"Always Free tier" compute disappeared with awarning email

My free tier compute has been disabled and I received an email saying:

"Oracle has received notice of or detected unusual and potentially harmful activity originating from your tenancy."

Reason:

Traffic Details: Outbound Port Scanning, Brute-forcing, Web Exploitation, and/or DDoS

I think it may have been a WireGuard docker stack I installed recently.

I need help/suggestion on what I should do now to continue using oracle cloud.

Do I need to delete my account and recreate it?

I would appreciate any form of help or guidance on this.

Thank you in advance.
