Re: It's all in history
"China, for all the punch lines they have become, aren't stupid."
That whooshing sound was the point flying above your head.
China is so RIDDLED with attackable systems that it's used as the jumping off point for attacks on the world _BY_ the world and its dog (especially the Unicom network)
Very few of the attacks coming FROM Chinese network space have actual honest to goodness Chinese origins and this is compounded by the same mentality that sees train crash carriages hastily buried in trenches complete with victims inside, or doctors reporting the beginnings of a Coronavirus outbreak arrested and charged with public order offences - public officials not only utterly refuse to acknowledge they have problems, they actively shoot the messengers, so things don't get fixed until there's a massive clusterfuck already in progress.
Militaries tend to cooperate with each other on international basis' a lot more effectively than civil police groups do - even notional "enemies" do, mainly because they can't afford for mistakes to get out of control - which means that tracking down organised crime gangs would be a lot easier - and those gangs are a lot closer to home than you realise. Follow the money.
Police investigation of "cyber" anything is getting better but they're hampered by the noxious habit of putting their hands up in the air and dropping it in the too-hard basket as soon as it crosses a border instead of seeing where the rabbit hole leads. (Bury St Edmonds in one case, and that only got enthusiasm because the twit in question targetted the police themselves)
