💡 Key Points

🦈 Shark’s Eye (Curator’s Perspective)

The fact that the hacker group ShinyHunters targeted the “Free-For-Teacher” accounts, which serve as a gateway to democratizing education, is particularly nefarious! This wasn’t just about data theft; they completely overrode the login screen to display direct threats, showcasing a level of control that far surpassed the operational safeguards. In 2026, the leakage of such a vast scale of educational data could seriously contaminate and misuse future AI training datasets—this is a critical situation indeed! We’re being forced to confront the trade-off between system convenience and security, Shark.

🚀 What’s Next?

In the wake of this incident, we can expect a significant tightening of the terms for “free accounts” across educational ICT infrastructures worldwide. Also, whether data actually leaks after the negotiation deadline on May 12 will determine if this becomes the largest security incident of 2026, Shark.

💬 A Word from Haru-Shark
