US Secret Service 'Dismantles Telecommunications Threat' (bbc.co.uk) 74

mrspoonsi writes: The US Secret Service says it has dismantled a network of more than 300 SIM servers and 100,000 SIM cards in the New York area that were capable of crippling telecom systems.

The devices were "concentrated within 35 miles of the global meeting of the UN General Assembly now under way in New York City" and an investigation has been launched, it adds in a press statement.

The Secret Service says the dangers posed included "disabling cell phone towers, enabling denial of services attacks, and facilitating anonymous, encrypted communication between potential threat actors and criminal enterprises."

    Was the installation used to commit a crime?

    If not, why and under what authority was it dismantled?

    If so, any arrests? Names?

    Any known or suspected ties to existing threat actors or nation state intelligence?

    Right now this is Roscoe P Coltrane posing next to a pile of jugs. But it has the elements of something that might be interesting.

    • According to the article, the investigation was started after three congresspeople received threatening test messages last spring.

      Police can seize equipment in order to investigate possible crime, so long as they have probable cause to suspect the gear might be evidence, then they can take it in.

      Also, the location being Abandoned hotel rooms, and the unauthorized nature of the presence of many racks' worth of gear being installed there by the owners of the property is probably plenty probable cause.

      Was the installation used to commit a crime?
      It sounds like they are still investigating. The article does not mention any crime as being alleged, Only that the network they seized in theory would be capable of causing disruption if the operators had wanted it too.

          They didn't say it was in NYC proper. They said it was 'within 35 miles of the UN', which means it was someplace, maybe Long Island, maybe Trenton NJ.

          Just bc rent is high in NYC does not mean they have no buildings being kept empty.
          There must be, since the news indicates the seized network was scattered across 5 sites. In short; they were hidden within rooms in 5 different abandoned buildings - not just one.

          • It doesn't need to be a whole abandoned building - just a specific abandoned spot within it. If anything, a building still otherwise in use would be superior, more noise to hide the power draw in.
            I've watched some some specials on NYC buildings. "Useable" floorspace getting walled away or even just forgotten behind a locked door happens regularly. Inheritances, will disputes, remodeling snafus, and more.

            As for the use of the servers themselves - I'm guessing they were used to make scam calls and such usi

              The BBC's version of the article stated abandoned buildings.

              But sure. Find a room not being used at the end of some hall. Create some means of covert entry into the space from outside like a new hatch cut behind a bush, or whatever. Quietly frame up new walls inside the building during some holiday while everyone is gone and nobody's looking.. Fresh coat of paint to match surroundings, coat rack, or

              • I've been thinking about this some. It's NYC, so entry from outside would imply a ground floor, less than ideal. Maybe climbing up a fire escape would work.

                Making it look like a utility closet would probably work well. Still have access from inside, not restricted to where you can get at it from outside the building. All depends on the access rating of the place, of course. For example, a painted wooden panel screwed onto the wall concealing the entrance. Sure, can't access it on a whim, but could sit

          Builldings get abandoned when the owner is unable to rent them out: Either due to regulatory reasons, such as the city won't issue the necessary permits, Or due to the lack of anyone willing to currently pay the demanded per square-footage rent on the rooms or the space.

      The were being used to threaten and swat government officials on both sides of the aisle over the last few years. The Secret Service found them by tracking the SIM numbers that the threats originated from.

      The sheer volume of the SIM cards and distribution of the installations indicates there were plans for far more than just anonymous threats to officials, because that volume of devices could easily overload the cell network. .

      If you see something that looks like a bomb next to a bank you don't wait until the bomb has detonated to remove it. You remove it while you can and then figure out later if it actually WAS a bomb.

      The U.S. Secret Service dismantled a network of electronic devices located throughout the New York tristate area that were used to conduct multiple telecommunications-related threats directed towards senior U.S. government officials, which represented an imminent threat to the agency’s protective operations.

