We evaluate HYPERDEGRADE on different Intel microarchitectures, yielding significant slowdowns that achieve, in select microbenchmark cases, three orders of magnitude improvement over state-of-the-art. To evaluate the efficacy of performance degradation in side-channel amplification, we propose and evaluate leakage assessment metrics. The results evidence that HYPERDEGRADE increases time granularity without a meaningful impact on trace quality. Additionally, we designed a fair experiment that compares three performance degradation strategies when coupled with FLUSH+RELOAD from an attacker perspective. We developed an attack on an unexploited vulnerability in OpenSSL in which HYPERDEGRADE excels—reducing by three times the number of required FLUSH+RELOAD traces to succeed.

COMRace automatically synthesizes 234 PoCs for 256 selected method pairs with conflict accesses, and there are 194 PoCs triggering race conditions. Furthermore, 145 PoCs lead to critical memory corruptions, exposing 26 vulnerabilities confirmed by the Common Vulnerabilities and Exposures database. In this work, we take shuffling technique as a key to design PSU protocols for the first time.

History of the Ilocano People

Despite this, VPNs are still undefended against these attacks, leaving millions of users vulnerable. Proposed defences against website fingerprinting require cooperation between the client and a remote endpoint to reshape the network traffic, thereby hindering deployment. In this work, we aim to bridge the gap by introducing novel poisoning attacks to LDP protocols for key-value data.

Recent work largely improves the efficiency of those attacks, demonstrating their practicality on today's ML-as-a-service platforms. In this work, we explore the feasibility of using a new execution context, the service worker context, as a platform for web security defense development that is programmable, browser agnostic, and runs at the client side without user involvement. To this end, we propose and develop SWAPP , a framework for implementing security mechanisms inside a service worker. As the service worker is supported by most browsers, our framework is compatible with most clients.

DeepDi: Learning a Relational Graph Convolutional Network Model on Instructions for Fast and Accurate Disassembly

The Ilocano feast is often a multipurpose gathering, commemorating the day of the patron saint, a baptism, a housewarming, a bienvenida , a wedding, or a class reunion. The delightful customs, folk songs, and delicacies come to the fore with the verbal battle of metaphors and folk wisdom through the bukanegan and the more stylized dallot, which is partly sung and declaimed, on such a feast day. The smaller hometown band members, whose instruments are usually inherited from their fathers, are invited to weddings, religious processions, and funerals. The kutibeng is now a cherished artifact displayed in museums, but the bamboo flute is still heard in the hilly areas of Ilocos, along with the heirloom gongs that accompany the tadek dance in interior towns like Cervantes or San Emilio in Ilocos Sur.

Exploiting this vulnerability often requires sophisticated property-oriented programming to shape an injection object. Existing off-the-shelf tools focus only on identifying potential POI vulnerabilities without confirming the presence of any exploit objects. To this end, we propose FUGIO, the first automatic exploit generation tool for POI vulnerabilities. FUGIO conducts coarse-grained static and dynamic program analyses to generate a list of gadget chains that serve as blueprints for exploit objects.

Network Security IV

One draws on traditional formal methods to produce mathematical, machine-checked proofs of safety. The second carefully embeds Wasm semantics in safe Rust code such that the Rust compiler can emit safe executable code with good performance. Our implementation and evaluation of these two techniques indicate that leveraging Wasm gives us provably-safe multilingual sandboxing with performance comparable to standard, unsafe approaches. Multi-Server Private Information Retrieval is a cryptographic protocol that allows a client to securely query a database entry from n ≥ 2 servers of which less than t can collude, s.t. Highly efficient PIR could be used for large-scale applications like Compromised Credential Checking (USENIX Security'19), which allows users to check whether their credentials have been leaked in a data breach.

To identify them, we developed a novel NLP/ML pipeline that utilizes a small set of positively labeled CRs to recover 1,270 high-confidence SR-CRs. Our measurement on them reveals serious consequences of specification errors and their causes, including design errors and presentation issues, particularly the pervasiveness of inconsistent descriptions in security-relevant content. Also important is the discovery of a security weakness inherent to the 3GPP ecosystem, which publishes an SR-CR long before the specification has been fixed and related systems have been patched. Interestingly, we found that some recently reported vulnerabilities are actually related to the CRs published years ago. Further, we identified a set of vulnerabilities affecting major carriers and mobile phones that have not been addressed even today.

ProFactory: Improving IoT Security via Formalized Protocol Customization

We demonstrate this process by prototyping the first browser-based ZombieLoad attack and deriving a vanilla JavaScript and WebAssembly PoC running in an unmodified recent version of Firefox. We discuss how libtea and SCFirefox contribute to the security landscape by providing attack researchers and defenders with frameworks to prototype attacks and assess their feasibility. A large body of research in network and social sciences studies the effects of interventions in network systems. Nearly all of this work assumes that network participants will respond to interventions in similar ways.

Lincoln suspended the writ of habeas corpus where needed for the security of troops trying to reach Washington. John Merryman, one Maryland official hindering the U.S. troop movements, petitioned Supreme Court Chief Justice Roger B. Taney to issue a writ of habeas corpus. In June, in Ex parte Merryman, Taney, not ruling on behalf of the Supreme Court, issued the writ, believing that Article I, section 9 of the Constitution authorized only Congress and not the president to suspend it. On April 15, Lincoln called on the states to send a total of 75,000 volunteer troops to recapture forts, protect Washington, and "preserve the Union", which, in his view, remained intact despite the seceding states. Virginia seceded and was rewarded with the designation of Richmond as the Confederate capital, despite its exposure to Union lines. Secession sentiment was strong in Missouri and Maryland, but did not prevail; Kentucky remained neutral.

To allow VMs to communicate with their environment, hypervisors provide a slew of virtual-devices including network interface cards and performance-optimized VIRTIO-based SCSI adapters. Prior works applied fuzzing to simple virtual-devices, focusing on a narrow subset of the vast input-space and the state-of-the-art virtual-device fuzzer, Nyx, requires precise, manually-written, specifications to exercise complex devices. In this paper we propose, design and evaluate a systematic directed fuzzing framework to automatically discover implementation bugs in arbitrary Bluetooth Classic devices. The core of our fuzzer is the first over-the-air approach that takes full control of the BT controller baseband from the host. This enables us to intercept and modify arbitrary packets, as well as to inject packets out-of-order in lower layers of closed-source BT stack, i.e., Link Manager Protocol and Baseband.

They are then able to pass on these savings in the form of no-fee or no-minimum-balance products to their customers. Mobile wallets - The unbanked may not have traditional bank accounts but can have verified mobile wallet accounts for shopping and bill payments. Their mobile wallet identity can be used to open a virtual bank account for secure and convenient online banking. This presents a tremendous opportunity that innovation in fintech can solve by speeding up money movement, increasing access to capital, and making it easier to manage business operations in a central place. Fintech offers innovative products and services where outdated practices and processes offer limited options. We advocate for modernized financial policies and regulations that allow fintech innovation to drive competition in the economy and expand consumer choice.
