Quantum Computing Isn’t Just Coming for Bitcoin—It Threatens Messaging Apps Too

IBM researchers are collaborating with Signal and Threema to develop messaging systems resilient to quantum computing threats, prompted by concerns that quantum technology could compromise current encryption methods. IBM's report stresses the need to redesign messaging protocols in anticipation of potential quantum capabilities that could break existing encryption. Cryptography expert Ethan Heilman highlighted that encrypted messaging platforms face immediate risks from quantum threats, specifically through "store-and-forward attacks." Both Signal and Threema are enhancing their security measures; Signal is implementing upgrades like PQXDH and SPQR for post-quantum protection, while Threema is integrating the ML-KEM algorithm for quantum-safe encryption. Research indicated that adapting the Signal protocol for quantum safety may increase bandwidth requirements, necessitating a complete redesign for efficiency.

Bernardo Quintero Uncovers Creator of Virus Málaga and Cybersecurity Legacy | Ukraine news

Bernardo Quintero sought to find the programmer behind the Virus Málaga, which had a significant impact on his life and career in cybersecurity. The virus, initially a piece of malware, sparked Quintero's interest in the field and led to the creation of VirusTotal, which was acquired by Google in 2012. This acquisition helped elevate Málaga as a tech hub in Europe. Quintero revisited the virus code and discovered a clue linking it to a programmer named Enrique, who was affectionately known as Kiki. He learned from Antonio Astorga, a source who passed away, that the virus contained a hidden message against the Basque terrorist group ETA. Astorga's legacy continues through his son, Serhiy, who has aspirations in cybersecurity and quantum computing.

Microsoft teases AI-powered Windows 2030 where keyboards and mice may feel obsolete

David Weston, Microsoft’s Corporate Vice President for Enterprise and OS Security, predicts that by the end of the decade, traditional input devices like keyboards and mice will coexist with more interactive technologies. He envisions AI agents taking over roles traditionally held by security analysts, allowing them to manage tasks such as reading and responding to emails. Microsoft is investing in AI technologies, including the development of Copilot, which aims to enhance productivity. Weston anticipates a shift toward voice and visual inputs for device interaction, moving away from typing and clicking. Microsoft has introduced features like the "Hey Copilot" wake word for voice commands. He also highlights the importance of quantum computing for future security, indicating that quantum-safe encryption is being integrated into Windows. While details about Windows 12 are limited, early indications suggest a deeper integration of Copilot and enhanced security features, potentially transforming Windows into a more intuitive collaborator.
