Logitech was targeted by the **Clop ransomware group**, exploiting a zero-day vulnerability in **Oracle E-Business Suite**. The attack resulted in a **serious data breach**, exposing **1.8 TB of stolen data**, including **limited employee, user, customer, and supplier details**. While Logitech confirmed that **sensitive information like ID cards, bank details, or highly confidential data was not compromised** (as it was not stored on the affected systems), the breach still involved **significant internal and customer data leaks**. The company engaged third-party cybersecurity experts and applied an emergency patch, but the data had already been exfiltrated. Clop threatened to disclose the stolen data unless a ransom was paid, and Logitech was added to the group’s **data dump site**. The incident did not disrupt production, business processes, or product operations, but the **scale of exposed data**—including employee and customer records—poses reputational and operational risks.
