In July this year, shortly after students sit down for university exams in Sydney, an image of the exam paper appears on the Chinese social media platform RedNote. Multiple outlets report that the leak spreads online within seconds of the exam starting, raising concerns about how the paper may be obtained and shared.

The articles describe claims and speculation about the methods that could be used to capture exam questions discreetly. Reported examples include “cheating jackets,” button cameras, and very small “rice-sized” earpieces, alongside broader discussion of how such technology could be used to transmit information during assessments. Outlets focus on the apparent speed of the leak and the implications for exam security.

While the reporting centres on the same incident and online posting, the emphasis varies. Some coverage highlights the timeline of the RedNote appearance and the potential vulnerability of exam secrecy, while other parts focus more on the range of concealment technologies being discussed publicly. None of the sources provided here establishes definitive responsibility or confirms the exact mechanism behind the leak.
