sslsnoop v0.6 – Dump Live Session Keys From SSH & Decrypt Traffic On The Fly
sslsnoop dumps live session keys from openssh and can also decrypt the traffic on the fly. Works if scapy doesn’t drop packets. using pcap instead of SOCK_RAW helps a lot now. Works better on interactive traffic with no traffic at the time of the ptrace. It follows the flow, after that. Dumps one file by […]
Boffins Crack OpenSSL Library Using Power Fluctuations
[ad] Now this is a very interesting technique, as far as I know I’ve not seen anything similar to this before. It’s like a rather bizarre meld of hardware hacking and software exploitation using cryptographic algorithm cracking techniques. Some rather smart fellas have found a way to extract the private SSL key from a device […]
SSL Renegotiation Bug Succesfully Used To Attack Twitter
[ad] When this SSL Renegotiation bug hit the news, most people said it was a theoretical attack and was of no practical use in the real world. But then people tend to say that about most things don’t they until they get pwned up the face. It turns out the rather obscure SSL flaw can […]
SSL VPNs and OpenVPN – Part IV
4. Brief How-to …. Creating Multiple clients to Single site tunnels. Example of using PKI to create a client-to-site VPN: For a road warrior or roaming/multiple user scenario, static keys based VPNs don’t scale well. You will need to implement a PKI if you have Hub and Spoke architecture of VPN. From the OpenVPN.net website: […]
