Gamers are being duped into helping hackers become rich, after downloading cracked games laced with hidden malware. Versions of Grand Theft Auto V, NBA 2K19, and Pro Evolution Soccer 2018 are being given away free in forums. But hidden inside the code of these games is a piece of crypto-mining malware called Crackonosh, which secretly generates digital money once the game has been downloaded. Criminals have made more than $2m (£1.4m) with the scam.
