Friday deployments (…and leaving afterwards)
Do not feed RSA private key information to the random subsystem as entropy. It might be fed to a pluggable random subsystem…. What were they thinking?!
Ladies and gentlemen, start coding.
Brian Kernighan, the first person who documented the use of the epic words “Hello, world” in a computer language, declares the first ever Coding World Championship open. Thank you, Brian!
The race is on. We wish you the best of luck in the competition!
Privilege escalation, lateral movements and hash dumps. How to prevent a lot of attacks by smart cards and disabling NTLM.
Yet another manifestation of jw.fi.
My previous posts are archived as html on my hard drive as I had to make a semi-emergency evacuation of my previous host since TextDrive is finally pulling the plug.
The attack can extract full 4096-bit RSA decryption keys from laptop computers (of various models), within an hour, using the sound generated by the computer during the decryption of some chosen ciphertexts. We experimentally demonstrate that such attacks can be carried out, using either a plain mobile phone placed next to the computer, or a more sensitive microphone placed 4 meters away.
