The team behind the game NIKKE posted that its PC launcher's script files may have been tampered with by a third party; they pushed a fix and say they're looking into how far it reached. We see it as a good reminder for anyone with a browser wallet: everything you install runs on the same computer as your keys, including games, launchers, mods and extensions. We recommend keeping long-term keys in an offline cold wallet, away from the machine you play and browse on.
