We at null Delhi had many participants (especially the new comers in the field of hacking and security) ask basic questions about CTFs like what is CTF? How to participate in CTF contests? What kind of skills are required? so and so forth since the time of nullcon V earlier this year. While we were answering those questions we found a need of a real time challenge which we can put in front of attendees and they can probably play around with it to find the answers themselves. During this course we decided to put different challenges in front of the attendees related to various domains of security (reverse engineering, web application hacking, cryptography, forensics, operating systems, etc.) and ask them to solve these challenges at the venue itself. They can take assistance from the mods and their neighbors or do it themselves. After every challenge we would cover a detailed walkthrough which would not only focus on the solution of the particular challenge but would also clarify the concepts of techniques to be used during CTFs.
We had our 1st ever null Dharamshala meet on the 29th of March 2014. There were around 25 participants who attended. Their professions ranged from IT professional, web developer to freelancers. The view from the venue was breathtaking. One could see the whole of Dharamshala from there.

I had a fabulous experience at “Wireless Hacking with Kali” Null Humla session. When the humla session was announced, the subject sounded very interesting.

I finished my work at 5:00 AM in the morning as usual and unfortunately was not feeling sleepy so what next? Yes! It’s the Ahaa Moment of the Day – Why not pen down the spirit that keeps us ticking! I decided to write about the spirit of null that keeps us ticking and keeps it running faster every day.
Puliya means culvert or a small bridge in Hindi.
We have been getting constant feedback about our null Humla and null Bachaav sessions. The feedback is both ways and almost all the champions are of the opinion that there are some essential non-security skills that are sorely lacking in a lot of attendees.
Bachaav (meaning defence in Hindi) is a completely hands-on workshop with the clear focus on learning the tools, techniques and approaches of defensive security using simulated servers and networks.
Bachaav is different from a normal null meet in its focus and duration. The focus is on learning specific tools and techniques and the duration is about 5-6 hours of hands-on work.
This is a personal account of Sudhir Babu who attended the null Bangalore Browser Fuzzing Humla session taken by null Humla champion Anil Aphale.
I had an amazing experience last Saturday at Null Humla “Browser Fuzzing” session. “Browser Fuzzing”?? It was an alien concept for me, I did some work with Java script previously but I never understood why my browser ever crashed; most of the times I just ignored it

Delhi – The Second Adventure
Joerg Simon was back in Delhi on 27th July (Saturday) which he named his second adventure after a gap of 10 months. The last time he was in Delhi was for NullCon Delhi, 2012 with his talk on Fedora Security lab, OSSTMM. He could not complete his talk last time because he messed up his own time. It was a wonderful opportunity for everyone to meet to meet him personally and share and learn things about Open Source Security.
