Modern Intel processors, including Raptor Lake and Alder Lake CPUs (i.e., 12th and 13th generation Intel “Core” processors), are vulnerable to a new high-precision Branch Target Injection (BTI) attack called “Indirector.” Discovered by security researchers Luyi Li, Hosein Yavarzadeh, and Dean Tullsen of the University of California, San Diego (UCSD), Indirector exploits vulnerabilities within the Indirect Branch Predictor (IBP) and Branch Target Buffer (BTB). These two critical components in Intel CPUs could be abused to hijack execution and leak sensitive data. This attack represents a significant security threat, bypassing existing protection mechanisms. Full details will be disclosed at the upcoming USENIX Security Symposium in August 2024.

Welcome to the Red Hot Cyber community’s Quantum Technology Group page. The themed group will be lead by industry experts, and will focus on the dissemination and the study of advanced computing solutions based on quantum technology. In particular the applications of Quantum Computing and of Quantum Communication will be explored in various fields, amongst which are cyber security, cryptography, machine learning, and optimisation problems. Several use cases will be analysed in different applicable areas of the national and international landscape, and public and private research activities will be monitored.  The objective is to share the real state of Quantum Computing and

Translator: Tara Lie Signal has announced that it has improved encryption within its messenger application. Its end-to-end communication protocol now uses quantum-resistant cryptographic keys, making it resistant to future attacks by quantum computers. Quantum computers – that at the moment do not have concrete applications, as we saw in the interview with Prof. Morello from the ARC Center of Excellence for Quantum Computation in the University of New South Wales in Australia and from Prof. Severini, director of quantum technologies at Amazon Web Services (AWS) – have the potential to be much more powerful and efficient than current systems, allowing them to

This OS is used across the world, and is so versatile that it can be used on any type of device or electronic calculator. The first release of Unix was implemented in the distant year of 1969, where one of its capabilities was to be able to run a video game called “Space Travel”.  The game was a simulation of the movements of the Sun and planets, with a spaceship that could land on these places. The researcher behind this was

Author: Massimiliano BrolliOriginal Publication Date: 12/12/2020Translator: Tara Lie Pier Giorgio Perotto (for those who do not know of him) was an Italian electronics pioneer. In the 60’s he worked for Olivetti, and led the team that built the Olivetti Programma 101 (P101), the first desktop computer in history. The P101, also known as the Perottina, was launched at the 1964 New York World Fair, and was even used by NASA to plan and calculate the space program’s orbits, including the Apollo 11 mission that took man to the moon. For those who would like more details on the Olivetti Programma 101, you can

This computer conference was pivotal for the future of modern computing, and attended by people who would the next year see the moon landing live.  Consider this, before the presentation many in the computing community were whispering in the room, saying that Engelbart was crazy. However, by the time the demonstration ended, some were saying that

Vannevar Bush The essay, written in 1945 by Vannevar Bush, was published in the journal Atlantic Monthly. It introduced science to a new way of thinking, making it clear that for years, all inventions had only taken the extent of humankind’s physical powers into consideration, rather than the power of their minds. Vannevar Bush was an American engineer, born on

Author: Antonio Piovesan Great Britain, middle decades of the 19th century, times of unprecedented engineering ambitions. Engineering, transportation, communications, architecture, science and manufacturing are in a feverish state of evolution. Inventors and engineers exploit new materials and new processes: it seems to be a period of endless inventions and innovations. Steam engines are slowly replacing animals as a source of motive power. Iron ships begin to compete with sailing, rail networks expand rapidly, and the electric telegraph begins to revolutionize communications. Thriving science, engineering and new technologies guarantee limitless innovations.
