DNSSEC Usage in Switzerland is on the rise after widespread attacks on the Domain Name System

Attacks on the DNS System

Cyber attacks on the DNS system are not new. Cache poisoning, Domain Hijacking and BGP injections of routes to public DNS resolvers happen regularly, but they usually don’t get much attention as they target the Internet’s core infrastructure and are not directly visible to end users in most cases. This time it was different. The recent widespread DNS hijacking attacks on several Mid East, North African and European and North American governments and infrastructure providers, published by Ciscos Talos showed that DNS attacks are a real threat to cyber security. Netnod, one of the affected infrastructure providers issued a statement, that called, amongst other domain security mechanisms, for the implementation of the DNS Security Extensions (DNSSEC).

The analysis of these attacks also convinced the Internet Corporation for Assigned Names and Numbers (ICANN) that there is an ongoing and significant risk to key parts of the System (DNS) infrastructure. ICANN issued a call for “Full DNSSEC Deployment to Protect the Internet” across all unsecured domain names.

The question is if  these attacks and the awareness that DNSSEC is an absolute essential base layer protection for domain names had some effects on the Implementation of DNSSEC Switzerland?

More DNSSEC signed domain names

As a ccTLD operator SWITCH publishes the number of DNSSEC signed .ch and .li domain names every month. While the number of signed domain names is still very low at around 3-4% we see a rise in the numbers of signed domain names for two years now.

DNSSEC signed .ch domain names 1.4.2019

Breaking security controls using subdomain hijacking

Users obtain a domain name to establish a unique identity on the Internet. Domain names are not only used to serve names and addresses of computers and services but also to store security controls, such as SPF or CAA records. Many of the Internet protocols were designed at a time where built-in security was not a requirement. The IETF continues to standardize protocol extensions to address today’s security needs.

For some protocols security is added with controls stored in your domain names zone file. In order to have the desired effect, the pre-condition is of course that your domain name is secure. In other words, the security of your application that makes use of controls in DNS is only as secure as the security of your domain name.

Hijacking a domain name because of weak credentials at the registrar may get the job done but this is far from stealthy and will likely not last long. In many cases it is sufficient to hijack an abandoned subdomain. Taking over abandoned subdomains may be unnoticed by the owner for a very long period of time making it also very useful for targeted attacks.

Picture 1: update.ft.com has been hijacked and the content from the ft.com front page is mirrored with a fake article about subdomain hijacking. Note: the website is not online anymore, Financial Times has been notified to remove the abandoned record from their zone file. A Certificate Transparency (CT) log proves that a TLS certificate has been issued for this demo site.
