Russian Spy Satellites Have Intercepted EU Communications Satellites (arstechnica.com) 85

European security officials believe two Russian space vehicles have intercepted the communications of at least a dozen key satellites over the continent. From a report: Officials believe that the likely interceptions, which have not previously been reported, risk not only compromising sensitive information transmitted by the satellites but could also allow Moscow to manipulate their trajectories or even crash them.

Russian space vehicles have shadowed European satellites more intensively over the past three years, at a time of high tension between the Kremlin and the West following Moscow's full-scale invasion of Ukraine. For several years, military and civilian space authorities in the West have been tracking the activities of Luch-1 and Luch-2 -- two Russian objects that have carried out repeated suspicious maneuvers in orbit.

Both vehicles have made risky close approaches to some of Europe's most important geostationary satellites, which operate high above the Earth and service the continent, including the UK, as well as large parts of Africa and the Middle East. According to orbital data and ground-based telescopic observations, they have lingered nearby for weeks at a time, particularly over the past three years. Since its launch in 2023, Luch-2 has approached 17 European satellites.

    So did they intercept the communications satellites, or did they intercept the communications OF THE satellites? If the latter, fix your title op.
    • It's the same click bait slop title from the Arstechnica story, nothing new from them.

    • It's a big difference. One is an act of war, the other is a radio.

      The former, which is why TFS talks about space vehicles and "risky close approaches", rather than ... whatever language might be appropriate for snooping on transmissions.

      Yes its a clickbait title.

      The US also does this - check out the Orion/Mentor satellites, or the JUMPSEAT satellites. Public astronomers have tracked satellites launched by US launchers moving into position behind other countries communications satellites, where they can capture the overspill of the transmissions sent to those satellites - they have huge dishes for just that purpose.

      But oh noes, Russia or China is doing it, must call them out on it!!

        Yep, terrible headline for something we know has been happening since we started forming governments. Their spies spy on us, our spies spy on them, their spies are spying on our spies spying on their spies spying on our spies spying on us.

        The big question is how successful they are at it? Russia has traditionally been quite good at spying but that's because they were able to find people to turn easily, techwise they usually couldn't get anything working.

    This sounds quite sinister and James Bond-ish. Is Ernst Stavro Blofeld behind the satellite interceptions?

    But when we read the article we see things like this:

    European officials believe Luch-2 is a signals intelligence 'interceptor' and are concerned that sensitive, unencrypted information is being accessed by Russia.

    What the actual fuck?! If it is sensitive information, then why is it unencrypted?

    I'm going to have to assume that the fault here is in the article's author. They have to have fucked up the details. Surely, European officials aren't that fucking stupid.

      Surely, European officials aren't that ... stupid.

      We hope.

    • exactly - satellite communications intercept is not the big story here... if the Russians care to make a big effort to intercept they likely know that at least some of the sensitive data isn't sufficiently well encrypted that it becomes interesting to capture.

    • A $32million dollar Reaper drone also had unencrypted video feeds for quite a while.

      What the actual fuck?! If it is sensitive information, then why is it unencrypted?

      There's a difference between "Spy on South Moscow at 3pm" and "Our King is in the Epstein Files."

    • What the actual fuck?! If it is sensitive information, then why is it unencrypted?

      Because it's very old, and non-military.
      It really is unencrypted.
      The sensitivity of the information is in that the command and control protocol can be derived since it's in the clear, and the satellites can then be maliciously commanded. Right now, there's really only a threat of a state actor doing this, so it wasn't a huge concern.
      I don't find this that strange for an old GEO sat.

      • Note that things like Facebook were not encrypted either until surprisingly recently.
        • The last study I saw said 50% of sats in GEO used unencrypted command-and-control channels, protected by nothing other than tight radio cones, which is probably mostly sufficient for most purposes (any ground-based interference is going to be under domestic jurisdiction) but is obviously usless for a state actor puttering around GEO.

    With America shortly after Trump was elected because it kept getting leaked, again.

