Ukraine's current hacking of Russian TV: There's been a lot of engagement with my🧵below (thanks everyone!) so here's a new🧵with more details:
- Ukraine is uplinking its own multiplex (a "mux") to various Russian satellites, mimicking the mux being uplinked by Russia
2/ The Ukrainian uplink is much stronger than the Russian one, fooling the Russian satellite into relaying the Ukrainian uplink instead
- Ukraine has also given the individual TV channels on the "fake" mux the same IDs as on the Russian one
3/ This means the terrestrial transmitters in occupied parts of Ukraine have also been fooled into relaying the Ukrainian broadcasts as if they were Russian ones
- Here's evidence from within occupied Ukraine of what viewers have been seeing on their TVs
4/ One viewer in occupied Ukraine said: "I don't know how our [guys] hacked the Russian channels, but we were beside ourselves with happiness. We watched the president's address and cried. It was something incredible! We are grateful to those who did it!" facebook.com/oleh.baturin/p…
5/ A Russian official blamed the hacking on information warfare conducted by Ukrainians "under the guidance of Anglo-Saxon IT terrorists". t.me/alexandr_malke…
6/ For days, the Russians have been frantically changing their satellite TV configurations, moving around the frequencies they're using to transmit to occupied areas of Ukraine. They're now using multiple satellites & frequencies in a bid to outwit the hacking and gain resilience

🧵80 years ago today! A milestone in information warfare as Britain's secret "Aspidistra" radio transmitter is launched. Its first task is to support Operation Torch, the invasion of North Africa. Its signals are so strong that listeners in Morocco think it's a local station. 1/n
In fact, Aspidistra was in a large hole in the ground in Sussex. Operated by the Political Warfare Executive (PWE), it relayed the BBC's French service that day, airing messages by Roosevelt, Churchill, Eisenhower and De Gaulle in support of the allied landings. 2/n
Aspidistra could easily hop from one channel to another, and PWE also used it during Torch to take over the frequency of a Vichy-controlled station in Rabat. But they didn't tell the British Admiralty, who heard the broadcast and assumed the city had surrendered. 3/n

A long and nerdy thread about two obscure incidents in the Afghanistan war:
Big history is made up of millions of small mistakes that go unnoticed by those who make them.
This thread is about two of the tiniest of such errors, from US information operations during the war. 1/17
The first story:
When the US invaded Afghanistan in October 2001 it aired radio broadcasts in local languages for the local population. 2/17
The recorded broadcasts were transmitted from Commando Solo EC-130 aircraft.
Leaflets were dropped, giving the times the station was on the air – 5am to 10am and 5pm to 10pm – and the frequencies to hear it on: two on AM/mediumwave (864 & 1107) and one on shortwave (8700). 3/17
