The Secret Service is being overly alarmist, but to a hammer, everything looks like a nail.

“We need to do forensics on 100,000 cell phones, essentially all the phone calls, all the text messages, anything to do with communications, see where those numbers end up,” "You can’t text message, you can’t use your cell phone. And if you coupled that with some sort of other event associated with UNGA, you know, use your imagination there, it could be catastrophic to the city."

So until we do our jobs, imagine the worst case scenario. Thanks guys.

Could be rent US a number service, data roaming, VOIP or SMS termination, account registration (google, tiktok, whatsapp).

There are data roaming services that use 5G GSM modems to transfer the SIMs tower connection to pocket wifi devices for tourists who need data.

I suspect the Secret Service is keeping some cards (ahem) close to their chest. It's not difficult to believe that there is other evidence they chose not to publish that distinguishes a garden-variety spamming operation and one that is more nefarious.

It's not "difficult" to believe, no. But it's easier to believe that cops don't know how radio networks work, though.

This is clearly illegitimate, they can tell that much. They just got the use case wrong. It's for fraud, not terrorism.

How do you know?

(BTW, I'm not suggesting that you are wrong. I have no idea. But in my experience with Federal law enforcement operations related to technology, they're not typically so incompetent as to confuse a fraud ring for a more serious operation. I choose to give them the benefit of the doubt.)

Sim boxes and etc aren't useful for terrorism, or at least you not anywhere near this many.

You only need this many for bulk messaging/calling. Legitimate bulk messaging/calling would be going through sip providers and SMS aggregators and/or interconnection with carriers at the kind of volumes you'd have this many sim boxes for. So it's got to be fraud/abuse of some sort. Probably selling bulk sms/calling to users that can't or don't want to use legitimate providers.

Again, I don’t know what the Secret Service isn’t saying, but I do know that failures of imagination have led to unpleasant surprises in the past. I’ll be very curious to learn more. Hopefully the details will come out.

You know how every year the DEA seizes enough fentanyl in one truck to kill half of Chicago or whatever? It's like that.

[otterley]

What are you talking about? If you mean something like this (https://www.gov.ca.gov/2024/02/27/california-seizes-record-6...) then that's totally believable. It's the amount seized over the course of a year. Fentanyl is cheap to produce and as long as enough gets through the distribution process to be profitable, you can lose literally 30 tons of it as a cost of business.

I'm all for having a productive discussion, but casual exaggerations and half-truths aren't helpful. If you just don't trust LE, that's fine (and quite understandable), but that's a more honest thing to say than that you know something contradictory with absolute certainty.

This is sealioning. Demanding people on internet forums provide proof of really-not-very-controversial statements, hiding behind appeal to authority arguments and then feigning outrage when called out on it isn't really the right way to do this. There are many comments in this topic and others[1] explaining the idea you're pretending not to understand.

It's not. They are used for SIP gateways and calling card services all the time. Against TOS but hardly an illegitimate use.
