Logitech said it had recently experienced a cybersecurity incident and believed an unauthorized third party had used a zero-day vulnerability (a flaw exploited before a fix exists) in a third-party software platform to copy data from its internal IT system. The data likely included limited information about employees and consumers and data relating to customers and suppliers, and Logitech did not believe any sensitive personal information, such as national ID numbers or credit card information, was in the affected system. The company said the incident had not affected its products, business operations or manufacturing, that it had patched the flaw, and that as of the filing it believed the incident would not have a material adverse effect on its financial condition or results of operations. Logitech disclosed the incident in an 8-K, a US company's report of a material event, filed Nov 14, 2025 on SEC EDGAR, and said its investigation was ongoing.1^,2^,3^,4^,5^,6^,7
