ARIstoteles -- Dissecting Apple's Baseband Interface
Tobias Kröll, Stephan Kleber, Frank Kargl +2
Wireless chips and interfaces expose a substantial remote attack surface. As of today, most cellular baseband security research is performed on the Android ecosystem, leaving a hug…
Evaluating the Reliability and Fidelity of Automated Judgment Systems of Large Language Models
Tom Biskupski, Stephan Kleber
A Large Language Model (LLM) as judge evaluates the quality of victim Machine Learning (ML) models, specifically LLMs, by analyzing their outputs. An LLM as judge is the combinatio…
Refining Network Message Segmentation with Principal Component Analysis
Stephan Kleber, Frank Kargl
Reverse engineering of undocumented protocols is a common task in security analyses of networked services. The communication itself, captured in traffic traces, contains much of th…
Network Message Field Type Classification and Recognition for Unknown Binary Protocols
Stephan Kleber, Milan Stute, Matthias Hollick +1
Reverse engineering of unknown network protocols based on recorded traffic traces enables security analyses and debugging of undocumented network services. In particular for binary…
Analysis of the DoIP Protocol for Security Vulnerabilities
Patrick Wachter, Stephan Kleber
DoIP, which is defined in ISO 13400, is a transport protocol stack for diagnostic data. Diagnostic data is a potential attack vector at vehicles, so secure transmission must be gua…
Message Type Identification of Binary Network Protocols using Continuous Segment Similarity
Stephan Kleber, Rens Wouter van der Heijden, Frank Kargl
Protocol reverse engineering based on traffic traces infers the behavior of unknown network protocols by analyzing observable network messages. To perform correct deduction of mess…
An SDN-based Approach For Defending Against Reflective DDoS Attacks
Thomas Lukaseder, Kevin Stölzle, Stephan Kleber +2
Distributed Reflective Denial of Service (DRDoS) attacks are an immanent threat to Internet services. The potential scale of such attacks became apparent in March 2018 when a memca…