    So I have no doubt that Russia is going to have to start going back directly to the source to get intelligence information on Europe. Since their asset can only do so much.
    • Europe restricted the sharing of intelligence with the US.
      In point of fact- they always have, and vice versa.
      The amount of restricted intelligence is higher than it used to be, and Trump's volatility is a factor in that for sure, but they're not idiots. They know what kinds of things to be concerned about leaking, and what things not to be.

      I believe that Israel would have done that as well, given the new found love that Trump has for their topmost enemies - Turkey and Qatar. Even if they're working closely w/ the US when it comes to Iran

    So what? It's not like the west doesn't try to intercept russian signals. So stop being such a hypocrite, and just make sure you have better encryption.
  • "sensitive information—notably command data for European satellites—is unencrypted, because many were launched years ago without advanced onboard computers or encryption capabilities."

    Pretty surprising that the command data isn't encrypted, that's a severe vulnerability. I don't know how old those satellites are but it wouldn't take a very "advanced onboard computer" to implement some basic encryption.

      It's not just flying decent compute -- it's flying *hardened* decent compute and though it seems things are changing, there has been a big gap between what's certified for onboard processing v. the current state of the art: there's a lag in raw performance due to all the hardening that needs to be done. Hard to replace a processor in geosync orbit: they need to be built to last, reliably. Still, shame on those that brought us such regulatory gems as GDPR to not be encrypting their comms.

        Cryptographically secure communication was a thing 30 years ago. In fact SSLv1 is 30 years old and ran fine on 90s computers. Stuff that went into space 25 years ago could have and should have had this capability.

          The person managing the budget couldn't figure out why cryptography was important, so it was shelved. Nepotism strikes again.

        • Cool. Rad hardened CPUs were way slower than their desktop counterparts.

          Every version of SSL from back then has been pwn3d so hard that it may as well be in clear text.

    TFA says Intelsat39, launched in 2019, is a "typical example." And I think they mean a typical example of a satellite "launched years ago without advanced onboard computers or encryption capabilities."

    No crypto in 2019? I know these things are planned and designed many years in advance, so they might contain dated components, but even so... wow.

      The Lanteris 1300 [wikipedia.org] satellite platform dates back to the 1980s. It has been updated several times since then, but it is unclear how much they changed or whether they fixed design flaws like that. I could very easily see a 40-year-old satellite design not using encryption.

      • Plausible; but in that case, you would do what you could to avoid using that platform for "sensitive" data, right? Mundane stuff, sure; no big deal. Confidential stuff: no.

          For communication *through* the satellite, the communication platform just passes data. The data can be encrypted whether the communication platform supports encryption or not. An Ethernet cable doesn't support encryption either, and no one cares.

          The issue is communication *to* the satellite — commands to, for example, tell it to move to a higher or lower orbit, to change which way its antennas are pointed, or to begin a de-orbit or graveyard orbit burn. They're saying *that* is not encrypted. If true, then it's not that the platform can't be used for sensitive data so much as that you can't trust that someone won't inject their own signal and tell it to launch itself into a graveyard orbit 200 miles higher up and render the satellite useless, to power down all of its transponders, or to crash into a nearby satellite.

          If true, that's deeply disturbing. It seems more likely that there is some encryption, but that it is weak or thoroughly broken.

    • Why would the satellite need crypto chips to recieve encrypted stuff if it's just supposed to send the same signal back in a different trajectory? Are they supposed to have some sort of compute facility on the satellite so they have to decrpt, do stuff to the data, encrypt and transmit?

      If the commands to the satellite are also encrypted, they can just have a lower capability chip to decrypt the commands. Presumably commands to the satellite will not exceed 1kbps or so line rate(fire thruster X for Y secs a

        My whole point is that if the article is to be believed, then as recently as 2019 (!?) they didn't have even this "lower capability chip." If we were talking about 1959, I'd understand, but 2019? You and I can theoretically order that satellite to turn on a thruster?! That's amazing.

  • Welcome to the club Russia. We've been intercepting satellites on a full time basis since the ECHELON project.

Fundamentally, there may be no basis for anything.
