The majority of advice is perceived by the most users to be at least somewhat actionable, and somewhat comprehensible. Moreover, the state-of-the-art and new adaptive evolutionary attackers need up to 10 times larger $L_0$ feature distance and 21 times more PDF basic mutations (e.g., inserting and deleting objects) to evade our robust model than the baselines. Firewall policies are restricted to coarse-grained features that are easy to evade and mimic, such as protocols or port numbers. Our research demonstrates the serious consequences of these exploits and the security implications of the practice today for building these mechanisms. We propose NetWarden, a novel defense whose key design goal is to preserve TCP performance while mitigating covert channels. In USENIX Security Symposium. By all accounts, the 2020 election will be historic. Atri Bhattacharyya. Third, we deploy these measurement approaches to evaluate the 374 unique pieces of security advice in a user-study with 1,586 users and 41 professional security experts. We deployed DELF in three distinct OSNs, showing the feasibility of our approach. In this paper, we propose POLICHECK, which formalizes and implements an entity-sensitive flow-to-policy consistency model. Alex Ozdemir and Riad Wahby, Stanford University; Barry Whitehat, Unaffiliated; Dan Boneh, Stanford University. We present BlockSci, an open-source software platform for blockchain analysis. The strongest threat model for voting systems considers coercion resistance: protection against coercers that force voters to modify their votes, or to abstain. So far, AVs tend to trust the information provided by their sensors to make navigation decisions without data validation or verification, and therefore, attackers can exploit these limitations by feeding erroneous sensor data with the intention of disrupting or taking control of the system. To make things worse, modern firmware contains millions of lines of unnecessary code and hundreds of unnecessary modules as a result of a long firmware supply chain designed to optimize time-to-market and cost, but not security. Technically, such data flows are not “leaks” if they are disclosed in a privacy policy. In particular, current code review is prone to miss less obvious side channels hidden deeply in the call stack. achieve 100% success in It reports 317 alerts which are caused by 50 unique bugs in terms of the root causes. biometric fingerprint software deployed on popular laptop brands. In DELF, developers specify deletion annotations on data type definitions, which the framework maps into asynchronous, reliable and temporarily reversible operations on backing data stores. Our evaluation is the first analysis of password generation in password managers, finding several Smartphone applications that listen for network connections introduce significant security and privacy threats for users. Politehnica Bucharest; Rob Taglang, Private Machines; Mihai Chiroiu, Univ. In light of this, we present BScout, which directly checks the presence of a whole patch in Java executables without generating signatures. Xander Bouwman, Delft University of Technology, the Netherlands; Harm Griffioen, Hasso Plattner Institute, University of Potsdam, Germany; Jelle Egbers, Delft University of Technology, the Netherlands; Christian Doerr, Hasso Plattner Institute, University of Potsdam, Germany; Bram Klievink, Leiden University, the Netherlands; Michel van Eeten, Delft University of Technology, the Netherlands. Finally, to understand the key features learned by FuzzGuard, we illustrate their connection with the constraints in the programs. In particular, it involves various mechanisms that interact with each other in subtle ways, which offers little hope for modular reasoning. Dynamic testing or fuzzing of embedded firmware is severely limited by hardware-dependence and poor scalability, partly contributing to the widespread vulnerable IoT devices. Hui Peng, Purdue University; Mathias Payer, EPFL. In particular, we expand DATA, an open-source side-channel analysis framework, to detect nonce leakage. We evaluate it on 6 real-world sensor traces, and find that FusionRipper can achieve at least 97% and 91.3% success rates in all traces for off-road and wrong-way attacks respectively. Their wide attack surface, exposed via both the system call interface and the peripheral interface, is often found to be the most direct attack vector to compromise an OS kernel. We focus on the effects of blocking contextual ads (ads targeted to individual, potentially sensitive, contexts, such as search queries in a search engine or the content of web pages) on how participants searched for and purchased various products online, and the resulting consumer welfare. Session Chairs: Carmela Troncoso, École Polytechnique Fédérale de Lausanne (EPFL); Rob Jansen, U.S. Trusted Execution Environments (TEEs) use hardware-based isolation to guard sensitive data from conventional monolithic OSes. In six experiment deployments over nine months, we systematically launch and report 2,862 new (innocuous) phishing websites to evaluate the performance (speed and coverage) and consistency of blacklists, with the goal of improving them. Fuzzing is one of the most popular vulnerability discovery solutions, yet faces several challenges when applied to Android native system services. Because TrustZone has