Even though Kyos Exchange Servers have not been affected, 50% of our customers with on-premise Exchange Servers have been impacted, despite the application of the patch that we performed the same day.","og_url":"https:\/\/www.kyos.ch\/en\/sec-en\/exchange-zero-day-exploit\/","og_site_name":"KYOS","article_published_time":"2021-03-09T15:40:00+00:00","article_modified_time":"2023-05-05T12:07:55+00:00","og_image":[{"width":640,"height":427,"url":"https:\/\/www.kyos.ch\/wp-content\/uploads\/2021\/06\/Kyos_Post_Exchange_Article.jpg","type":"image\/jpeg"}],"author":"Etienne Maghakian","twitter_card":"summary_large_image","twitter_misc":{"Written by":"Etienne Maghakian","Est. reading time":"4 minutes"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"Article","@id":"https:\/\/www.kyos.ch\/en\/sec-en\/exchange-zero-day-exploit\/#article","isPartOf":{"@id":"https:\/\/www.kyos.ch\/en\/sec-en\/exchange-zero-day-exploit\/"},"author":{"name":"Etienne Maghakian","@id":"https:\/\/www.kyos.ch\/#\/schema\/person\/10c03a166f24b0dfb247a0c084600db4"},"headline":"Exchange zero-day Exploit","datePublished":"2021-03-09T15:40:00+00:00","dateModified":"2023-05-05T12:07:55+00:00","mainEntityOfPage":{"@id":"https:\/\/www.kyos.ch\/en\/sec-en\/exchange-zero-day-exploit\/"},"wordCount":706,"publisher":{"@id":"https:\/\/www.kyos.ch\/#organization"},"image":{"@id":"https:\/\/www.kyos.ch\/en\/sec-en\/exchange-zero-day-exploit\/#primaryimage"},"thumbnailUrl":"https:\/\/www.kyos.ch\/wp-content\/uploads\/2021\/06\/Kyos_Post_Exchange_Article.jpg","articleSection":["Security"],"inLanguage":"en-US"},{"@type":"WebPage","@id":"https:\/\/www.kyos.ch\/en\/sec-en\/exchange-zero-day-exploit\/","url":"https:\/\/www.kyos.ch\/en\/sec-en\/exchange-zero-day-exploit\/","name":"Exchange zero-day Exploit -
