DNS amplification attack is a significant and persistent threat to the Internet. Authoritative
name servers (ANSes) of popular domains, especially the DNSSEC-enabled ones, give …

We present DNS Unchained, a new application-layer DoS attack against core DNS
infrastructure that for the first time uses amplification. To achieve an attack amplification of …

Domain name system (DNS) resolves the IP addresses of domain names and is critical for IP
networking. Recent denial-of-service (DoS) attacks on Internet targeted the DNS system (eg …

Authoritative DNS infrastructures are at the core of the Internet ecosystem. But how resilient
are typical authoritative DNS name servers against application-layer Denial-of-Service …

In this paper, we shed new light on the DNS amplification ecosystem, by studying
complementary data sources, bolstered by orthogonal methodologies. First, we introduce a …

Abstract Domain Name System (DNS) amplification attack is a sophisticated Distributed
Denial of Service (DDoS) attack by sending a huge volume of DNS name lookup requests to …

Abstract The Internet Domain Naming System (DNS) is one of the pillars for the Internet and
has been the subject of various Distributed Denial-of-Service (DDoS) attacks over the years …

In this paper, we propose an approach for detecting internal and external network scanning
attacks on enterprise networks. In our approach, an inline scan detection system (SDS) …

In the past decades, DNS has gradually risen into one of the most important systems on the
Internet. Malicious actors have long misused it in reflection and amplification DDoS attacks …

Attackers have used DNS amplification in over 34% of high-volume DDoS attacks, with
some floods exceeding 300 Gbps. The best current practices do not help victims during an …
