A research paper that claimed a quantum breakthrough that could "challenge RSA-2048" encryption received significant attention in the past week, followed by significant criticism as experts weighed in ...

DEF CON 33, the world's largest security event held in Las Vegas in August 2025, Konstantinos Karagiannis, a leading expert in quantum computing and cybersecurity, gave a presentation titled ' ...

Security researchers have successfully broken one of the most secure encryption algorithms, 4096-bit RSA, by listening -- yes, with a microphone-- to a computer as it decrypts some encrypted data. The ...

Encryption algorithms can be intimidating to approach, what’s with all the math involved. However, once you start digging into them, you can break the math apart into smaller steps, and get a feel of ...

In short, ransomware uses an assortment of techniques to block access to the victim’s system or files, usually requiring payment of a ransom to regain access. Recently we have seen significantly ...

The process — carried out in early December — generated a five-terabyte decryption table and, say the researchers, would have taken them around 1,500 years using an AMD Opteron-based single PC. The ...

Cryptography is the practice and study of techniques for secure communication in the presence of third parties (called adversaries). More generally, it is about constructing and analyzing protocols ...

More than 11 million websites and e-mail services protected by the transport layer security protocol are vulnerable to a newly discovered, low-cost attack that decrypts sensitive communications in a ...
