Making simple Nmap SPA web GUI with Apache, AngularJS and Python Twisted

Making simple Nmap SPA web GUI with Apache, AngularJS and Python Twisted. The last time I was developing dynamic web applications years ago. I used CGI and PHP back then. 🙂 Now I am really interested in a modern approach, when you have a Single Page Web Application (SPA) written in HTML and JavaScript, that makes http requests to some external API.

It’s pretty cool, because your application becomes API-centric naturally. You work on human interface and improve integration capabilities at the same time. And the task of securing your web app mostly reduces to securing your formalized API.

The very best way to learn something new is to write a post about this stuff. 😉 Here I will reproduce my own steps of making a very basic web app:

  1. Launch Apache web-server with http/https.
  2. Make a simple API service: Nmap wrapper.
  3. Make a web-application with “multipage” experience. There should be at least two pages: Scan and About.
  4. On Scan page it will be possible to input a target (hostname or IP), scan arguments and  launch scan by clicking on the button. The same behavior will be if the target will be passed as a parameter in address bar.
  5. On other pages should be some static text.

As you can see, it is a very limited task, but it should clear up the most confusing parts of the process.

Burp Suite Free Edition and NTLM authentication in ASP.net applications

Burp Suite Free Edition and NTLM authentication in ASP.net applications. As you know, Burp Suit is a scanner for advanced Web Application Security researchers. However, the free version of Burp is more like Firebug analogue, but much more functional.

Let’s see how to install it and use for website analysis. This analysis may be necessary to find vulnerabilities or somehow automate the work with the site. Let’s take, for example, ASP.net applications with NTLM-authorization, which is rather unpleasant to analyze.

Go to the site https://portswigger.net/burp/freedownload and download burp installer as a bash script:

PHDays VII: To Vulnerability Database and beyond

PHDays VII: To Vulnerability Database and beyond. Last Tuesday and Wednesday, May 23-24, I attended PHDays VII conference in Moscow. I was talking there about vulnerability databases and the evolution process of vulnerability assessment tools, as far as I understand it.

To Vulnerability Database and beyond

But first of all, a few words about the conference itself. I can tell that since the last year the event got even better. I’ve seen lot of new faces. Some people I didn’t know, but they knew me by my blog and accounts in social networks. What a strange, strange time we live in! I was very pleased to see and to talk with you all, guys! 🙂

PHDays is one of the few events that truly brings all Russian community of security professionals together. I’ve seen people I have studied with in university, colleagues from the all places where I have been worked, and nearly all researchers and security practitioners that I follow. Big thanks for the organizers, Positive Technologies, for such an amazing opportunity!

It is also a truly international event. You can see speakers from all over the world. And all information is available both in Russian and English. Almost all slides are in English. Three parallel streams of reports, workshops and panel discussions were dubbed by professional simultaneous interpreters, like it is a United Nations sessions or something, recorded and broadcast live by the team of operators and directors. Final result looks really great.

I was talking too fast and used some expressions that was hard to translate. The translator, however, did an awesome job. He is my hero! 🙂 If you didn’t understand something on video, I made a transcript bellow.

A version without translation for Russian-speakers is here.

Today I would like to discuss vulnerability databases and how vulnerability assessment systems has been evolving. Prior to discussing vulnerability databases I need to say that any vulnerability is just a software error, a bug, that allowing hacker to do some cool things. Software developers and vendors post information about such vulnerabilities on their websites. And there are tons and tones of vendors, and websites, and software products, and vulnerabilities.
