Per article, Oracle has hastily rebranded the breached service as "Oracle Classic", for the sole purpose of being able to claim with a straight face that "Oracle Cloud" was not impacted.

The hacker has demonstrated that they have/had write access to URLs under login.us2.oraclecloud.com. It's incredibly disingenuous on Oracle's part to claim that this is not "Oracle Cloud".
