US Feds Are Tapping a Half-Billion Encrypted Messaging Goldmine (404media.co) 77

An anonymous reader shares a report: U.S. agencies are increasingly accessing parts of a half-billion encrypted chat message haul that has rocked the global organized crime underground, using the chats as part of multiple drug trafficking prosecutions, according to a 404 Media review of U.S. court records. In particular, U.S. authorities are using the chat messages to prosecute alleged maritime drug smugglers who traffic cocaine using speedboats and commercial ships.

The court records show the continued fallout of the massive hack of encrypted phone company Sky in 2021, in which European agencies obtained the intelligence goldmine of messages despite Sky being advertised as end-to-end encrypted. European authorities have used those messages as the basis for many prosecutions and drug seizures across the continent. Now, it's clear that the blast radius extends to the United States.

  • Well, expecting criminals to implement encryption right is probably too much to ask. At least for small-time criminals. Clearly, this "Sky" service was not actually end-to-end encrypted in the usual understanding of what that entails. I do not remember what the vulnerability here was, but probably keys stored on end-devices could be accessed via a software update or remote administration interface. End-to-end generally assumes that is at least hard to do and the end-device is actually under user control in

      • There's almost certainly a clause buried somewhere in the EULA indicating that you won't use the service to break any laws. That's pretty standard boilerplate for EULA terms, so anyone committing crimes on the platform doesn't have much to stand on. Non-criminal persons (good luck, you're probably guilty of something [lawcomic.net]) may have a case, but would probably have difficulty showing damages.

          Encryption is just one part of the stack. A lot of people want to combine the encryption mechanism and transport mechanisms, leading to it being easy to be compromised. One even needs to consider endpoints as well, and that easy to use iPhone isn't going to be secure against the level of nation-states, period. Same with that Windows PC with Microsoft CoPilot and MS Recall, allowing forensics to see what it was doing, second by second.

      Clearly, this "Sky" service was not actually end-to-end encrypted in the usual understanding of what that entails.

      Of course it was. In fact for a long time they ran an uncollected $5million bounty to see if anyone could crack the communication. The issue appears to have been the distribution of a fake "Sky" app which was compromised by Dutch police which in turn led to arrests which in turn led to access to devices which in turn led to more communications exposed and more arrests.

      Your end to end encryption is useless if I take your unlocked phone from you and read your messages on your own screen.

    • The encryption is only as good as the update mechanism and the key exchange.

      Lets say Signal was completely taken over by the CIA/NSA. They could NSL Google and Apple to selectively push updates with compromised apps (the odds of criminals checking reproducible builds is very small) or they could take over the servers and get the mobile phone company to fuck with the mobile phone account of someone central and the next time there's key exchange do a MITM attack (the odds of criminals doing in person safety n

      • by gweihir ( 88907 )

        Obviously. End-to-end does include that the end-device needs to be secure. And quite a few other things.

        As to MITM, no. That does not work with properly implemented end-to-end encryption.

        • MITM always work as long as you control the original key exchange, no amount of ratcheting helps if they can fool you about the identity of the other party, that's why the safety numbers exist.

          You can't compromise that after the fact, without a nasty warning about identity key changes due to pinning, but you can manipulate someone into reregistering and do the exchange "right" the second time.

          • by gweihir ( 88907 )

            That is complete nonsense. A proper key-exchange is not vulnerable to MITM. You are probably talking about key distribution, which is an entirely different question. Sure, if you do not have an authentic key of your communication partner, MITM becomes possible. But even a bloody amateur could see that, so authentic keys are obviously assumed.

            • Proper key exchange requires a pre-existing secure channel to solve identification.

              So in this case the secure channel set up by the server public keys in the app and an uncompromised server. Break those assumptions and what's left is improper key exchange, indistinguishable from proper. All the app can do is pin keys and hope the server was not yet compromised and allow checking of safety numbers (which next to no one does).

  • I'll be interested to see if this makes people lose faith in services like Signal. Which, I think the feds running a fake phone company was totally designed to do as well.
    • by CAIMLAS ( 41445 )

      Yeah, I have no pretense of Signal actually being secure end-to-end at this point. It's well known that it's used by CIA to both monitor opponents using it, and that they use it for their own ends.

      • Citation?
      • Do you have a source for that? Everything I've read on the CIA and Signal indicates that Signal is safe and the CIA got the info through other vectors.
      • The likely ploy is that Signal is secure - which entices users to say things they should not on insecure endpoints, which are intruded by MWG's..

        However they tipped their hand with their "spam checks" - we now know the servers can shut down any endpoint they want and with sufficient traffic correlation that can be rather specific.

        So, good for chatting about groceries but don't plan your next Venezuelan coup on it.

        Signal uses what I'm calling Zen-fu. It does what it says it does. It also does 2 things that "people" just shrug and ignore as irrelevant. So the gambit is no secret, but "people" are too dense to understand that meta-data can be more valueable than the actual content of your messages.

      • No, it's almost certainly secure end to end at the moment. It's just not entirely relevant.

        In an extreme emergency America's hold over Google/Apple allows them to compromise the encryption with updates.

The advantage of a centralized service with servers in the US ... it's in their best interest to not compromise the encryption outside of extreme emergenc

    • It depends on the attack profiles. To keep stuff private between friends and not go outside of this, something E2EE like Signal is good enough. However, when the value of the info is so high that it attracts nation-states' attention, then just trusting an app on a consumer grade device isn't going to do the trick.

      For what I do, Signal is secure enough. I'm well enough assured that when something falls off a chat in a day or so, it is gone forever, like a picture of a new 3D print I made. However, if thi

          Their immediate next step, however, is to appraise which other global actors might also be aware of the vulnerability. They'll gauge this by measuring the depth of research required to identify the vulnerability and correlate that to estimates of dedicated research resources in China, North Korea, Russia, etc. This step is critical because it identifies what communications may already have been intercepted by those actors and whether it's safe

    So we have the federal government trawling through huge amounts of encrypted data and messages. Working hard to develop increasingly powerful techniques for decrypting private data. And bringing the resources of a nation state to bear to do it.

    All of this largely in the service of a drug war that has been an abject failure.

    Legalize all drugs. Treat the hard stuff as a medical condition. Don't allow the hard drugs to be sold by private companies because we can't trust private companies with something that deadly and dangerous. Take the savings from the drug war and spend it on addiction therapy.

    That last one is the hard part. Everyone agrees we should do it but when it comes time to do it drug addicts or some of the most horrible people you can imagine having been changed by their addiction in bad ways and it's really hard to get people behind treating them humanely and spending what seems like a lot of money on doing that. Never mind the fact that there are just some drug addicts who are never going to kick the habit fully and we end up just kind of supporting them. It's still way way less money and way better than the drug war but it feels really awful in a sort of lizard brain way

I'd rather have thugs on every street dealing than big corporations with advertisers, lobbyists etc. Private sales on the black market is not good and organized crime is worse but on the open market as legal business it would be on a whole other level. They already push known drug problems for a decade or more before government finally does something about it. Plus nobody would go to jail at all... except maybe some whistleblowers.