access to sensitive information such as cryptographic keys, access to TrustZone has been locked down on real-world devices: only code that is authenticated by a trusted party can run in TrustZone. Yet, both users and experts struggle to prioritize this advice. Crucially, participants found these understudied practices among the most privacy invasive. Ben Adida is the Executive Director of VotingWorks, the only non-profit election equipment vendor in the United States, with a mission is to rebuild citizen trust in US elections with secure and affordable voting equipment. Instead of setting a pre-defined set of functionalities, TXSPECTOR allows users to specify customized rules to uncover various types of attacks in the transactions. Servers never store full client public keys but work on parts provided by the clients, without having to maintain any per-client state. These approaches are implemented on top of AFL in an adaptive energy-saving greybox fuzzer called EcoFuzz. Google Scholar Security of machine learning is increasingly becoming a major concern due to the ubiquitous deployment of deep learning in many security-sensitive domains. We show that frequency smoothing prevents access pattern leakage attacks by passive persistent adversaries in a new formal security model. Furthermore, we explore WCD in a scientific framework as an instance of the path confusion class of attacks, and demonstrate that variations on the path confusion technique used make it possible to exploit sites that are otherwise not impacted by the original attack. Session Chair: Zakir Durumeric, Stanford University, Samuel Weiser, David Schrammel, and Lukas Bodner, Graz University of Technology; Raphael Spreitzer, SGS Digital Trust Services. We present novel static analysis techniques for improving the precision of extracting the application's call graph for each execution phase, which is then used to pinpoint the system calls used in each phase. However, little work has been done to understand the way reverse engineers think when analyzing programs, leaving tool developers to make interface design decisions based only on intuition. In several cases, copies of the same private key have been imported in the ID cards of different cardholders, allowing them to impersonate each other. We then trace the program's states while executing each found input and generate predicates, i.e., simple Boolean expressions that capture behavioral differences between crashing and non-crashing inputs. Therefore, the same attacks that have been practical on MD5 since 2009 are now practical on SHA-1. BesFS comprises of 15 APIs with compositional safety and is expressive enough to support 31 real applications we test. We implemented a prototype of FANS from scratch and evaluated it on six smartphones equipped with a recent version of Android, i.e., android-9.0.0_r46 , and found 30 unique vulnerabilities deduplicated from thousands of crashes, of which 20 have been confirmed by Google. We present DatashareNetwork, a decentralized and privacy-preserving search system that enables journalists worldwide to find documents via a dedicated network of peers. However, this performance metric is considering only CPU time and ignoring bandwidth and storage. ShadowMove is enabled by a novel socket duplication approach that allows a malicious process to silently abuse TCP connections established by benign processes. With the growing trend of the Internet of Things, a large number of wireless OBD-II dongles are developed, which can be simply plugged into vehicles to enable remote functions such as sophisticated vehicle control and status monitoring. To our knowledge, this is the first work to automatically derive such complex chosen ciphertext attacks. For OSNs, robust deletion is both an obligation to their users and a risk when developer mistakes inevitably occur. ): for example, Philips Hue and SmartThings clouds support to delegate device access to another cloud such as Google Home, so a user can manage multiple devices from different vendors all through Google Home. Intra-process memory isolation can improve security by enforcing least-privilege at a finer granularity than traditional operating system controls without the context-switch overhead associated with inter-process communication. VirusTotal provides malware labels from a large set of anti-malware engines, and is heavily used by researchers for malware annotation and system evaluation. In this work, we consider distributed private learning. state-of-the-art implementations by orders of magnitude. However, achieving such robustness is an extremely challenging task. Sys uses a two-step approach to find such tricky errors. In addition, the commercial power system simulation tool Etap 19.0.1 is used to simulate the impact of the attack on a 2.3 MW power grid. finding, we investigate three popular imaging libraries for machine It also outperforms Qsym, a system that We thus propose recommendations for web developers and browser vendors to mitigate this issue. An isolation domain can include one or more processes, specific portions of code, or a Trusted Execution Environment (e.g., SGX or TrustZone). According to the results, EcoFuzz could attain 214% of the path coverage of AFL with reducing 32% test cases generation of that of AFL. Linked Presentation: BLESA: Spoofing Attacks against Reconnections in Bluetooth