Well the Russian government cares. This hack probably disrupted their shipments of military gear and supplies to Ukraine for about a week.
BTW --- are you using YaBrowser or Chrome? These are the only two browsers that would have let you play Pac-man on their hacked website. Admittedly the website has been restored at this point to the proper corporate image.
Note the article is a day old (August 23rd). The hack took place on the 21st or 22nd.
Yeah, Chrome. The company should put Pac-Man up there now as a permanent feature, since Russians are too-damned serious and stodgy They need to lighten up, what with all this killing people next door and shit.
