You download "RSS_F1_2025_CRACKED_VERIFIED.rar." Inside is a steam_api64.dll that is not a crack, but a password stealer. Within 24 hours, your Steam account is sold, your Discord is spamming crypto scams, and your saved passwords are compromised.
Furthermore, many "paid mods" are actually stolen (ripped) from Forza, Gran Turismo, or rFactor 2. Cracking a "rip" is double-piracy. You are stealing a stolen asset.
Unlike cracking Forza Horizon 5 or iRacing , which is clearly illegal, AC mods exist in a legal grey zone. Mods are derivative works of Kunos’ intellectual property (the game engine). However, mod creators argue they own the 3D models and physics data.
