network? Even the malevolent ones.
And how many of those "malevolent actors" are from the government in their own country? And that they are afraid of offending lest they no longer be able to operate in said country?
My thoughts exactly. Telecoms could easily take it down but they make money. Half a cent per call times 10 billion.
