Communication applications and social media sites serve as a platform for users to distribute information and connect to other users, potentially allowing perpetrators to perform antisocial behaviors. The current study examined the relationship between Dark Tetrad of personality (i.e., Machiavellianism, narcissism, psychopathy, sadism) and antisocial cyber-behaviors (i.e., cyberbullying, cybertrolling) by surveying young Malaysians (n = 323) aged from 18 to 26. Partial least squares structural equation modelling (PLS-SEM) revealed that Machiavellianism was not related to cyberbullying and cybertrolling, while narcissism was positively related to cyberbullying but not related to cybertrolling. Meanwhile, psychopathy and sadism were positively related to cyberbullying and cybertrolling. The results of this study contribute to the cyber-behaviors literature, knowledge about the antisocial cyber-behaviors in Malaysia, supports sadism as a dark personality and the study acts as a reference to minimize these behaviors.

通信应用程序和社交媒体网站作为用户分发信息和连接其他用户的平台，可能允许犯罪者进行反社会行为。目前的研究通过调查 18 至 26 岁的年轻马来西亚人（n = 323），研究了人格黑暗四联体（即马基雅维利主义、自恋、精神病、虐待狂）与反社会网络行为（即网络欺凌、网络攻击）之间的关系。部分最小二乘结构方程模型（PLS-SEM）显示，马基雅维利主义与网络欺凌和网络喷子无关，而自恋与网络欺凌正相关，但与网络喷子无关。同时，精神病态和虐待狂与网络欺凌和网络拖钓呈正相关。
