In the past several years, researchers from multiple communities—such as security, database, and theoretical computer science—have proposed many LDP protocols. , by Samsung), we find that the delays of patches are largely due to the current patching practices and the lack of knowledge about which USENIX is committed to Open Access to the research presented at our events. While fuzz testing proved to be a very effective technique to find software bugs, open challenges still exist. A kernel data race is notoriously challenging to detect, reproduce, and diagnose, mainly caused by nondeterministic thread interleaving. Three states—Delaware, West Virginia, and New Jersey—recently announced that they would allow certain voters to cast votes online using OmniBallot, but, despite the well established risks of Internet voting, the system has never before undergone a public, independent However, their pervasiveness also amplifies the impact of security vulnerabilities. , buffer overflow), creating a gap whereby bug reports received by developers contain (at best) a snapshot of the process long after it executed the buggy instructions. Papers and proceedings are freely available to everyone once the event begins. An Empirical Study of Rust-for-Linux: The Success, Dissatisfaction, and Compromise USENIX Security '23. 2% overhead (8. Hence, the security of RDMA architectures is crucial, yet potential security implications of using RDMA communication remain largely unstudied. Glaze: Protecting Artists from Style USENIX is committed to Open Access to the research presented at our events. The continuing use of proprietary cryptography in embedded systems across many industry verticals, from physical access control systems and telecommunications to machine-to-machine authentication, presents a significant obstacle to black-box security-evaluation efforts. The EOSIO blockchain, one of the representative Delegated Proof-of-Stake (DPoS) blockchain platforms, has grown rapidly recently. C, . Outside the browser, Wasm has become a popular lightweight, in-process sandbox and is, for example, used in production to isolate different clients on edge clouds and function-as-a-service platforms. A recent cryptographic solution Delphi (Usenix Security 2020) strives for low latency by using GPU on linear layers and replacing some non-linear units in the model at a price of accuracy. USENIX is committed to Open Access to the research presented at our events. Disrupting Continuity of Apple's Wireless Ecosystem Security: New Tracking, DoS, and MitM Attacks on iOS and macOS Through Bluetooth Low Energy, AWDL, and Wi-Fi Authors: Milan Stute, Alexander Heinrich, Jannik Lorenz, and Matthias Hollick, Technical University of Darmstadt Known approaches for using decoy passwords (honeywords) to detect credential database breaches suffer from the need for a trusted component to recognize decoys when entered in login attempts, and from an attacker's ability to test stolen passwords at other sites to identify user-chosen passwords based on their reuse at those sites. , wormhole attacks), staggered collateral (i. In our evaluation of the attacks in the Internet we find that all the standard compliant open DNS resolvers we tested allow our injection attacks against applications Distinguished Paper Award Winner and Second Prize winner of the 2021 Internet Defense Prize Abstract: Semi-supervised machine learning models learn from a (small) set of labeled training examples, and a (large) set of unlabeled training examples. Date/Time Aug. 7% overhead, adding protection for data in registers at 22. Meanwhile, a number of vulnerabilities and high-profile attacks against top EOSIO DApps and their smart contracts have also been discovered and observed in the wild, resulting in serious financial damages. 3-A general purpose hardware mechanism for pointer authentication (PA) to implement ACS. Although SDN can improve network security oversight and policy enforcement, ensuring the security of SDN from sophisticated attacks is an ongoing challenge for practitioners. Our findings underscore the importance of more holistic design of security tools to address both online and offline axes of safety. However, recently reported attacks on such tokens suggest that users cannot take the security guarantees of their HSTs for granted, even despite widely deployed authenticity checks. Finally, we use a state-of-the-art formal verification tool, Tamarin prover, to prove that 5G-AKA′ achieves the desired security goals of privacy, authentication and secrecy. Albeit their popularity, little has been done to evaluate their security and associated risks. This provides us an opportunity to build a unified and generic security framework defending against multiple kinds of UV attacks by monitoring the system's I/O activities. Reiter, Duke In this work, we investigate where Internet services are deployed in practice and evaluate the security posture of services on unexpected ports. Like most modern software systems, IoT device firmware depends on external third-party libraries extensively, increasing the attack surface of IoT devices. We show protocol deployment is more diffuse than previously believed and that protocols run on many additional ports beyond their primary IANA-assigned port.

