- T-Mobile backhaul: Users' SMS, voice call contents and internet traffic content in plain text.
- AT&T Mexico cellular backhaul: Raw user internet traffic
- TelMex VOIP on satellite backhaul: Plaintext voice calls
- U.S. military: SIP traffic exposing ship names
- Mexico government and military: Unencrypted intra-government traffic
- Walmart Mexico: Unencrypted corporate emails, plaintext credentials to inventory management systems, inventory records transferred and updated using FTP
This is insane!
While it is important to work on futuristic threats such as Quantum cryptanalysis, backdoors in standardized cryptographic protocols, etc. - the unfortunate reality is that the vast majority of real-world attacks happen because basic protection is not enabled. Good reminder not take our eyes off the basics.
>we re-scanned with their permission and were able to verify a remedy had been deployed: T-Mobile, WalMart, and KPU.
The fact that critical infrastructure (e.g. utility companies using satellite links for remote-operated SCADA) was exposed is really scary too.
Really serious security risks in critical/industrial infrastructure are ... numerous. And these aren't complex vulnerabilities, these are leaving the door open with default passwords, unencrypted traffic, and that sort of thing.
Also a fun fact: For a long time it was only semi-officially known that the BND owned and operated the site. Officially it was called "Long distance telecommunications station of the Bundeswehr" and operated by the "Federal Office for Telecommunications Statistics"
Officially it has been transferred to the BND; experience suggests all data from there still goes straight back to Fort Meade… (And in exchange the BND gets some morsels back on people _they_ are not allowed to spy on publicly.)
Oops
Another round of OpSec training
anyway, but even that had a joke of opsec.
URI's leak company secrets. I'm sure there's some people at Google using Edge which are leaking company data to Microsoft. I'm sure there's some people at Microsoft using Chrome which are leaking data to Google.
Edge and Chrome both send back every URI you visit to "improve search results" or to "sync history across devices". It's not clear if this includes private mode traffic or not (they don't say).
Huge privacy hole to allow this, and nobody seems to be aware or care.
They do have privacy policies which say they won't sell that data, or use it for advertising or anything other than delivering the service. But - who knows if that is true? There's no oversight. And if they get caught breaking that privacy policy, who has the appetite these days to do anything meaningful in terms penalties? Nobody.
> who knows if that is true? There's no oversight
The oversight is that those companies rely heavily on being trustworthy, and proving untrustworthy would be disastrous for their business models. Companies don't have to care right now because they have reason to believe Google, MS, et. al. aren't sniffing that data. If they came to believe they were?
Google alone is making $43 billion on Cloud and would prefer not to jeopardize that revenue stream.
The reason why this does not result in a significant loss of usage is because trustworthiness-usage is not a linear function or a even a continuous function -- it is a step function. To cause less usage, the loss-of-trust force has to be higher than the networking effect force. Otherwise, behavior does not change.
That's what I don't get - security and compliance people are paranoid.
This is the kind of thing they shouldn't be requiring evidence to care about, given the rest of their job is about the "what-ifs". Just seems crazy to me.
Not as insane as it was in the early 2000s…
> while link-layer encryption has been standard practice in satellite TV for decades
Before Snowden, I would say 99% of ALL TCP traffic I saw on satellites was in unadulterated plain-text. Web and email mostly.
… the pipe was so fast, you could only pcap if you had a SCSI hard drive!
SMS was also a bit like this in its early days and you could read them coming off the local cell (also true of calls at a certain time, but I didn't see much of this).
I just did a quick search and apparently many pagers in the UK are still running cleartext POCSAG! https://www.reddit.com/r/RTLSDR/comments/1asnchu/are_uk_page...
This is why NSA asked for (and got from SGI) a guranteed rate I/O API - to make sure that whstever the signal intelkigence platform sensors captured could be written to storage.
His base satellite signal was unencrypted and a main reason he used it for this purpose. Our channel was scrambled, and only verifiable after our receiver with the decoder was connected. It was impressive seeing someone that good at their job make it look so easy, but after he explained the layman's version of orbital slots it became less magical. This is why magicians are meant to not tell you how the trick is done.
Penn and Teller play a lot with that idea, for example.
Not even WPA or WEP. Just clear across the sky. And this is terrestrial.
My bet is that in space there would be a noticable increase in heat/energy if they did encryption by default. But its still incredible to see them pretend like space is impossible to get to, ultimate obscurity.
Why would it? The data originates from earth, and should be encrypted during the uplink leg too, so the crypto should all happen in the ground segment (or even well before it reached anything that could be considered part of the satellite setup, honestly).
Practically, you'll also want to be able to reconfigure spot beam to backhaul mappings or even cross-connect some spot beams to cut satphone-to-satphone voice latency in half etc.
That's not even considering constellations like Iridium that do actual packet switching in space.
I believe that’s one of the few things that even amateur radio operators are allowed to encrypt for that reason.
