In a new paper in Nature, a team of researchers from JPMorganChase, Quantinuum, Argonne National Laboratory, Oak Ridge National Laboratory and The University of Texas at Austin describe a milestone in the field of quantum computing, with potential applications in cryptography, fairness and privacy.

Using a 56-qubit quantum computer, they have for the first time experimentally demonstrated certified randomness, a way of generating random numbers from a quantum computer and then using a classical supercomputer to prove they are truly random and freshly generated. This could pave the way toward the use of quantum computers for a practical task unattainable through classical methods.

Scott Aaronson, Schlumberger Centennial Chair of Computer Science and director of the Quantum Information Center at UT Austin, invented the certified randomness protocol that was demonstrated. He and his former postdoctoral researcher, Shih-Han Hung, provided theoretical and analytical support to the experimentalists on this latest project.

In an era where data privacy concerns loom large, a new approach in artificial intelligence (AI) could reshape how sensitive information is processed.

Researchers Austin Ebel and Karthik Garimella, Ph.D. students, and Assistant Professor of Electrical and Computer Engineering Brandon Reagen have introduced Orion, a novel framework that brings fully (FHE) to deep learning—allowing AI models to practically and efficiently operate directly on encrypted data without needing to decrypt it first.

The implications of this advancement, published on the arXiv preprint server and scheduled to be presented at the 2025 ACM International Conference on Architectural Support for Programming Languages and Operating Systems, are profound.

Such credentials could be obtained from a data breach of a social media service or be acquired from underground forums where they are advertised for sale by other threat actors.

Credential stuffing is also different from brute-force attacks, which revolve around cracking passwords, login credentials, and encryption keys using a trial and error method.

Atlantis AIO, per Abnormal Security, offers threat actors the ability to launch credential stuffing attacks at scale via pre-configured modules for targeting a range of platforms and cloud-based services, thereby facilitating fraud, data theft, and account takeovers.

Quantum physics just took a leap from theory to reality! Empa researchers have, for the first time, successfully built a long-theorized one-dimensional alternating Heisenberg model using synthetic nanographenes.

By precisely shaping these tiny carbon structures, they’ve unlocked new ways to manipulate quantum states, confirming century-old predictions. This breakthrough could be a stepping stone toward real-world quantum technologies, from ultra-fast computing to unbreakable encryption.

A hospital that wants to use a cloud computing service to perform artificial intelligence data analysis on sensitive patient records needs a guarantee those data will remain private during computation. Homomorphic encryption is a special type of security scheme that can provide this assurance.

The technique encrypts data in a way that anyone can perform computations without decrypting the data, preventing others from learning anything about underlying patient records. However, there are only a few ways to achieve homomorphic encryption, and they are so computationally intensive that it is often infeasible to deploy them in the real world.

MIT researchers have developed a new theoretical approach to building homomorphic encryption schemes that is simple and relies on computationally lightweight cryptographic tools. Their technique combines two tools so they become more powerful than either would be on its own. The researchers leverage this to construct a “somewhat homomorphic” encryption scheme—that is, it enables users to perform a limited number of operations on encrypted data without decrypting it, as opposed to fully homomorphic encryption that can allow more complex computations.

The Akira ransomware gang was spotted using an unsecured webcam to launch encryption attacks on a victim’s network, effectively circumventing Endpoint Detection and Response (EDR), which was blocking the encryptor in Windows.

Cybersecurity firm S-RM team discovered the unusual attack method during a recent incident response at one of their clients.

Notably, Akira only pivoted to the webcam after attempting to deploy encryptors on Windows, which were blocked by the victim’s EDR solution.