Low Energy. Raul Quinonez, University of Texas at Dallas; Jairo Giraldo, University of Utah; Luis Salazar, University of California, Santa Cruz; Erick Bauman, University of Texas at Dallas; Alvaro Cardenas, University of California, Santa Cruz; Zhiqiang Lin, Ohio State University. In these services, the client sends the query to the cloud server and receives the response in which case the query and response are revealed to the service provider. After the 2016 U.S. presidential election, he advised recount initiatives in Michigan, Wisconsin, and Pennsylvania in an effort to help detect and deter cyberattacks, and in 2017 he testified to the U.S. Senate Intelligence Committee Russia investigation about cybersecurity threats to election infrastructure. However, similar to traditional computer programs, smart contracts have vulnerabilities, which can be exploited to cause financial loss of contract owners. Third, users' privacy and security-related behaviors were heavily influenced by living in high-crime areas. Our approach is efficient (practical running time), scaleable (sublinear in the data universe size) and accurate, i.e., the absolute error is smaller than comparable methods and is independent of the number of users, hence, our protocols can be used even for a small number of users. Overall, we found that 1.67% of the 358 applications are not compliant with PCI DSS, with vulnerabilities including improperly storing credit card numbers and card verification codes. In contrast to this trend, a flexible hardware monitor can efficiently enforce and enhance a variety of security policies as security threats evolve. Autonomous vehicles are becoming increasingly popular, but their reliance on computer systems to sense and operate in the physical world introduces new security risks. Samin Yaseer Mahmud and Akhil Acharya, North Carolina State University; Benjamin Andow, IBM T.J. Watson Research Center; William Enck and Bradley Reaves, North Carolina State University. This paper describes the discovery process of these findings and the incident response taken by the authorities. We also demonstrate using PARTEMU to test the QSEE TZOS itself, finding crashes in code paths that would not normally be exercised on a real device. For this purpose, we make the key observation that while the instrumentation performed by existing software sanitizers are regularly used for detecting fuzzer-induced error conditions, they can further serve as a generic and effective mechanism to identify interesting basic blocks for guiding fuzzers. Joel Frank, Cornelius Aschermann, and Thorsten Holz, Ruhr-University Bochum. We propose an innovative controlled-channel attack, named CopyCat, that deterministically counts the number of instructions executed within a single enclave code page. We assume an attacker has compromised some client devices, and the attacker manipulates the local model parameters on the compromised client devices during the learning process such that the global model has a large testing error rate. Linked Presentation: USBFuzz: A Framework for Fuzzing USB Drivers by Device Emulation. Naval Research Laboratory, Frank Li, Georgia Institute of Technology / Facebook. We perform experiments both on academic datasets and a state-of-the-art image classifier trained with 1 billion proprietary images. This interface exposes the OS kernels and device drivers to attacks by malicious devices. Similarly, security testing drivers is challenging as input must cross the hardware/software barrier. We propose a novel privacy-preserving solution for a problem of central importance to software usage analysis: control-flow graph coverage analysis over many deployed software instances. Membuster is qualitatively different from prior on-chip attacks to enclaves and is more difficult to thwart. Specifically, we present ADV2, a new class of attacks that generate adversarial inputs not only misleading target DNNs but also deceiving their coupled interpretation models. thwart its correct operation. Our findings shed light on designing and operating IDLSes in a more secure and informative fashion, leading to several promising research directions. Oleksii Oleksenko and Bohdan Trach, TU Dresden; Mark Silberstein, Technion; Christof Fetzer, TU Dresden. In this paper, we show that the location privacy of an autonomous vehicle may be compromised by software side-channel attacks if localization software shares a hardware platform with an attack program. In this paper, we show that data is partially or completely recoverable from the flash media sanitized with “scrubbing” based technique, which is a popular technique for page deletion in NAND flash. The introduction of smart contracts has significantly advanced the state-of-the-art in cryptocurrencies. There is a cognitive bias in the hacker community to select a piece of software and invest significant human resources into finding bugs in that software without any prior indication of success. Data collection under local differential privacy (LDP) has been mostly studied for homogeneous data. Gaëtan Leurent, Inria, France; Thomas Peyrin, Nanyang Technological University, Singapore. Deep Neural Networks (DNNs) are fast becoming ubiquitous for their ability to attain good accuracy in various machine learning tasks. Besides, EcoFuzz identified 12 vulnerabilities in GNU Binutils and other software. Both