Discord account hacked

Well, a few weeks ago I wanted to download a game from Internet Archive called "Nekomew's Nightmares." When I opened the app, it opened a setup wizard installer for the game. When the installer finished, it put the game on the desktop. I opened it and the game seemed perfect, normal, but the next day I got a surprise: I received an email from Discord saying that my account password had been changed. I checked and it was true, I couldn't access my account. I also received another email from Steam, and I couldn't access my account either... Be careful when downloading games from Internet Archive...😔✌️🥀
