Good morning,
When trying to access the CISCO DEVNET Sandbox, Catalyst 9000 Always-On Sandbox -20260728T10175593, using the I/O credentials, I do get:
Wrong Credentials. Please Login again.

If you're using the correct I/O credentials, try waiting a few minutes in case the sandbox is still initializing. If it still fails, verify you're using the credentials for that specific sandbox and contact DevNet Sandbox support with the sandbox ID.

This is while I am accessing directly the Catalyst 9000 Username as per example, the sandbox it self is functional, please check the snip that I have added.
Thank you!

The shared instance hostname is now "PWNED-BY-WINTER" I'm gonna go out on a limb here and say the system is compromised.

I asked the sandbox team to reset the "Catalyst 9000 Always-On Sandbox". Given this is a shared resource, some users remove the mgmt/auth config resulting in the lost of the device. There are checks in place, but seems they need to be improved.
I dont consider these instances are compromised when we provide the admin credentials for users to test.
