This mod is a trojan, called AgentTesla. It will hijack your computer and allow an attacker to complete their own actions, DO NOT, download this mod off of Thunderstore Mod Manager. The mod also DOES NOT depend on any other mod, yet if it were a REAL mod, it would depend on MelonLoader and ModThatIsNotMod, or at least the first one, to be allowed and working on Thunderstore like a normal mod to the game.
