Divide and Conquer: Cracking MS-CHAPv2 with a 100% success rate. Divide and Conquer: Cracking MS-CHAPv2 with a 100% success rateJul 29, 2012 At Defcon 20 last weekend, David Hulton and I gave a presentation on cracking MS-CHAPv2.

Divide and Conquer: Cracking MS-CHAPv2 with a 100% success rate

This blog post is meant to be a rough overview of what we covered in our talk. Why MS-CHAPv2? The first obvious question is why we looked at MS-CHAPv2, given a lingering sense that the internet should already know better than to rely on it. Unfortunately, however, even as an aging protocol with some prevalent criticism, it's still used quite pervasively. We believe that MS-CHAPv2 remains so prevalent because previous examinations of the protocol's potential weaknesses have focused mostly on dictionary attacks.

In their 1999 analysis of the protocol, for instance, Bruce Schneier and Mudge conclude "Microsoft has improved PPTP to correct the major security weaknesses described in [SM98]. HTML Templates.

If you would rather use a commercial product tailored for your specific operating system, please consider John the Ripper Pro, which is distributed primarily in the form of "native" packages for the target operating systems and in general is meant to be easier to install and use while delivering optimal performance. This version integrates lots of contributed patches adding GPU support (OpenCL and CUDA), support for a hundred of additional hash and cipher types (including popular ones such as NTLM, raw MD5, etc., and even things such as encrypted OpenSSH private keys, ZIP and RAR archives, PDF files, etc.), as well as some optimizations and features. Unfortunately, its overall quality is lower than the official version's. Requires OpenSSL. Penetration Testing Tools and How2s. Talend Data Preparation for Analytics: Self-Service Data Prep Tools.

Weka – Graphical User Interference Way To Learn Machine Learning

Weka has been around for quite a while and was developed internally at University of Waikato for research purpose. What makes Weka worthy of try is the easy learning curve. For someone who hasn’t coded for a while, Weka with its GUI provides easiest transition into the world of Data Science. Being written in Java, those with Java experience can call the library into their code as well. Personally, I had my first shot at Data Science when I took a course at University of Waikato. Below is the pedagogy of stepwise learning which will help you to understand the concepts in a better & concrete manner: Step 1 : What is Weka and Why to use it? According to Wikipedia:, Weka is a collection of machine learning algorithms for data mining tasks. You might want to have a look at this video from Brandon Weinberg.

18 Free Exploratory Data Analysis Tools For People who don't code so well

All of us are born with special talents. It’s just a matter of time until we discover it and start believing in ourselves. We all have limitations, but should we stop there? No. When I started coding in R, I struggled. Now when I look back, I laugh at myself. Data exploration is an inevitable part of predictive modeling. I have written this article to help you acknowledge various free tools available for exploratory data analysis.

Top 50 Hacking Tools That You Must Have

While these tools do make working simpler but cannot compensate for the vast amount of knowledge required in this field. In this post i’m going to mention 50 different tools under 9 categories that your ‘Hack Lab’ must have. Most of the tools mentioned in this post are pre-included in Kali Linux which you can install to have them at once. Intrusion Detection Systems :- These are the tools you must have if you’re building a hack lab for penetration testing or for any security arrangement. SnortNetCop Encryption Tools :- While the above tools do identify any suspicious activity but they can’t protect your data, you need encryption tools for that.
