Oracle Corporation recently confirmed a data breach involving its older Generation 1 (Gen 1) servers. This incident marks the second cybersecurity event disclosed by the tech giant in recent weeks. In this blog post, we delve into the details of the breach, its potential implications for enterprise security, and best practices to mitigate such risks.

Overview of the Oracle Data Breach

On March 20, 2025, a threat actor, using the pseudonym “rose87168,” claimed responsibility for the attack on Oracle’s legacy Gen 1 servers. According to the initial report posted on Breachforums, the attacker managed to access approximately 6 million data records. Although the compromised records primarily include usernames, email addresses, hashed passwords, and certain authentication credentials, the breach has raised broader concerns about the security measures in place for Oracle’s older systems.

Oracle has verified that while the exposed data does not include complete Personally Identifiable Information (PII), it does involve sensitive authentication details such as Single Sign-On (SSO) and Lightweight Directory Access Protocol (LDAP) information. In addition, the attacker exfiltrated Java Key Store (JKS) files and Enterprise Manager JPS keys, which are crucial for maintaining secure communications and system integrity.

Background on Legacy Systems and Security Challenges

Understanding Gen 1 Servers

Oracle’s Gen 1 servers represent older infrastructure that, although reliable in their time, are now facing challenges in keeping up with modern cybersecurity threats. These legacy systems were designed in an era when cyber threats were far less sophisticated. As organizations have rapidly adopted cloud technologies, these older servers often become vulnerable entry points if not updated or fully integrated into newer security frameworks.

The Importance of Regular Updates and Migration

Legacy systems, such as Oracle’s Gen 1 servers, may not receive the same level of regular security patches and updates as modern systems. This gap leaves them susceptible to exploits that take advantage of outdated protocols and software vulnerabilities. In the case of Oracle, the breach was facilitated by a Java exploit dating back to 2020. This vulnerability enabled the attacker to deploy a web shell and malware, ultimately targeting Oracle’s Identity Manager (IDM) database.

How the Breach Unfolded

Initial Access and Exploitation

Security analysts have determined that the attacker, “rose87168,” may have gained access to Oracle’s legacy systems as early as January 2025. The breach remained undetected until late February when Oracle initiated an internal investigation. The prolonged undetected period provided the attacker ample time to move laterally within the network and exfiltrate sensitive data.

The exploitation process involved a known vulnerability in Java, a programming language and platform widely used in enterprise applications. By leveraging this vulnerability, the attacker could bypass certain security measures and install malicious software. The use of a web shell—a remote access tool that gives attackers control over a compromised system—was critical in facilitating ongoing access to Oracle’s legacy systems.

Types of Data Compromised

The data stolen in the breach encompasses multiple categories:

User Credentials: Usernames and email addresses were among the compromised records.
Authentication Details: Hashed passwords, along with SSO and LDAP credentials, were exposed.
Security Keys and Certificates: The attacker exfiltrated critical files, such as Java Key Store (JKS) files and Enterprise Manager JPS keys, which are instrumental in managing encryption and secure communication within Oracle’s network.

Although Oracle confirmed that the compromised data was approximately 16 months old and did not contain complete PII, the breach still represents a significant risk, especially if similar tactics are used in future attacks targeting more current systems.

Analysis of the Threat Actor

Profile of “rose87168”

The individual behind this breach, operating under the handle “rose87168,” appears to be a relatively new entrant in the cybercrime landscape. The account used by the threat actor was reportedly created in March 2025, suggesting that the actor might be either an emerging criminal or a new team member within a larger criminal organization. The primary motive appears to be financial, as indicated by the subsequent ransom demand of $20 million directed at Oracle.

Criminal Ambitions and Data Exchange Tactics

Beyond financial extortion, “rose87168” has hinted at broader criminal ambitions.
