This paper presents the model of a robot software capable of doing
some functions inside the online role-playing game Tibia automatically
while avoiding the Battleye anti-cheating system and show
countermeasures that can help Battleye and Tibia developers, as
well as developers of similar games to prevent this type of bot from
surpassing their anti-cheating system. Among these functions are
the hunting, the healing, and the looting. Specifically, there is an
explanation of the game’s mechanics and how the robot surpasses
the anti-cheating system by analyzing the game screen and simulating
mouse and keyboard functions, without doing any memory
injection or memory reading. The evaluation of the bot was done
during six months on ten accounts with different variables such
as the character’s vocation, daily playing time, account status, and
whether the character is hunting in the same place every day or
variation occurs.