of our protocols rely on a new circuit for the approximate top-k selection from n numbers that is built from O(n + k2) comparators. LLVM-based C and C++ compiler that builds concolic execution right into the services. Follow us on Instagram. Prior work on black-box adversarial examples follows one of two main strategies: (1) transfer attacks use white-box attacks on local models to find candidate adversarial examples that transfer to the target model, and (2) optimization-based attacks use queries to the target model and apply optimization techniques to search for adversarial examples. Overall, our findings show a perhaps surprising lack of binary security in WebAssembly. We discuss our methodology and detail how we overcame challenges in reverse-engineering this unpublished application layer protocol, including that all UPI apps undergo a rigorous security review in India and are designed to resist analysis. The attacks violate the privacy goals of these crypto-currencies by exploiting side-channel information leaked by the implementation of different system components. al. In total, Muzz detected eight new concurrency-vulnerabilities and nineteen new concurrency-bugs. We implement our approach in a tool named MVP. Daniel Moghimi, Worcester Polytechnic Institute; Moritz Lipp, Graz University of Technology; Berk Sunar, Worcester Polytechnic Institute; Michael Schwarz, Graz University of Technology. Content Delivery Networks (CDNs) serve a large and increasing portion of today’s web content. the processor to enclave mode which protects it from introspection. CFIXX -- Object Type Integrity for C++. 2015. To apply deep learning with DGF, we design a suite of new techniques (e.g., step-forwarding approach, representative data selection) to solve the problems of unbalanced labeled data and insufficient time in the training process. Specifically, our study decouples two important factors of an adversarial transaction-i.e., (i) an adversarial action exploiting the vulnerable contract and (ii) an adversarial consequence like ether or token transfers resulted from the action-for the analysis of attacks and defenses. magnitude and an average factor of 12. In this paper, we analyze to what extent vulnerabilities are exploitable in WebAssembly binaries, and how this compares to native code. learned) by a dishonest user who interacts with the server only via the query interface. Yet, we lack a deep understanding of its purported security and privacy contributions, particularly in today's web ecosystem, where modern browsers provide potential alternative mechanisms for protecting link navigations without link shimming's costs. For example, simple mistakes were least common: only 21% of projects introduced such an error. Yet, its underlying mechanism, deep learning-based text classification (DLTC), is inherently vulnerable to maliciously crafted adversarial texts. Statut: Staff, EPFL school of computer and communication sciences (IC), Topics in Language-based Software Security. Finally, we demonstrate OWL's performance through experiments, case studies, and qualitative analysis. Complex systems will always have exploitable bugs, we systematically analyze potential threats and attack vectors. We develop a unique framework—Golden Hour—that allows us to passively measure victim traffic to phishing pages while proactively protecting tens of thousands of accounts in the process. enclave binary code for vulnerabilities introduced at the host-to-enclave In particular, we discovered timing leakage on an Intel firmware-based TPM as well as a hardware TPM. Second, end hosts should be able to verify that their forwarding decisions are actually followed by the network. Through extensive evaluations on four benchmark systems and against various adversarial settings, our proposed defense shows desirable robustness as if the systems were under no attacks, even in some case when 90% Byzantine workers are controlled by the adversary. We perform a large-scale analysis of roughly 2.2 million accounts currently active on the blockchain and automatically generate 5,905 valid inputs which trigger a vulnerability. Tenure Track Assistant Professor Mathias Payer. Our experimental results proved that MITM attacks (caused by downgrading) are possible to all these products. We systematically demonstrate our attacks on real systems against 11 DNN architectures with 4 datasets corresponding to different application domains. ARM's TrustZone technology is the basis for security of billions of devices worldwide, including Android smartphones and IoT devices. She was part of the team (with Chris Culnane and Ben Rubinstein) who discovered the easy re-identification of doctors and patients in the Medicare/PBS open dataset released by the Australian Department of Health. This session is a great opportunity to interact with the organizers and the participants of the competition and get a feel for the hardware side of the security! Defenses against such leakage-abuse attacks typically require the use of Oblivious RAM or worst-case padding---such countermeasures are however quite impractical. Due to our correlated key and value perturbation mechanisms, the composed privacy budget is shown to be less than that of independent perturbation of key and value, which enables us to further optimize the perturbation parameters via budget allocation. The resulting