China,Russia,Brazil think of exploits and exploitation techniques as wares to keep or use as weapons.There is not much sharing or exchange of ideas.
It's the one place where you can get clean, good Adobe CC shit conveniently packaged in a good old Master Collection format.
Torrent forums without the ridiculous ads and popups.
The only place I could find firmware hacks for various hardware including some brilliant mods for SFP routers and washing machines.
There still seems to be a sense of solidarity although I don't really like it since it's the old "fuck them all western shits".
Chinese net pops up every now and then. It's just hard to navigate, hence it's very much unknown to western users. But I know there's troves of cool stuff there.
The Chinese, Russian, and Brazilian states see exploits mainly as weapons. As does the US state....
The question is whether a hacker culture apart from state control exists, of hackers interested in ideas for their own sake/the challenge/the lulz. Without being in those scenes or even speaking those languages, I couldn't say. (But maybe you have knowledge?)
As in above parts of these comments, threads where people wonder if the corresponding cultures in the USA have been entirely "neutered" by state and corporate involvement, the question is not irrelevant to the US or European or English-speaking worlds either.
The scene is motivated by self interest and is afraid to lose exploits/techniques that they can trade for $$$ and power.