The reason security is so bad everywhere is that nobody gets fired when there's a breach. It's just blamed on the hackers and everyone just goes on with life singing "We take security very seriously--this happened because of someone else!"
At least here in the EU we're moving toward personal responsibility for C level's who don't take IT and OT security serious in critical sectors, but in my anecdotal experience that is the first time anything regarding security has actually made decision makers take it serious. A lot of it is still just bureaucracy though. We have a DORA and NIS2 compliant piece of OT that is technically completely insecure but is compliant because we've written a detailed plan on how to make it secure.
this must mean the consequences of such a breach has either not produced any visible damage, or the entity being damaged is uncaring (or have no power to care).
Imagine jailing doctors for every patient that died you would be out of doctors quite soon.
Eg. doctors do get sued and fired for malpractice, if they did something no other skilled doctor would reasonably do ("let's just use the instruments from the previous surgery").
- Oops! mistakenly left some instrument inside and sewed up the patient - Junior begging to do certain step of the surgery while the anesthesiologist asking them to just get a move on. - Administered a drug to a newborn baby which was supposed to be given to the mother. (My sister's colleague did this with no consequences)
There is a world of difference between "nothing happened" and being fired. Just like in the NBA, a fine (monetary penalty) of a sufficient size will get someone's attention without losing their skills forever.
Yeah lets say you were carrying unencrypted frames for Bills Burger Hut.
The largest extent of the damage might be sniffing some smtp credentials or something. Bill sends some spam messages, never figures out how it was done but their IP reputation is always in the toilet.
Lets then say instead of Bills Burger Hut, you are carrying traffic for critical mineral and food industries. The attacker isnt a scammer, but a hostile nation state. Customer never realises, but theres a large, long term financial cost because (TOTALLY NOT CHINA) is sharing this data with competitors of yours overseas, or preparing to drop your pants in a huge way for foreign policy reasons.
No one gets fired until after the worst case long term damage, and even then probably not.
In fact, the likely outcome is that the burden gets moved to the customer for L2 encryption and the cowboy never changes.
Instead we're constantly asked to sign one-sided contracts ("EULAs") which forbid us from suing. If a company's incompetence results in my data being leaked on the internet, there's no consequences. And not a thing any of us can do about it.
The disadvantage of this is that the local data protection agencies haven't been handing out very big fines. Sometimes that's due to company law. In my country you'd fine the owning company, which in many cases will be a holding company. Since fine sizes are linked to revenue and a holding company typically has no revenue, this means fines are often ridicilously small.
Now, management, control, etc? Yeah those you need to decode in orbit.
Wouldn't this still leak metadata for routing?
Anything else could be masked by metadata encryption, rotating lower layer identifiers, and cover traffic. Not sure if any actual protocols do that though.
>Encryption imposes additional overhead to an already limited bandwidth, decryption hardware may exceed the power budget of remote, off-grid receivers, and satellite terminal vendors can charge additional license fees for enabling link-layer encryption. In addition, encryption makes it harder to troubleshoot network issues and can degrade the reliability of emergency services.
So, the only suggestion that there would be greater heat/energy if they did encryption by default is the part about decryption (receiver) hardware having limited power budgets in some cases. There's more than what I copy-and-pasted above, but the overall message is that lots of organizations haven't wanted to pay the direct costs of enabling encryption... although they should.
EDIT: Link to Q&A https://satcom.sysnet.ucsd.edu/#qanda
The same could have easily been mandated for satellite links - no encryption, your packet won't get forwarded to the internet at the ground station, and any packets sent to you from the internet will be sent to you encrypted. And all this can be implementd without needing to touch the satellite itself, which will continue to forward what it sees as unencrypted traffic without any design changes. It could even have been implemented incrementally on existing running services, with old and new equipment working side-by-side, but all new ground stations required to support encryption, and with a sunset date for old equipment, and a rolling upgrade program.
DOCSIS got this right in 1999; the satellite industry has had 25 yeqrs to catch up.
> Panasonic told us that enabling encryption could incur a 20–30% capacity loss. In addition, when using IPsec, ESP and IP headers can introduce 20–30 bytes of overhead, which is nontrivial for small-packet applications like VoIP and video calls
Wow, I guess they're still betting on customers sending tons of redundant data up/down that they can shave off via compression? That's such a 90s modem thing to do. ("Faster than 56 kbit/s!!")
If you were in say, Alice Springs in Australia (wink wink) for example, you'd be able to see traffic for Indonesia, Philippines, most of South East Asia, and perhaps parts of China, South Korea and Japan if the beams are right.
location location location is an apt phrase for more than just real estate
Pine Gap is a large facility for collecting data coming down from our own satellites.
Foreign satellite collection in Australia happens at two other facilities: https://en.wikipedia.org/wiki/Shoal_Bay_Receiving_Station https://en.wikipedia.org/wiki/Australian_Defence_Satellite_C...
