Disable SSLv3 & TLS1.0 Windows Server 2012 R2
A video about disabling SSL v3.0 and TLS v1.0 on Windows Server 2012 R2 in Registry Editor. I've created a step by step guide on disabling SSLv3 and TLS v1.0 here - https://www.phr33fall.co.uk/ssl-tls-issues-server-2012/ If you're looking to remove support for RC4, TripleDES and Diffie-Hellman, you can find that here - https://youtu.be/8eoU0gVvzpE Or the step by step guide to disable weaker ciphers is here - https://www.phr33fall.co.uk/weakciphers/

Recover a RSA Private Key From a TLS Session With Perfect Forward Secrecy
by Marco Ortisi They always taught us that the only thing that can be pulled out from a SSL/TLS session using strong authentication and latest Perferct Forward Secrecy ciphersuites is the public key of the certificate exchanged during the handshake - an insufficient condition to place a MiTM attack without to generate alarms on the validity of the TLS connection and certificate itself. Anyway, this is not always true. In certain circumstances it is possible to derive the private key of server regardless of the size of the used modulus. Even RSA keys of 4096 bits can be factored at the cost of a few CPU cycles and computational resources. All that needed is the generation of a faulty digital signature from server, an event that can be observed when occurring certain conditions such as CPU overheating, RAM errors or other hardware faults. Because of these premises, devices like firewall, switch, router and other embedded appliances are more exposed than traditional IT servers or clients. During the talk, the author will explain the theory behind the attack, how common the factors are that make it possible and his custom pratical implementation of the technique. At the end, a proof-of-concept, able to work both in passive mode (i.e. only by sniffing the network traffic) and in active mode (namely, by participating directly in the establishment of TLS handshakes), will be released.

Backdoor Diffie-Hellman
Just a demo of how the backdoor works. The client connects with TLS to the server through a proxy (easy way to emulate a MITM). The proxy detects the backdoored DH parameters, compute the shared key, decrypt the traffic. All that was changed is two public value, hopping to cut it down to only one soon.

openvpn kullanımı  linux ip gizleme görünmez ol
linux işletim sisteminde openvpn yani vpnbook kullanımından bahsetttik tor proxy ye alternatiftir ipnizi gizlersiniz görünmez olursunuz. OpenVPN is an open-source software application that implements virtual private network (VPN) techniques for creating secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. It uses a custom security protocol[9] that utilizes SSL/TLS for key exchange. It is capable of traversing network address translators (NATs) and firewalls. It was written by James Yonan and is published under the GNU General Public License (GPL).[10] OpenVPN allows peers to authenticate each other using a pre-shared secret key, certificates or username/password. When used in a multiclient-server configuration, it allows the server to release an authentication certificate for every client, using signature and Certificate authority. It uses the OpenSSL encryption library extensively, as well as the SSLv3/TLSv1 protocol, and contains many security and control features. OpenVPN has been ported and embedded to several systems. For example, DD-WRT has the OpenVPN server function. SoftEther VPN, a multi-protocol VPN server, has an implementation of OpenVPN protocol.

MitM Attack by Name Collision: Cause Analysis and Vulnerability Assessment in the New gTLD Era
MitM Attack by Name Collision: Cause Analysis and Vulnerability Assessment in the New gTLD Era Qi Alfred Chen (University of Michigan) Presented at the 2016 IEEE Symposium on Security & Privacy May 23–25, 2016 San Jose, CA http://www.ieee-security.org/TC/SP2016/ ABSTRACT Recently, Man in the Middle (MitM) attacks on web browsing have become easier than they have ever been before because of a problem called "Name Collision" and a protocol called the Web Proxy Auto-Discovery (WPAD) protocol. This name collision attack can cause all web traffic of an Internet user to be redirected to a MitM proxy automatically right after the launching of a standard browser. The underlying problem of this attack is internal namespace WPAD query leakage, which itself is a known problem for years. However, it remains understudied since it was not easily exploitable before the recent new gTLD (generic Top-Level Domains) delegation. In this paper, we focus on this newly-exposed MitM attack vector and perform the first systematic study of the underlying problem causes and its vulnerability status in the wild. First, we show the severity of the problem by characterizing leaked WPAD query traffic to the DNS root servers, and find that a major cause of the leakage problem is actually a result of settings on the end user devices. More specifically, we find that under common settings, devices can mistakenly generate internal queries when used outside an internal network (e.g., used at home). Second, we define and quantify a candidate measure of attack surface by defining "highly-vulnerable domains", which are domains routinely exposing a large number of potential victims, and use it to perform a systematic assessment of the vulnerability status. We find that almost all leaked queries are for new gTLD domains we define to be highly-vulnerable, indirectly validating our attack surface definition. We further find that 10% of these highly-vulnerable domains have already been registered, making the corresponding users immediately vulnerable to the exploit at any time. Our results provide a strong and urgent message to deploy proactive protection. We discuss promising directions for remediation at the new gTLD registry, Autonomous System (AS), and end user levels, and use empirical data analysis to estimate and compare their effectiveness and deployment difficulties.

Stop using SSL3, Force TLS settings
Protect yourself from the so called "POODLE" bug. Really by now we should be enforcing newer protocols TLS1.2 and 1.1. A number of websites/servers still only support TLS1.0 so it's acceptable to use this as a minimum so as not to interrupt your browsing. Try using just tls1.2 and see what interruptions you get. That will identify what servers are not using the latest cipher list.

Were It So Easy: TLS in the Real World - Duo Tech Talk
Between Logjam, FREAK, POODLE, and Heartbleed, TLS hasn't had a good year. TLS is the most commonly deployed cryptographic protocol, but is notoriously difficult to both implement and deploy, resulting in widespread security issues for many of the top services on the Internet. For the past three years, we've been working to improve the global state of TLS deployment through measurement-based approaches, including tracking the impact of Heartbleed and other vulnerabilities. Based on measurement data, we conducted one of the largest-ever mass vulnerability notification campaigns, discovered failures in how Diffie-Hellman has been deployed in practice, and uncovered the Logjam attack against TLS. In this talk, we'll briefly examine what TLS is and how it fails, and present the Logjam attack. We'll also discuss ZMap, the Internet-wide network scanner we use for our research, and show how ZMap helped lead to the discovery of Logjam.
