A global surge in fraudulent research papers, exceeding 10,000 retractions last year, has become an international scandal. Originating in China, the issue has spread to other regions, with "paper mills" producing fabricated studies. Bribes to editors and infiltration of fraudulent agents exacerbate the problem. Major publishers are taking action, but financial incentives for researchers to publish persist. The escalating prevalence of sham science is eroding the foundation of trustworthy scientific knowledge, prompting calls for systematic solutions to address this growing threat to the integrity of research.

In the book "Corruption in Higher Education: Global Challenges and Responses," 34 experts shed light on various corruption issues in higher education: contract cheating and outsourcing assignments; ambivalent hiring processes; fake universities that take various forms, from profit-driven schemes to students buying degrees without fulfilling obligations; corruption research involves scholars, administrators, and agencies, united against academic corruption. Future steps include integrity theory development, examining secondary education's impact, leveraging technology, avoiding social group stigmatization, and fostering global cooperation.

According to 10 Ukrainian scientists, plagiarism, pseudoscience, bribes, and cheating are some of the big threats to academia in Ukraine. Around 90 percent of all science professors in Ukraine are not legitimate researchers. A study of undergraduate students in the Ukrainian city of Lvivs shows that 93 percent of students reported that they had plagiarized schoolwork and 48 percent said they had paid bribes at their university.

Academic corruption exists in doctoral education even though this should reflect the highest standards of academic integrity. Doctoral degrees have become especially popular among politicians, state bureaucrats, civil servants and people seeking employment in academia. An entire market has formed in Ukraine that offers ghostwritten dissertations to order. This market consists of not only individuals but also officially registered firms. If in 2009, there were 16 such firms, by 2016 the number tripled, reaching 46.
