What if DNS was the Achilles heel of the security of your personal data? In order for an address to be written instead of an IP address to reach a site, Domain Name Servers or domain name servers have been around since the beginning of the web. Today they form the backbone of the network, so an incredible amount of data passes through these nodes every second. including personal data.
Chrome: When DNS betrays your history
The problem is, your data is forwarded to these servers on port 53 openly. And because it is not encrypted, it becomes possible for the owner of the DNS server to see your activity – in other words, a detailed history of the sites you visit. visit. However, your ISP’s DNS, be it Google (8.8.8.8, 8.8.4.4), Cloudflare (1.1.1.1, 1.0.0.1), OpenDNS (208.67.220.220, 208.67.222.222) or even FDN (80.67.222.222) . 169.12, 80.67.169.40), all have unencrypted access to this data.
Of course there is a solution: DNS over HTTPSconsists of completely encrypting the data passing through these servers. But not all browsers allow them to be enabled by default. That’s why Firefox has been offering simplified activation for a few weeks now, but Google Chrome still has no subscribers – but it’s by far the most used browser in France and around the world. Fortunately, it remains possible to force the use of these encrypted DNSs with a trick.