      This is Pre-Crime buddy, get with the times.

  • This would not surprise me if the entire setup is designed to give people cellphone service without having to pay somebody.

    All the things they talked about being 'possible', seem to me like you could do similar things by hacking, for a lot less money and effort.

    • Then why all the SIM cards and thousands of individual radios? That's not how a cell site works.
    • I'm actually thinking that it would be "make VOIP calls look local and avoid mass shutdowns for spamming people with scam calls."

      They then rent the service out globally to said scammers from China, India, even Pakistan and North Korea.

  • The real reason: "facilitating anonymous, encrypted communication between potential threat actors and criminal enterprises."

    Which implies they view encryption and anonymity as an implicit threat.

      The FBI and DHS are now focused on Trump's round-up of illegal aliens.

    • Once you threaten a public official, as happened in this case, the Secret Service is involved. The SS is also involved in protecting foreign dignitaries when they come to this country.

      Thus, with the UN session going on, they were doing what they should. They were probably (most definitely) working with the FBI and DHS, possibly even NSA, on this.

  • I read the article and it's not clear how they determined that it was meant for interfering with the telecommunications system. Could it also be a phone bot farm for social media influencing and such? I mean, I'd want that taken down as well. I just wonder how they determined what its intended purpose was.
    • by cusco ( 717999 )

      Pretty much how they always determine that sort of thing, they reached into their nether regions, pulled something out, washed it off and said, "We saved the world AGAIN!!!"

    • Does that make sense though? "Bot farms" are legal and operate openly. This doesn't seem to have been a registered business, and it was operating out of a New York City apartment.
    • Seems to me that it could not be used for ddos, since a thousand sim cards in one place would immediately saturate the cell they were talking to, and not be able to do ddos over a whole city.

  • Does anyone have experience with the devices in the pictures? They kind of look like rack mount switches, but they have all these antennae sticking out. I've never seen a device like that. Is it an off-the-shelf piece of equipment? What are they typically used for?

    CNN has a much better article going into far more detail [cnn.com] than the BBC blurb.

    The main thing that got these on the radar of the Secret Service was swatting and threatening government officials (both Democrat and Republican) via phone calls and texts from these devices. After several months of tracking the SIMs these calls were originating from, and trying to find their physical locations, they discovered these SIM servers.

    The sheer volume of them - 100,000 unique SIM cards housed in 300 servers spread across multiple locations (rented apartment spaces and the like) is way, way more than needed to just harass government officials. That volume of devices could easily overload the cellular network and bring it down.

      That's because that's not their primary purpose. They were used to send SMS spam, bots to click on links on facebook, youtube, etc. They got busted because one of their customers used them for something nefarious.

    • The actual BBC article is better: https://www.bbc.com/news/artic... [bbc.com] The Slashdot summary linked to a BBC blog item rather than an article.
    • If I were a betting man, someone set those up to do illegal telemarketing and then decided to sell access to folks who paid more than telemarketing did. I did notice a sudden drop in spam calls recently. It was 9 times a day and now it is only 1 every 2 days.

    Move along now. These are just more advanced versions of phone farms. Back in the old days, people used to get dozens (hundreds) of second hand phones and use them to generate SMS spam for telemarketing. These are just a more hardware efficient means of doing so.

    Seized actual SIM cards? That's so last decade. These things are mainly eSIM now. Law enforcement tries to kick down your door and shut you down? The virtual SIMs can be moved to new servers across the country in a few milliseconds. Long before the battering rams finish work on your front door.

    Anecdote: We have a few farms in a town near me: Bothell, WA. My telco (with a good sense of humor) identifies them on caller id as originating in "Bot-hell".

        Because SMS is just ONE of the several things they are used for. They are used to get 100s of thousands of different IP addresses to click on links at websites for all kinds of fraud and manipulation. Ad revenue theft, voting on polls, posting bot comments with fake accounts, etc.

          No, you don't need those for IP spoofing.
