This contest takes place simultaneously in high schools across multiple countries. The individual proctors should be responsible for monitoring, but clearly they failed.
When I did it (nearly 20 years ago) we couldn’t use online resources at all. No Google, no Stack Overflow. Our proctor was there to ensure we didn’t cheat.
This isn’t about how good you’ll perform at a job, it’s about your knowledge, ability to design, and critical thinking skills.

Maybe the idea of a distributed international competition just doesn’t work anymore. It’s either too hard to proctor, or teachers are willing to help or let their students cheat in order to have an advantage.
