LOL. Can't believe everyone here, I mean HERE, where people are much smarter than in ordinary discussion groups, still haven't notice this is a PR stunt.
Check out the "demands". They just want to expand the player base. Expanding the player base is something that publisher would want, not hackers. Another thing they want is adding RU-localization (which again enables expansion of the player base) and reinstating a Discord channel, which advertises the game, bringing even more players.
Does it look to anyone those are enemy hackers? To me it looks like the publisher "hacked" themselves. To get free PR in various media outlets, including TechSpot.
And what's the punishment if those "demands" aren't met? Did they encode their data? Will they delete their disks? Did they insert random errors everywhere, so that automated backups get contaminated over time? Nope.
The "punishment" is to release gigabytes of PR material from the game, so that game attracts even more interest, and gets advertised in even more media outlets. And then the western player base, angry at the hackers, would buy even more copies in spite.
Come on people, have you never heard of guerilla marketing? Well, now you have. But I didn't expect it would fool the audience on TechSpot.
