Oracle Cloud Confirms Second Hack in a Month, Client Log-in Data Stolen

A hacker infiltrated an older Oracle system and stole login credentials from client accounts, some of which date back as recently as 2024.

 

Oracle Corporation has warned customers of a second cybersecurity incident in the last month, according to Bloomberg News. A hacker infiltrated an older Oracle system and stole login credentials from client accounts, some of which date back as recently as 2024. 

The tech company reportedly informed clients that an attacker had gained access to a legacy environment—a system that had not been in active operation for roughly eight years. Although Oracle told clients that the environment had been dormant, the data retrieved included valid login credentials, which might pose a security concern, especially if users had not updated or deleted their accounts. 

This follows a prior hack last month, in which an anonymous individual attempted to sell stolen Oracle data online, prompting internal investigations. That incident, too, involved data stolen from Oracle's cloud servers in Austin, Texas. 

The FBI and cybersecurity firm CrowdStrike Holdings are presently looking into the most recent incident, Oracle informed some of its clients. According to individuals who spoke to Bloomberg, the attacker is thought to have demanded an extortion payment. Interestingly, Oracle has declared that there is no connection between the two incidents. 

According to the firm, this breach occurred due to an outdated, dormant system, whereas the previous one affected specific clients in the healthcare sector. Oracle has not yet released a statement to the public, but according to Reuters, the company told customers directly and stressed that the impact is minimal because of how old the system in question is. 

Last month, Oracle also notified clients last month of a compromise at the software-as-a-service (SaaS) company Oracle Health (formerly Cerner), which affected many healthcare organisations and hospitals in the United States.

Even though the company has not publicly reported the event, threat analysts confirmed that patient data was stolen during the attack, as evidenced by private contacts between Oracle Health and impacted clients, as well as talks with people involved. Oracle Health reported that the breach of legacy Cerner data transfer servers occurred on February 20, 2025, and that the perpetrators accessed the systems using compromised client credentials after January 22, 2025.
