On March 21, 2025, a user named rose87168 took to BreachForums to announce the sale of sensitive data allegedly exfiltrated from Oracle Cloud. This included SSO & LDAP credentials, OAuth2 keys, and customer tenant information, affecting over 140,000 individuals and businesses.
In response to this alarming revelation, CloudSEK's XVigil platform promptly identified a significant threat. "Our deep-dive investigation reveals a compromised production SSO endpoint, affecting over 140,000 tenants and exposing sensitive SSO and LDAP data," said a spokesperson from CloudSEK.

Despite the seriousness of the situation, Oracle issued a swift denial, asserting, "There has been no breach of Oracle Cloud," on the same day the threat was made public. However, CloudSEK, dedicated to transparency and action, has made it their mission to verify claims and equip organizations with the necessary tools to assess security risks.
"There has been no breach of Oracle Cloud,"
"At CloudSEK, we prioritize transparency and preparedness," said the company. The follow-up report published by CloudSEK offers insight into this troubling incident, detailing verified evidence of the breach and actionable steps for enterprises to strengthen their defenses.

The investigation revealed that the threat actor not only provided a sample list of customer details from Oracle but also uploaded evidence supporting their claims. This included a file created on "login.us2.oraclecloud.com" that contained the attacker's email, further substantiating the seriousness of the allegations.
Race Results
Efforts by CloudSEK didn’t stop at exposure verification. They issued a TLP Green report to alert the community about potential supply chain attacks stemming from this data breach and sent a more urgent TLP RED report to Oracle the same day. "We believe there was a lack of judgment at the end of Oracle, and we intend to publish more details that would help the community and Oracle to investigate the incident better," said a CloudSEK representative.