assembly code has accurate symbolic information, providing cross-references for analysis and to enable adjustment of code and data pointers to accommodate rewriting. In an extreme version of the attack, the flaws could allow a victim's bank account to be linked and emptied, even if a victim had never used a UPI app. We present SENG, a network gateway that enables firewalls to reliably attribute traffic to an application. We present a new paradigm, programmable in-network security (Poise), which is enabled by the emergence of programmable switches. The flaws have been discovered by analyzing public-key certificates that have been collected from the public ID card certificate repository. First, we compare against the eight aforementioned tools, showing that even relatively simple toy examples can obstruct other analyzers. To defeat security threats such as man-in-the-middle (MITM) attacks, Bluetooth Low Energy (BLE) 4.2 and 5.x introduced a Secure Connections Only (SCO) mode, under which a BLE device can only accept secure pairing such as Passkey Entry and Numeric Comparison from an initiator, e.g., an Android mobile. While the number of IoT devices grows at an exhilarating pace their security remains stagnant. Our results show that MaxFetch(1) degrades neither the recursive resolver throughput nor its latency. Statut: Staff, EPFL IC IC-SIN SIN-ENS Extensive evaluations show that it outperforms both existing methods and the industry-leading platforms. With DongleScope, we have identified 5 different types of vulnerabilities, with 4 being newly discovered. We evaluate BScout with 194 CVEs from the Android framework and third-party libraries. Pixel signatures consist of two group elements, regardless of the number of signers, can be verified using three pairings and one exponentiation, and support non-interactive aggregation of individual signatures into a multi-signature. In this work, we present Walking Onions, a set of protocols improving scalability for anonymity networks. Paul Fiterau-Brostean and Bengt Jonsson, Uppsala University; Robert Merget, Ruhr-University Bochum; Joeri de Ruiter, SIDN Labs; Konstantinos Sagonas, Uppsala University; Juraj Somorovsky, Paderborn University. We present a repeatable human study that leverages teams of varying skill while using automation to the greatest extent possible. This programming paradigm, however, creates security concerns due to the potential for inconsistent interpretations of messages between different components. Nathan Burow, Scott A. Carr, Stefan Brunthaler, Mathias Payer, Joseph Nash, Per Larsen, Michael Franz: Control-Flow Integrity: Precision, Security, and Performance. For 98% of the target commands of these devices, our approach can generate at least one AE for attacking the target devices. We aim to provide similar insights in the context of IPS. We need tools to protect ourselves from Dr. Aviel (Avi) D. Rubin is Professor of Computer Science and Technical Director of the Information Security Institute at Johns Hopkins University. New advances in machine learning have made Automated Speech Recognition (ASR) systems practical and more scalable. We discuss the feasibility of using a 100 kW inverter through discussion. We perform the first defense study, proposing CARLO to mitigate LiDAR spoofing attacks. In model Exploiting these vulnerabilities, we design and implement key recovery attacks utilizing signals ranging from electromagnetic (EM) emanations, to granular microarchitecture cache timings, to coarse traditional wall clock timings. This "shimming" of URL clicks can serve navigation security, privacy, and analytics purposes, and has been deployed by prominent websites (e.g., Facebook, Twitter, Microsoft, Google) for over a decade. Xudong Pan, Mi Zhang, Duocai Wu, and Qifan Xiao, Fudan University; Shouling Ji, Zhejiang University/Ant Financial; Min Yang, Fudan University. This interface exposes the OS kernels and device drivers to attacks by malicious devices. The generated fuzzers achieve an average of 54.94% code coverage; an improvement of 6.94% when compared to manually written fuzzers, demonstrating the effectiveness and generality of FuzzGen. Video-analytics-as-a-service is becoming an important offering for cloud providers. It also randomizes the number and distribution of dummy packets for trace-to-trace randomness to impede the attacker’s learning process. As a state-of-the-art coverage-based greybox fuzzer, AFL is a highly effective and widely used technique. We present these ideas in a prototype system, HALucinator, able to re-host firmware, and allow the virtual device to be used normally. Moreover, when testing our chip-based vulnerabilities on those devices, we find BlueFrag, a chip-independent Android RCE. Our results allow us to objectively and automatically associate each informal security level presented in the Noise specification with a formal security claim. For example, when attacking the OpenBLAS library, for the different layers in VGG-16, it reduces the search space from more than 5.4×1012 architectures to just 16; for the different modules in ResNet-50, it reduces the search space from more than 6×1046 architectures to only 512. Click-jacking protection on the modern Web is commonly enforced via client-side security mechanisms for framing control, like the X-Frame-Options header (XFO) and Content Security Policy (CSP).
