AMD has released mitigation and firmware updates to address a high-severity vulnerability that can be exploited to load malicious CPU microcode on unpatched devices.
The security flaw (CVE-2024–56161) is caused by an improper signature verification weakness in AMD’s CPU ROM microcode patch loader.
Attackers with local administrator privileges can exploit this weakness, resulting in the loss of confidentiality and integrity of a confidential guest running under AMD Secure Encrypted Virtualization-Secure Nested Paging (SEV-SNP).
Optical information encoded in holograms is transferred by means of ultrashort laser filaments propagating in highly nonlinear and turbulent media. After propagation, the initial optical information is completely scrambled and cannot be retrieved by any experimental or physical modeling system. Yet, we demonstrate that neural networks trained on experimental data provide a robust way to fully recover the original hologram images. Remarkably, our approach demonstrates the ability to decode intricate spatial information, marking a significant advancement in information retrieval from chaotic media, with applications in secure free-space optical communications and cryptography.
WASHINGTON — As the demand for digital security grows, researchers have developed a new optical system that uses holograms to encode information, creating a level of encryption that traditional methods cannot penetrate. This advance could pave the way for more secure communication channels, helping to protect sensitive data.
“From rapidly evolving digital currencies to governance, healthcare, communications and social networks, the demand for robust protection systems to combat digital fraud continues to grow,” said research team leader Stelios Tzortzakis from the Institute of Electronic Structure and Laser, Foundation for Research and Technology Hellas and the University of Crete, both in Greece.

“Our new system achieves an exceptional level of encryption by utilizing a neural network to generate the decryption key, which can only be created by the owner of the encryption system.”
Their method scrambles laser beams into chaotic patterns, making decryption impossible without a trained neural network. This innovation could revolutionize cryptography.

Quantum computers require extreme cooling to perform reliable calculations. One of the challenges preventing quantum computers from entering society is the difficulty of freezing the qubits to temperatures close to absolute zero.
Now, researchers at Chalmers University of Technology, Sweden, and the University of Maryland, U.S., have engineered a new type of refrigerator that can autonomously cool superconducting qubits to record low temperatures, paving the way for more reliable quantum computation.
Quantum computers have the potential to revolutionize fundamental technologies in various sectors of society, with applications in medicine, energy, encryption, AI, and logistics. While the building blocks of a classical computer—bits—can take a value of either 0 or 1, the most common building blocks in quantum computers—qubits—can have a value of 0 and 1 simultaneously.
The U.S. Department of Health and Human Services (HHS) has proposed updates to the Health Insurance Portability and Accountability Act of 1996 (HIPAA) to secure patients’ health data following a surge in massive healthcare data leaks.
These stricter cybersecurity rules, proposed by the HHS’ Office for Civil Rights (OCR) and expected to be published as a final rule within 60 days, would require healthcare organizations to encrypt protected health information (PHI), implement multifactor authentication, and segment their networks to make it harder for attackers to move laterally through them.
“In recent years, there has been an alarming growth in the number of breaches affecting 500 or more individuals reported to the Department, the overall number of individuals affected by such breaches, and the rampant escalation of cyberattacks using hacking and ransomware,” the HHS’ proposal says.
