Broadcom Breach Incident Score: Analysis & Impact (BRO0893008112125)

In this Rankiteo incident briefing, we review the Broadcom breach identified under incident ID BRO0893008112125.

The analysis begins with a detailed overview of Broadcom's information like the linkedin page: https://www.linkedin.com/company/vmware, the number of followers: 589166, the industry type: Semiconductor Manufacturing and the number of employees: 53946 employees

After the initial compromise, the video explains how Rankiteo's incident engine converts technical details into a normalized incident score. The incident score before the incident was 603 and after the incident was 603 with a difference of 0 which is could be a good indicator of the severity and impact of the incident.

In the next step of the video, we will analyze in more details the incident and the impact it had on Broadcom and their customers.

Broadcom Inc. recently reported "Cl0p Ransomware Gang Claims Breach of Broadcom via Zero-Day in Oracle E-Business Suite", a noteworthy cybersecurity incident.

The Cl0p ransomware gang has publicly claimed responsibility for breaching Broadcom, a leading semiconductor and infrastructure software company.

The disruption is felt across the environment, affecting Oracle E-Business Suite, supply chain operations and financial systems.

Formal response steps have not been shared publicly yet.

The case underscores how unverified (claimed by Cl0p, no official statement from Broadcom; independent verification pending), teams are taking away lessons such as Zero-day vulnerabilities in enterprise software (e.g., Oracle E-Business Suite) pose severe risks due to lack of patches at exploitation time, High-value targets (e.g., semiconductor manufacturers) are prioritized by ransomware groups like Cl0p for maximum impact and Proactive measures (e.g., network segmentation, EDR, threat intelligence monitoring) are critical for mitigating zero-day risks, and recommending next steps like Immediately review security logs for unauthorized access attempts in Oracle E-Business Suite environments, Apply security patches for Oracle E-Business Suite as soon as they are released and Implement network segmentation to limit lateral movement in case of breach.

Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.

The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.

Rankiteo's analysis has identified several MITRE ATT&CK tactics and techniques associated with this incident, each with varying levels of confidence based on available evidence. Under the Initial Access tactic, the analysis identified Exploit Public-Facing Application (T1190) with high confidence (95%), supported by evidence indicating unpatched zero-day vulnerability in Oracle E-Business Suite (arbitrary code execution) and Exploitation for Privilege Escalation (T1068) with moderate to high confidence (85%), supported by evidence indicating vulnerability allows arbitrary code execution, persistent access. Under the Execution tactic, the analysis identified Command and Scripting Interpreter (T1059) with moderate to high confidence (80%), supported by evidence indicating arbitrary code execution via Oracle E-Business Suite zero-day. Under the Persistence tactic, the analysis identified Server Software Component: Web Shell (T1505.003) with moderate to high confidence (75%), supported by evidence indicating backdoors established (likely) for persistence. Under the Privilege Escalation tactic, the analysis identified Exploitation for Privilege Escalation (T1068) with moderate to high confidence (85%), supported by evidence indicating arbitrary code execution enabling elevated privileges. Under the Defense Evasion tactic, the analysis identified Impair Defenses: Disable or Modify Tools (T1562.001) with moderate to high confidence (70%), supported by evidence indicating persistent access suggests disabling security tools and Indicator Removal: File Deletion (T1070.004) with moderate confidence (65%), supported by evidence indicating cl0ps typical post-exploitation cleanup (implied). Under the Credential Access tactic, the analysis identified OS Credential Dumping (T1003) with moderate to high confidence (80%), supported by evidence indicating credential theft listed in attack vectors and Credentials from Password Stores (T1555) with moderate to high confidence (75%), supported by evidence indicating eRP systems often store credentials for supply chain/financial systems. Under the Discovery tactic, the analysis identified File and Directory Discovery (T1083) with moderate to high confidence (70%), supported by evidence indicating lateral movement implies reconnaissance for high-value data and Remote System Discovery (T1018) with moderate to high confidence (70%), supported by evidence indicating lateral movement across corporate networks. Under the Lateral Movement tactic, the analysis identified Remote Services: Remote Desktop Protocol (T1021.001) with moderate to high confidence (75%), supported by evidence indicating lateral movement across corporate networks and Remote Services: SMB/Windows Admin Shares (T1021.002) with moderate to high confidence (70%), supported by evidence indicating common Cl0p tactic for moving between ERP-connected systems. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating exfiltrated sensitive corporate data (IP, manufacturing secrets, customer info) and Data from Network Shared Drive (T1039) with moderate to high confidence (85%), supported by evidence indicating eRP systems like Oracle E-Business Suite often link to shared drives. Under the Exfiltration tactic, the analysis identified Exfiltration Over Alternative Protocol: Exfiltration Over Unencrypted/Obfuscated Non-C2 Protocol (T1048.003) with moderate to high confidence (80%), supported by evidence indicating data exfiltration claimed by Cl0p (typical tactic before ransomware) and Exfiltration Over C2 Channel (T1041) with moderate to high confidence (75%), supported by evidence indicating cl0ps standard exfiltration via C2 infrastructure. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (95%), supported by evidence indicating likely data encryption (standard Cl0p tactic post-exfiltration) and Data Destruction (T1485) with moderate confidence (60%), supported by evidence indicating potential secondary impact of ransomware deployment. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
