Oracle denies it was breached after a threat actor claimed to be selling 6 million data records allegedly stolen from the company’s Oracle Cloud federated SSO login servers.
“There has been no breach of Oracle Cloud. The published credentials are not for the Oracle Cloud. No Oracle Cloud customers experienced a breach or lost any data,” the company told BleepingComputer.
This statement comes after a threat actor known as rose87168 released multiple text files yesterday containing a sample database, LDAP information, and a list of the companies that they claimed were stolen from Oracle Clouds’ SSO platform.
As further proof that they had access to Oracle Cloud servers, the threat actor shared this URL with BleepingComputer, showing an Internet Archive URL that indicates they uploaded a .txt file containing their ProtonMail email address to the login.us2.oraclecloud.com server.
BleepingComputer contacted Oracle again to explain how the threat actor uploaded a text file containing their email address without access to Oracle Cloud servers.

Companies can pay a specific amount to remove their employees’ information from the list before it’s sold.”
They’ve also offered to share some of the data with anyone who can help decrypt the SSO passwords or crack the LDAP passwords.
The threat actor told BleepingComputer they gained access to Oracle Cloud servers around 40 days ago and claimed to email the company after exfiltrating data from the US2 and EM2 cloud regions.
In the email exchange, rose87168 said they asked Oracle to pay 100,000 XMR for information on how they breached the servers, but the company allegedly refused to pay after asking for “all information needed for fix and patch
