@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...

• Bonis points if that device has a freely reprogrammable #IMEI to allow hiding it's identity.

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.

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.

@AmbianceAsunder I mean, given the listed sample of a state-sponsored attack, we can assume the attackers have some basic project management skills and being able to collect both #OSINT and mobilize local assets to collect #SIGINT on street level.

• Not to mention none of the revealed info indicates they could've done it with like #OpenStreetmap / #GoogleMaps and a simple #notepad at hand.

After all, they most likely only realized that #WiFi-connected / authenticated devices are exempted by having collected #INTEL on the targeted org's employees and their workflows.

• Making me conclude they had access to employer handbooks and IT documentation via a unclassified employee. But they couldn't risk have said #insider / #UC blow their cover by i.e. smuggling in an unathorized #device or sth.

It would however make sense to have someone inside as a #canary even if they ain't in #IT nor have any privilegues…

• After all, depending on the organizational size it's a statistical inevitability to have privileged access...

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!

Btw the cmd to get only °c is

$ rtl_433 -C si

ALL YOUR SENSORS ARE BELONG TO US!

</diabolic laugh>

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.
