Logitech has confirmed a cybersecurity incident after the Clop ransomware gang claimed responsibility for stealing more than 1 TB of company data. The breach occurred through a zero-day vulnerability in a third-party software platform, not through Logitech’s own products or core systems. The vulnerability has since been patched.

The stolen information likely includes limited data about employees, consumers, customers, and suppliers, although Logitech says it does not believe highly sensitive data—such as national ID numbers or credit card details—was stored in the affected system. However, this is based on current belief rather than verified certainty.

Logitech reported the incident in a Form 8-K filing with the SEC and has begun required notifications to government authorities. The company states that the breach is not expected to materially impact financial performance and notes that it has cybersecurity insurance to cover investigation and response costs.

Cybersecurity experts emphasize that attacks like this highlight the limitations of relying solely on software-based defenses, since zero-days can be exploited before patches exist. They urge companies to adopt broader, hardware-rooted security strategies and treat incidents like this as a call for immediate, proactive action instead of another routine warning.
