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 ' ...

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 ...

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 ...

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 ...

A research paper presented at the Usenix security conference last week detailed a new technique for retrieving encryption keys from electronic devices, a method that is much faster than all previously ...

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 ...

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 ...
