@bob_zim @micahflee @heiseonline @golem Makes sense.
- After all, the whole #IMSIcatcher system can be detected by passive #SIGINT as it's an active attack on mobile networks.
I wounder if I can get a compatible device in #Germany as well...

Decorated WW2 code breaker Betty Webb has died at the age of 101. She spent her youth working at Bletchley Park deciphering Axis messages.
1/2 @mattblaze @ai6yr the
#Russki_SIGINT longread is now out, gentlemen and it caused quite a stir, as the notorious Russian spy satellite Olymp-K2 suddenly came drifting into the segment of our research [0° to 15° east] . Special sort of #SIGINT sat performing dangerously close approaches to intercept the satellite bus *steering commands* of the Eutelsat teleports. All sat targets of the Vienna station included.
Had to compile a thread in English over there...
While I'm no longer in the IC and can't confirm my suspicions, I simply don't think it's that plausible that everything is flowing as normal in Five Eyes. I can see why people would *say* it is. But an American intelligence & CI apparatus run by malicious, compromised kooks Gabbard, Patel, Ratcliffe, Trump, is one you need to put strong filters on, going both ways. #FiveEyes #intelligence #SIGINT #HUMINT

@jt_rebelo @mastodonmigration @GottaLaff I'd call #Ukraine "criminally incompetent" if they didn't already leverage domestic #Fiber & #GSM networks as well as procuring entire transponders for exclusive use.
I couldn't confirm X-Band use with either #XTAR or #BwSATCOM-2 simply because I have neither teleport access nor matching LNBs/BUCs ready, but existing press releases by @Bundesregierung & @AuswaertigesAmt hint that Ukraine has been upgraded to #NATO #Link22 capabilities.
Existing #SIGINT & purchases show huge amounts of COTS #KuBand & #KaBand and even #Cband-Equipment being used since 2022, which use higher-ping #GSO|s but are easier to decoy and protect against #ElectronicWarfare and #Sabotage (just by shoving the dish into a partially buried sewage pipe, making it look like a ghettohacked Copy of #BARS, the Soviet-Era #Troposcatter CnC Radio...

Yeah...
Whilst I am not a fan of #AI which I think will in the long run, will be detrimental to humans, I am far from the "AI Slop" luddites.
But when #deepseek killed their web login a few days back. I was extremely sceptical of loading the app on my device.
Thank you for doing the gods work and verifying my concerns.
I think the #Australian #sigint mob might have done a similar analysis because only a couple of days ago they issued a directive banning it off Government devices.
The Webby interface was under constant DOS attacks, so that might have accelerated app only deploy.
A good 8-minute summary of the #SIGINT situation in #Vienna, based on @harkank's investigation, has been published by @materie (a journal affiliated with the Austrian NEOS party): https://www.youtube.com/watch?v=CddUToKXZJ8
Tuning the local KiwiSDR and found this interesting signal at 6942.347 USB give or take - a little bit of research on the Signal ID Wiki convinced me that it's "Link-11" or "ALLIGATOR" or "STANAG 5511".
https://www.sigidwiki.com/wiki/Link-11
On the Signal ID wiki, specifically Link-11 CLEW at 2250 bit/s, described as PSK modulation.
At 12:29 in the podcast, there’s info about a specific encrypted German Police message - transmitted in #Morsecode during #WWII - which was intercepted by the #ChicksandsPriory #Ystation - then forwarded to #BletchleyPark for decryption - through which the Allies heard ( for the 1st time through #SIGINT ) about horrific mass killings of Jews that were happening across Europe at the time. #RAFChicksands #ChicksandsRAFB #Chicksands #WWIIhistory #MilitaryIntelligence #SignalsIntelligence #Holocaust

None of these 3 large dishes is active. Same with dish 4 in the back, this one is for the Ku band. Dish 1,2 and 4 are equipped with skew angle gear & motors to squint into downlinks.
C-Band modules - LNCs, filters & c - are all from Nortel Canada. The Ku band modules are from Swedish Microwave.
Vienna is by far the largest and one of the few remaining #SIGINT stations in EU on Russki embassies.
Tech staffers were all kicked out except here
And meanwhile we have sort of re-engineered three of these four-meter dishes and identified their targets. All three are C-band dishes and there are not that many C-band sats around any more in the segment from Greenwich to 15°.
Posted a thread on this lately, always fediverse first, and I'm currently doing a longread for a magazine here.
tl;dr: They are collecting signals intelligence mainly for their African putsch politics

Ah ok, different network., rremember. As you mentioned thíngs going unnoticed in plain sight. Everybody passing by the Russian embassy to the UN in Vienna could see 4 large dishes on top. Nobody cared what they might be doing there for years .
Late in 2022 we shot the roof with zooms & sent a drone up. Voilà: a full blown #SIGiNT station with a dozen dishes. And the NSA watching them from their "stateroom" hut above the nearby US embassy to the UN.

This is wy I have been doing much more of nearfield #SIGINT here.
More phun. Seen this ongoing 433 MHz ISM bsnd thread below?
They are secondary users with fuqing 100 milliwhiskeys and we are not. This is our band, companero.
Next to come: oil tank level indicators, house control and alarm sstems, rolling code keys of various cars.
Plus an indoor marihuana grow room system in the hood where I am stuck
I’m listening to “Secret History of World War II, The: Spies, Code Breakers, and Covert Operations,” by Neil Kagan and
Stephen G. Hyslop, which is free with my #Audible membership until December 31st. Excellent book with a lot of information I had never learned about before, including intelligence leaks by the Allied forces that could’ve truly been catastrophic had they been exploited. #History #MilitaryHistory #MilitaryIntelligence #SIGINT #MilitaryCommunications #WWIIhistory #AudibleBooks

Für die Wien-Bubble hier, eine sehr interessante Anzeige. Von diesem Loft schaut man nämlich direkt auf eine bestimmte UN-Botschaft mit gewissen Schüsseln in Wien 22 hinunter.
Eventuell interessiert sich ja wer für diese schöne Wohnung und mag sie in Begleitung einer Kamera besichtigen?

Here comes Fordie. Tyre pressure monitoring says at least one of the tyres is okay. And: Fordie is on the move so we possibly won't be seeing him again.
Good luck to your other 3 tyre sensors and watch out on the road!

well at least these shitbroadcasting on 433 MHz.
These are all weather stations and affiliated outdoor sensors all blaring out data on 433.920 MHz. No idea who owns these - yet.
Next we got to change this Fahrenheit mess to Celsius. And there are other sensors around, thankfully.
This is my provisonal shack sporting the slimmest possible set up. A 5 Watt VHF /UHF handheld transceiver connected to OE5XFK in the Mountains of hell, as everybody should know meanwhile.
The fat USB stick is an #rtlsdr, a tiny software defined radio attached to a laptop running #ubuntu #linux 24.04.
And now we go a-hunting, Nearfield #SIGINT starting with a humble bash proggie.

And there she is in the dizzy light of the winter sun. A stern, prickly beauty throning high above smalltown suburbia. As you might have noted there is this usb black stick in front.
A SMB-socket on one side, on the other USB, so this might well be called a transgender stick. Linguistic/psychoanalytic sidenote: Even phallic verticals are grammatically female in most languages.
What for a start? Humble nearfield #SIGINT in an environment, I had the displeasure to come of age.
