Optimal Piecewise-Based Mechanism for Collecting Bounded Numerical Data under Local Differential Privacy

Numerical data with bounded domains is a common data type in personal devices, such as wearable sensors. While the collection of such data is essential for third-party platforms, it raises significant privacy concerns. Local differential privacy LDP has been shown as a framework providing provabl...

CVE-2025-6029 KIA-branded Aftermarket Generic Smart Keyless Entry System Replay Attack

Use of fixed learning codes, one code to lock the car and the other code to unlock it, the Key Fob Transmitter in KIA-branded Aftermarket Generic Smart Keyless Entry System, primarily distributed in Ecuador, which allows a replay attack. Manufacture is unknown at the time of release. CVE Record...

Inside a Dark Adtech Empire Fed by Fake CAPTCHAs

Late last year, security researchers made a startling discovery: Kremlin-backed disinformation campaigns were bypassing moderation on social media platforms by leveraging the same malicious advertising technology that powers a sprawling ecosystem of online hucksters and website hackers. A new...

WordPress Sites Turned Weapon: How VexTrio and Affiliates Run a Global Scam Network

The threat actors behind the VexTrio Viper Traffic Distribution Service TDS have been linked to other TDS services like Help TDS and Disposable TDS, indicating that the sophisticated cybercriminal operation is a sprawling enterprise of its own that's designed to distribute malicious content...

CVE-2025-2254

An issue has been discovered in GitLab CE/EE affecting all versions from 17.9 before 17.10.8, 17.11 before 17.11.4, and 18.0 before 18.0.2. Improper output encoding in the snipper viewer functionality lead to Cross-Site scripting attacks...

Secure Data Access in Cloud Environments Using Quantum Cryptography

Cloud computing has made storing and accessing data easier but keeping it secure is a big challenge nowadays. Traditional methods of ensuring data may not be strong enough in the future when powerful quantum computers become available. To solve this problem, this study uses quantum cryptography t...

Securing Unbounded Differential Privacy against Timing Attacks

Recent works have started to theoretically investigate how we can protect differentially private programs against timing attacks, by making the joint distribution the output and the runtime differentially private JOT-DP. However, the existing approaches to JOT-DP have some limitations, particular...

Stealix: Model Stealing Via Prompt Evolution

Model stealing poses a significant security risk in machine learning by enabling attackers to replicate a black-box model without access to its training data, thus jeopardizing intellectual property and exposing sensitive information. Recent methods that use pre-trained diffusion models for data...

Membership Inference Attacks for Unseen Classes

Shadow model attacks are the state-of-the-art approach for membership inference attacks on machine learning models. However, these attacks typically assume an adversary has access to a background nonmember data distribution that matches the distribution the target model was trained on. We initiat...

Faraday 5.14.1

Faraday is a tool that introduces a new concept called IPE, or Integrated Penetration-Test Environment. It is a multiuser penetration test IDE designed for distribution, indexation and analysis of the generated data during the process of a security audit. The main purpose of Faraday is to re-use...

MULTISS: Un Protocole De Stockage Confidentiel {À} Long Terme Sur Plusieurs R{É}Seaux QKD

This paper presents MULTISS, a new protocol for long-term storage distributed across multiple Quantum Key Distribution QKD networks. This protocol is an extension of LINCOS, a secure storage protocol that uses Shamir secret sharing for secret storage on a single QKD network. Our protocol uses...

Spanning-Tree-Packing Protocol for Conference Key Propagation in Quantum Networks

We consider a network of users connected by pairwise quantum key distribution QKD links. Using these pairwise secret keys and public classical communication, the users want to generate a common conference secret key at the maximal rate. We propose an algorithm based on spanning tree packing a kno...

Quantum Secure Key Exchange with Position-Based Credentials

Quantum key distribution QKD provides an information-theoretic way of securely exchanging secret keys, and typically relies on pre-shared keys or public keys for message authentication. To lift the requirement of pre-shared or public keys, Buhrman et. al. SIAM J. Comput. 43, 150 2014 proposed...

Design, Implementation, and Analysis of Fair Faucets for Blockchain Ecosystems

The present dissertation addresses the problem of fairly distributing shared resources in non-commercial blockchain networks. Blockchains are distributed systems that order and timestamp records of a given network of users, in a public, cryptographically secure, and consensual way. The records,...
