The Universidad Nacional Autónoma de México (UNAM) filed a criminal complaint alleging widespread fraud during the 2026 undergraduate admission exam.
The integrity of the selection process is critical because the fraud could jeopardize the academic futures of thousands [1] of prospective students. If the results are compromised, the university may face challenges in maintaining a fair and merit-based entry system for its highly competitive programs.
Investigators believe the fraud involved several sophisticated methods to bypass security. According to reports published earlier this month, the university detected instances of identity theft and the use of unauthorized consulting services [2]. These services allegedly operated networks of deception to alter exam responses and secure placements for specific candidates [2].
Furthermore, the university cited the unauthorized use of artificial intelligence tools as a contributing factor in the breach [2]. The combination of AI and identity impersonation suggests a coordinated effort to manipulate the testing environment, a development that has prompted the institution to seek legal intervention through a formal criminal complaint [3].
UNAM has issued warnings to applicants regarding these fraudulent schemes. The institution is now working to determine the full scale of the infiltration to ensure that legitimate students are not unfairly displaced by those using illicit means [4]. The university is coordinating with legal authorities to identify the individuals and organizations behind the consulting services and AI-driven fraud [3].
“The university detected instances of identity theft and the use of unauthorized consulting services.”
This incident highlights a growing vulnerability in high-stakes academic testing as artificial intelligence becomes more accessible. By filing a criminal complaint, UNAM is signaling that it views AI-assisted cheating and identity theft not merely as academic dishonesty, but as a legal violation. The outcome of this investigation may force universities worldwide to redesign entrance exams to be more resilient against AI and digital impersonation.
