@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".

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
All the best for 2025 @duncaned! Hopefully you are fine.