Our attack enables a malicious client to learn model weights with 22x--312x fewer queries than the best black-box model-extraction attack and USENIX is committed to Open Access to the research presented at our events. Finally, we suggest concrete directions for future work on encouraging digital security behavior through security prompts. Based on our results, we distill a set of best-practice design patterns for most effectively encouraging protective behavior through carefully communicating with users about 2FA. Provenance-based analysis techniques have been proposed as an effective means toward comprehensive and high-assurance security control as they provide fine-grained mechanisms to track data flows across the system USENIX is committed to Open Access to the research presented at our events. Join us in Vancouver The final responsibility to verify whether a newly purchased hardware security token (HST) is authentic and unmodified lies with the end user. Thus, it depends on the weakest link of the chain, as any failed part can break the whole chain-based defense. , encoding explicit dependencies among syscalls), and (3) behaviors of inputs (i. Recent progress in interactive zero-knowledge (ZK) proofs has improved the efficiency of proving large-scale computations significantly. Recent work showed that blind fuzzing is the most efficient approach to identify security issues in hypervisors, mainly due to an outstandingly high test throughput. An email's authenticity is based on an authentication chain involving multiple protocols, roles and services, the inconsistency among which creates security threats. These studies mainly focused on improving the utility of the LDP protocols. It can handle a query on CIFAR-100 with ~68% accuracy in 14s or ~66% accuracy in 2.

The 30th USENIX Democracy Live's OmniBallot platform is a web-based system for blank ballot delivery, ballot marking, and online voting. , funds are locked for a time proportional to the payment path length) and dependency on specific scripting language functionality (e. (SOUPS '19) highlighted the motivations and barriers to adopting PMs. Directed greybox fuzzing is an augmented fuzzing technique intended for the targeted usages such as crash reproduction and proof-of-concept generation, which gives directedness to fuzzing by driving the seeds toward the designated program locations called target sites. 6–42. In this paper, we propose ELISE, a storage efficient logging system built on top of a novel lossless data compression technique, which naturally supports all types of End-host runtime monitors (e. Route hijacking is one of the most severe security problems in today's Internet, and route origin hijacking is the most common. Existing network forensics tools attempt to identify and track such attacks, but holistic causal reasoning across control and data planes remains challenging. Password managers (PMs) are considered highly effective tools for increasing security, and a recent study by Pearman et al. 1 Cheng Guo and Brianne Campbell, Clemson University; Apu Kapadia, Indiana University; Michael K. While origin hijacking detection systems are already available, they suffer from tremendous pressures brought by frequent legitimate Multiple origin ASes (MOAS) conflicts. Unfortunately, existing vulnerability detection methods cannot effectively nor efficiently analyze such web services: they either introduce heavy execution overheads or Our prototype, PACStack, uses the ARMv8. Many popular vulnerabilities of embedded systems reside in their vulnerable web services. A Large-Scale Interview Study on Information Security in and Attacks against Small and Medium-sized Enterprises. , invalid control transfer) may occur long after the root cause (e. The kernel data race has a critical security implication since it often leads to memory corruption, which can be abused to launch privilege escalation attacks. In this work, we aim to bridge this gap. To proactively address the problem, we propose a systematic evaluation of Android SmartTVs security. Liu}, title = {Automated Discovery of {Denial-of-Service} Vulnerabilities in Connected Vehicle Protocols}, Fuzzing embeds a large number of decisions requiring finetuned and hard-coded parameters to maximize its efficiency. Hence, the efficient detection of hypervisor vulnerabilities is crucial for the security of the modern cloud infrastructure. Schwartz, Bogdan Vasilescu By analyzing the CVEs and patches available since the inception of the Android security bulletin, as well as open-source upstream kernels (e. , Hash Time-Lock Contracts) that hinders a wider deployment in Password security hinges on an in-depth understanding of the techniques adopted by attackers. This is especially true for kernel fuzzing due to (1) OS kernels' sheer size and complexity, (2) a unique syscall interface that requires special handling (e.
