Furthermore, we prototyped Silhouette-Invert, an alternative implementation of Silhouette, which incurs just 0.3% and 1.9% performance overhead, at the cost of a minor hardware change. First, it breaks down large—tens of millions of lines—systems into small pieces using user-extensible static checkers to quickly find and mark potential errorsites. In this work, we present Walking Onions, a set of protocols improving scalability for anonymity networks. Machine learning has made remarkable progress in the last years, yet Session Chair: Jelena Mirkovic, USC/Information Sciences Institute, Markus Legner, Tobias Klenze, Marc Wyss, Christoph Sprenger, and Adrian Perrig, ETH Zurich. We find that enhanced protections on mobile devices and the expansion of evidence-based reporting protocols are critical ecosystem improvements that could better protect users against modern phishing attacks, which routinely seek to evade detection infrastructure. (a) tools and resources to learn the model, and (b) a user-friendly query interface to access the model. Nevertheless, recent attacks have exploited these leakages to recover the plaintext database or the posed queries, casting doubt to the usefulness of SE in encrypted systems. Session Chair: Adam Doupé, Arizona State University, Peiyuan Zong, Tao Lv, Dawei Wang, Zizhuang Deng, Ruigang Liang, and Kai Chen, SKLOIS, Institute of Information Engineering, Chinese Academy of Sciences, Beijing, China. In addition to the attacks, we discuss several countermeasures. An empirical risk assessment on real-world binaries and SPEC CPU programs compiled to WebAssembly shows that our attack primitives are likely to be feasible in practice. Joel Frank, Cornelius Aschermann, and Thorsten Holz, Ruhr-University Bochum. non-random character distributions and identifying instances where generated passwords were vulnerable to online and offline guessing attacks. Sessions Chairs: Lucas Davi, Universität Duisburg-Essen; Ahmad-Reza Sadeghi, Technische Universität Darmstadt, Ghada Dessouky, Tommaso Frassetto, and Ahmad-Reza Sadeghi, Technische Universität Darmstadt. Membership inference (MI) attacks exploit the fact that machine learning algorithms sometimes leak information about their training data through the learned model.

Many prior studies have shown external attacks such as adversarial examples that tamper the integrity of DNNs using maliciously crafted inputs. The key idea behind our attack is to undervolt a physical core to force non-recoverable hardware faults. Similarly, DANE clients (e.g., SMTP clients) must verify the DANE servers’ TLSA records, which are also used to validate the fetched certificates. Here we bridge this gap by conducting the first systematic study on the security of interpretable deep learning systems (IDLSes). Many companies provide neural network prediction services to users for a wide range of applications. Our evaluation on ten open-source systems has shown that, i) MVP significantly outperformed state-of-the-art clone-based and function matching-based recurring vulnerability detection approaches; ii) MVP detected recurring vulnerabilities that cannot be detected by general-purpose vulnerability detection approaches, i.e., two learning-based approaches and two commercial tools; and iii) MVP has detected 97 new vulnerabilities with 23 CVE identifiers assigned. Session Chair: Martina Lindorfer, Technische Universität Wien, Yizheng Chen, Shiqi Wang, Dongdong She, and Suman Jana, Columbia University. However, no prior work has studied whether today's MSF algorithms are indeed sufficiently secure under GPS spoofing, especially in AV settings. Fingerprint authentication has gained increasing popularity on mobile devices in recent years.
