This forced shipping firms to use unencrypted connections that, according to Toker, could leave their data vulnerable to interception.While no data breaches resulting from the use of these connections have been made known, and there are no known instances in which a shipping firm’s data was intercepted and used to its detriment because of the certificate expiration, Toker said the site’s inaccessibility resulted in a shift t...
