Those attacks are real on our platform. There are teams around the world, that have build servers on our platform and attack each other while defend their servers. It shows you who attacks whom.

Can those servers act as honeypots and attract real attacks too?

No! Not that it can't but because not this is its primary scope. It act like a private network where you can connect via VPN and start practice your hacking skills against real users and servers and not "vulnerable by design" ones as you find in any traditional penetration testing lab.
