Quad9 partners with a large number of threat intelligence sources who provide up-to-the-minute data about domains that pose a threat because of malware, phishing, botnets, or other malicious activities. Quad9 uses vetted open-source threat data as well as donated information from commercial sources.

Quad9 provides both security and privacy features for DNS. Quad9 uses threat intelligence data at the recursive resolver to prevent a client from accessing a malicious site. This recursive resolver does not store or distribute the DNS data passing through.

The court also seemed to accept Sony's argument that Quad9 already blocks problematic websites (e.g. those that contain malware – viruses, spyware etc.), despite that being a very different consideration. Quad9's General Manager, John Todd, said: 'Quad9 derives its threat intelligence from qualified experts on malware and phishing, not from the claims of parties without relevant expertise. We would be unable to maintain our 98% success rate in blocking cyber-threats if we accepted input based on self-interested claims, rather than on forensics and expert analysis.' we could imagine that many more Rights Holders may rush to make use of this for similar websites. Naturally, Quad9 intends to appeal and so the battle is not yet over.

Last week, the new DNS resolver Quad9 has been announced. It is a public DNS resolver with the additional benefit that it is accessible in a secure way. There are other public DNS resolvers, but the link to them is not secure. This allows hijackings as well as third-party monitoring. The new Quad9 service on the other hand is operated by the not-for-profit Packet Clearing House (PCH), which manages large parts of the DNS infrastructure, and it allows access to the DNS over TLS. This makes it very difficult for third parties to listen in. And it makes it possible to authenticate the resolver.

↑  Huston، Geoff (11 فبراير 2022). "Opinion: DNS4EU". APNIC. مؤرشف من الأصل في 2023-12-11. Sony Music Germany bought a suit against the DNS open resolver provider Quad9 in a German court. The court ruled that Quad9 must block the resolution of a domain name of a website in Ukraine that itself does not hold copyright-infringing material, but instead contains pointers to another website that is reported to hold alleged copyright infringements. Quad9's interpretation of this ruling is that queries received from IP addresses that can be geolocated to Germany must generate a SERVFAIL response from Quad9's recursive resolvers.
↑  Van der Sar، Ernesto (21 يونيو 2021). "Sony Wins Pirate Site Blocking Order Against DNS-Resolver Quad9". TorrentFreak. مؤرشف من الأصل في 2024-09-10. اطلع عليه بتاريخ 2021-06-21. Sony Music has obtained an injunction that requires the freely available DNS-resolver Quad9 to block a popular pirate site. The order, issued by the District Court in Hamburg, Germany, is the first of its kind. The Quad9 foundation has already announced that it will protest the judgment, which could have far-reaching consequences. The Hamburg court found that the DNS service is not eligible for the liability protections that other third-party intermediaries such as ISPs and domain registrars typically enjoy. And if Quad9 fails to comply with the injunction, it will have to pay a fine of 250,000 euros per 'infringing' DNS query plus potentially two years in prison.

↑  Grüner، Sebastian (21 يونيو 2021). "Sony will DNS-Sperre bei Quad9 durchsetzen". Golem. مؤرشف من الأصل في 2023-02-22. اطلع عليه بتاريخ 2021-06-21. The DNS provider Quad9, which is now officially located in Switzerland, is held liable as a "Stoerer" (interferer) in this case, because the DNS resolution of the service enables copyright infringement. The "Stoererhaftung" (Breach of Duty of Care), its effects on copyright law, and any associated warnings against private individuals or even companies have been a point of contention in the law-making process of politics and the judiciary for decades. What is surprising about the current case is that Internet providers and registrars are actually exempt from "Stoererhaftung" (Breach of Duty of Care) under the so-called provider privilege. However, the Hamburg Regional Court apparently sees things differently.

Sony Music has won an injunction requiring a DNS resolver to block a popular piracy site. The ruling is the first of its kind and may signal a new direction in tackling music piracy. The order was issued by the District Court in Hamburg, Germany. The Hamburg Court ruling finds that DNS resolvers like Quad9 are not eligible for liability protections like ISPs and domain registrars. If Quad9 fails to block the infringing site, it faces a fine of up to $298,356.00 (€250,000) per infringing DNS query it processes and a potential prison stint of up to two years.
↑  "Quad9 and Sony Music: German Injunction Status". Quad9. 24 يونيو 2021. مؤرشف من الأصل في 2021-06-24. اطلع عليه بتاريخ 2021-06-25. Quad9 was notified last Friday that Sony Music had obtained an injunction against Quad9 in the lower court of Hamburg, Germany, seeking to block DNS resolution of domains used to host music content files on the grounds that such resolution contributes to infringement upon Sony's copyrights. Quad9 has no relationship with any of the parties to the alleged infringement. Our systems resolve domain names, conveying public information on the public Internet, as any other recursive resolver would do, and there is no allegation that the domain names themselves, or any information that Quad9 has handled, infringe upon Sony's copyrights. We have retained counsel, and we are in the process of filing an objection to the injunction.
