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?
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".
I'm sure the business profited greatly from that...
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 :)
