The **Cl0p ransomware gang** breached **Broadcom**, a $300+ billion semiconductor and infrastructure software leader, by exploiting an **unpatched zero-day vulnerability in Oracle E-Business Suite**. This ERP platform manages critical operations, including **supply chain, financial systems, and customer data**, making it a high-value target. The attackers likely **exfiltrated sensitive corporate data** (potentially including **intellectual property, manufacturing secrets, and customer information**) before deploying ransomware, following Cl0p’s typical double-extortion tactic. The breach risks **operational disruptions in global manufacturing**, **regulatory penalties for data exposure**, and **reputational damage** due to the involvement of a notorious ransomware group. The use of a **zero-day exploit** amplifies the threat, as other organizations using Oracle E-Business Suite may face similar attacks until a patch is released. Broadcom has not confirmed the incident, but the alleged compromise aligns with Cl0p’s pattern of targeting **high-value enterprises** via unpatched vulnerabilities in widely used software.
