Trustwave’s Spider Labs, meanwhile, said the sample of LDAP credentials provided by rose87168 “reveals a substantial amount of sensitive IAM data associated with a user within an Oracle Cloud multi-tenant environment. The data includes personally identifiable information (PII) and administrative role assignments, indicating potential high-value access within the enterprise system.”

Oracle initially denied any such breach had occurred against its cloud infrastructure, telling publications: “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.”

On Friday, when I asked Oracle for comment, a spokesperson asked if they could provide a statement that couldn’t be attributed to Oracle in any way. After I declined, the spokesperson said Oracle would have no comment.

For the moment, there’s a stand-off between Oracle on the one hand, and researchers and journalists on the other, over whether two serious breaches have exposed sensitive information belonging to its customers. Reporting that Oracle is notifying customers of data compromises in unofficial letterhead sent by outside attorneys is also concerning. This post will be updated if new information becomes available.
