Oh, and the core of the UK government runs on WhatsApp https://www.theguardian.com/uk-news/2023/jun/02/senior-torie...
Wow, I'm surprised a government IT would allow this. Any corp I've worked for strictly prohibited use of messaging tech that's not self-hosted.
That makes me wonder, what _do_ governments around the world use for p2p communication?
I'm sure the business profited greatly from that...
And right now you look can look all the big MoveIT mass exfiltration hitting a wide range of orgs that wouldn't use Sharepoint "for security reasons".
Employees did not like it and after a few months everyone migrated to Whatsapp.
See this movie's footage for Afghan Army usage: https://www.rottentomatoes.com/m/retrograde_2022_2
The Ukraine has/had a relevant IT-offshoring sector, from Wikipedia there's around 1/3 of the soviet military industry that was sitting there (including companies like Antonow)... and they had a few years of preparation since the krim was occupied where they knew that russian secret services would try to undermine any kind of communication infrastructure.
I doubt that they currently rely on WhatsApp for military communication...
Edit: But thanks for the information :)
