Scanning the IPv6 Internet Using Subnet-Router Anycast Probing
Maynard Koch, Raphael Hiesgen, Marcin Nawrocki +2
Identifying active IPv6 addresses is challenging. Various methods emerged to master the measurement challenge in this huge address space, including hitlists, new probing techniques…
A Detailed Measurement View on IPv6 Scanners and Their Adaption to BGP Signals
Isabell Egloff, Raphael Hiesgen, Maynard Koch +2
Scanners are daily visitors of public IPv4 hosts. Scanning IPv6 nodes successfully is still a challenge, which an increasing crowd of actors tries to master. In this paper, we anal…
A Call to Reconsider Certification Authority Authorization (CAA)
Pouyan Fotouhi Tehrani, Raphael Hiesgen, Thomas C. Schmidt +1
Certification Authority Authentication (CAA) is a safeguard against illegitimate certificate issuance. We show how shortcomings in CAA concepts and operational aspects undermine it…
ReACKed QUICer: Measuring the Performance of Instant Acknowledgments in QUIC Handshakes
Jonas Mücke, Marcin Nawrocki, Raphael Hiesgen +2
In this paper, we present a detailed performance analysis of QUIC instant ACK, a standard-compliant approach to reduce waiting times during the QUIC connection setup in common CDN…
The Age of DDoScovery: An Empirical Comparison of Industry and Academic DDoS Assessments
Raphael Hiesgen, Marcin Nawrocki, Marinho Barcellos +14
Motivated by the impressive but diffuse scope of DDoS research and reporting, we undertake a multistakeholder (joint industry-academic) analysis to seek convergence across the best…
Do CAA, CT, and DANE Interlink in Certificate Deployments? A Web PKI Measurement Study
Pouyan Fotouhi Tehrani, Raphael Hiesgen, Teresa Lübeck +2
Integrity and trust on the web build on X.509 certificates. Misuse or misissuance of these certificates threaten the Web PKI security model, which led to the development of several…
Pool Inference Attacks on Local Differential Privacy: Quantifying the Privacy Guarantees of Apple's Count Mean Sketch in Practice
Andrea Gadotti, Florimond Houssiau, Meenatchi Sundaram Muthu Selva Annamalai +1
Behavioral data generated by users' devices, ranging from emoji use to pages visited, are collected at scale to improve apps and services. These data, however, contain fine-grained…
SoK: A Data-driven View on Methods to Detect Reflective Amplification DDoS Attacks Using Honeypots
Marcin Nawrocki, John Kristoff, Raphael Hiesgen +3
In this paper, we revisit the use of honeypots for detecting reflective amplification attacks. These measurement tools require careful design of both data collection and data analy…
On the Interplay between TLS Certificates and QUIC Performance
Marcin Nawrocki, Pouyan Fotouhi Tehrani, Raphael Hiesgen +3
In this paper, we revisit the performance of the QUIC connection setup and relate the design choices for fast and secure connections to common Web deployments. We analyze over 1M W…
Waiting for QUIC: Passive Measurements to Understand QUIC Deployments
Jonas Mücke, Marcin Nawrocki, Raphael Hiesgen +6
QUIC experiences a rapid adoption since its standardization in 2021, and hypergiants configure their infrastructure to optimize for QUIC performance. In this paper, we introduce a…
The Race to the Vulnerable: Measuring the Log4j Shell Incident
Raphael Hiesgen, Marcin Nawrocki, Thomas C. Schmidt +1
The critical remote-code-execution (RCE) Log4Shell is a severe vulnerability that was disclosed to the public on December 10, 2021. It exploits a bug in the wide-spread Log4j libra…
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…
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…
A Reproducibility Study of "IP Spoofing Detection in Inter-Domain Traffic"
Jasper Eumann, Raphael Hiesgen, Thomas C. Schmidt +1
IP spoofing enables reflection and amplification attacks, which cause major threats to the current Internet infrastructure. Detecting IP packets with incorrect source addresses wou…
A Configurable Transport Layer for CAF
Raphael Hiesgen, Dominik Charousset, Thomas C. Schmidt
The message-driven nature of actors lays a foundation for developing scalable and distributed software. While the actor itself has been thoroughly modeled, the message passing laye…
OpenCL Actors - Adding Data Parallelism to Actor-based Programming with CAF
Raphael Hiesgen, Dominik Charousset, Thomas C. Schmidt
The actor model of computation has been designed for a seamless support of concurrency and distribution. However, it remains unspecific about data parallel program flows, while ava…
Revisiting Actor Programming in C++
Dominik Charousset, Raphael Hiesgen, Thomas C. Schmidt
The actor model of computation has gained significant popularity over the last decade. Its high level of abstraction makes it appealing for concurrent applications in parallel and…
