Schlüsselstellen des Internets in Gefahr

[Quelle: Basler Zeitung, (roy/SDA), Erstellt: 23.02.2019, 06:37 Uhr]

Die Internet-Adressverwaltung warnt vor einem Angriff auf die Netz-Infrastruktur. Die Spuren führen in den Iran.

Es bestehe ein «anhaltendes und erhebliches Risiko» für wichtige Bestandteile der mit Webseiten zusammenhängenden Infrastruktur. Dies teilte die Internet Corporation for Assigned Names and Numbers (ICANN) nach einer Dringlichkeitssitzung am Freitag (Ortszeit) mit.

Konkret hätten unbekannte Angreifer die Adressen von Webseiten verändert, unter anderem, um so an persönliche Daten von Nutzern zu gelangen, erklärte die Internet-Adressverwaltung ICANN weiter. Die Attacken könnten zwar bis ins Jahr 2017 zurückreichen, hätten bei Spezialisten für Internet-Sicherheit in den vergangenen Wochen aber zu erheblicher Besorgnis geführt. Daraufhin wurde die Dringlichkeitssitzung einberufen.

Spur führt in den Iran
Die US-Behörden hatten unlängst vor Angriffen auf das System der Adressen von Webseiten gewarnt. «Dies ist in etwa vergleichbar mit jemanden, der das Postbüro über ihre Adresse belügt, Ihre Briefe überprüft und sie dann selbst in ihren Briefkasten wirft», erklärte das US-Ministerium für Innere Sicherheit. «Viele schädliche Dinge könnte Ihnen angetan werden (oder den Absendern), abhängig vom Inhalt der Post.»

Nach Angaben von ICANN-Experten zielten die Angriffe sowohl auf Regierungen als auch auf Geheimdienste, die Polizei oder Unternehmen. Betroffen seien sowohl Europa als auch der Nahe Osten. Nach Angaben des Spezialist für Cyber-Spionage Ben Read führen die Spuren des Angriffs in den Iran.

Wenn Sie sich nicht sicher sind, auf die von Ihnen gewünschte Webseite ‘gelotst zu werden, können Sie mittels Trace Route überprüfen, welchen Weg Ihr Webseitenaufruf im Netz geht:

ICANN Calls for Full DNSSEC Deployment, Promotes Community Collaboration to Protect the Internet
LOS ANGELES – 21 February 2019 – The Internet Corporation for Assigned Names and Numbers (ICANN) believes that there is an ongoing and significant risk to key parts of the Domain Name System (DNS) infrastructure.

In the context of increasing reports of malicious activity targeting the DNS infrastructure, ICANN is calling for full deployment of the Domain Name System Security Extensions (DNSSEC) across all unsecured domain names. The organization also reaffirms its commitment to engage in collaborative efforts to ensure the security, stability and resiliency of the Internet’s global identifier systems.

As one of many entities engaged in the decentralized management of the Internet, ICANN is specifically responsible for coordinating the top-most level of the DNS to ensure its stable and secure operation and universal resolvability.

On 15 February 2019, in response to reports of attacks against key parts of the DNS infrastructure, ICANN offered a checklist of recommended security precautions for members of the domain name industry, registries, registrars, resellers, and related others, to proactively take to protect their systems, their customers’ systems and information reachable via the DNS.

Public reports indicate that there is a pattern of multifaceted attacks utilizing different methodologies. Some of the attacks target the DNS, in which unauthorized changes to the delegation structure of domain names are made, replacing the addresses of intended servers with addresses of machines controlled by the attackers. This particular type of attack, which targets the DNS, only works when DNSSEC is not in use. DNSSEC is a technology developed to protect against such changes by digitally ‘signing’ data to assure its validity. Although DNSSEC cannot solve all forms of attack against the DNS, when it is used, unauthorized modification to DNS information can be detected, and users are blocked from being misdirected.

ICANN has long recognized the importance of DNSSEC and is calling for full deployment of the technology across all domains. Although this will not solve the security problems of the Internet, it aims to assure that Internet users reach their desired online destination by helping to prevent so-called “man in the middle” attacks where a user is unknowingly re-directed to a potentially malicious site. DNSSEC complements other technologies, such as Transport Layer Security (most typically used in HTTPS) that protect the end user/domain communication.

As the coordinator of the top-most level of the DNS, ICANN is in the position to help mitigate and detect DNS-related risks, and to facilitate key discussions together with its partners. The organization believes that all members of the domain name system ecosystem must work together to produce better tools and policies to secure the DNS and other critical operations of the Internet. To facilitate these efforts, ICANN is planning an event for the Internet community to address DNS protection: The first is an open session during the upcoming ICANN64 public meeting on 9-14 March 2019, in Kobe, Japan.

Alert Regarding Published Reports of Attacks on the Domain Name System

LOS ANGELES – 15 February 2019 – The Internet Corporation for Assigned Names and Numbers (ICANN) today announced that it is aware of several recent public reports regarding malicious activity targeting the Domain Name System (DNS). We have no indication that any ICANN organization systems have been compromised, and we are working with relevant community members to investigate reports of attacks against top-level domains (TLDs).
