Plagiarism as a type of cheating in theses is prevalent in higher education institutions. Academic fraud frequently occurs in the bachelor's, master's, and doctoral levels of education. Cheating in student thesis papers is escalating out of control and is tough to eradicate. This study aims to identify the sources of academic dishonesty in the form of plagiarism, as well as the attitudes of students towards it. This study employed statistical variables (mean, standard deviation, minimum, and maximum) to determine the sources of student plagiarism in 54 thesis reports. Subsequently, Google forms were used to send online questionnaires to determine students' attitudes toward plagiarism. 54 non-semester students from the academic years 2020, 2021, and 2022 participated. Internet-based sources were screened with Turnitin for instances of plagiarism in thesis reports. Yet, student publications and papers were not the most often plagiarized sources. In addition, the findings of this study demonstrated an unfavourable attitude toward plagiarism. This suggests that students have a strong knowledge of the need to avoid plagiarism.
