Researchers Crack 4096-bit RSA Encryption With a Microphone

So this is a pretty interesting acoustic based cryptanalysis side-channel attack which can crack 4096-bit RSA encryption. It’s been a while since we’ve seen anything hardware based, and RSA 4096 is pretty strong encryption, I wonder how they figured this one out. It makes sense though when you think about it, although I wouldn’t have [...]

Similar somewhat to the recent breaking of OpenSSL using power fluctuations. This time some researcher type fellas focused on the digital noise autocomplete webforms [...]

You have to pay up to get the ‘decryptor’ and get access to your files again. This is pretty dangerous…and cunning too. It’s not easily broken either, they are using RSA 1024-bit [...]

SHA-1 Cracked – Old News, But People Still Talk

A paper about cracking SHA-1 originally surfaced in 2005, from a fairly reputable scientific source in China, it was widely publicised nor talked about much. But then recently, just last month China managed to make a wave out of it, almost 2 years after the initial ‘report’. It was even Slashdotted on January 20th 2007, [...]
