It seems Amazon has facilitated the sale of some pirated games on its storefront.
As was first noticed by Reddit and ResetEra users, Frostpunk and Surviving Mars were being sold on Amazon for just a few dollars. Seeing as these games usually cost $30 and $40, respectively, users suspected something was off. Redditor CodependentWealthy discovered that the sellers had stolen the GOG versions of the games and repackaged them with their own suspicious installer signed and published by “Ace Media Group LLC.”
