Transparent Forwarders: An Unnoticed Component of the Open DNS Infrastructure
Marcin Nawrocki, Maynard Koch, Thomas C. Schmidt +1
In this paper, we revisit the open DNS (ODNS) infrastructure and, for the first time, systematically measure and analyze transparent forwarders, DNS components that transparently r…
Spoki: Unveiling a New Wave of Scanners through a Reactive Network Telescope
Raphael Hiesgen, Marcin Nawrocki, Alistair King +3
Large-scale Internet scans are a common method to identify victims of a specific attack. Stateless scanning like in ZMap has been established as an efficient approach to probing at…
The Far Side of DNS Amplification: Tracing the DDoS Attack Ecosystem from the Internet Core
Marcin Nawrocki, Mattijs Jonker, Thomas C. Schmidt +1
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 passive at…
QUICsand: Quantifying QUIC Reconnaissance Scans and DoS Flooding Events
Marcin Nawrocki, Raphael Hiesgen, Thomas C. Schmidt +1
In this paper, we present first measurements of Internet background radiation originating from the emerging transport protocol QUIC. Our analysis is based on the UCSD network teles…
Uncovering Vulnerable Industrial Control Systems from the Internet Core
Marcin Nawrocki, Thomas C. Schmidt, Matthias Wählisch
Industrial control systems (ICS) are managed remotely with the help of dedicated protocols that were originally designed to work in walled gardens. Many of these protocols have bee…
