In the Encrochat case, French police deployed malware to Encrochat phones and obtained the content of users&#8217; messages.<\/p>\n<p><\/span><span><\/p>\n<div class=\"adph adph--border\">\n<p>Advertisement<\/p>\n<\/div>\n<p><\/span><span class=\"abc__textblock size--article\" data-component=\"TextBlock\" readability=\"33\"><\/p>\n<p>&#8220;EncroChat encrypt their messages with the Signal Protocol. This is a commonly used encryption protocol that is freely available.
