Two weeks ago, SharifCTF was hold and the questions were acceptable. We attended with CGU team name and and gain the 44th place among the 682 attended teams, whom has at least one question solved in the CTF.

Offsec is an Iranian computer security group which holds conferences or CTFs in the computer security area. In their recent challenge, they created a web challenge which is accessible through their Telegram channel. The challenge started on 16 Dec 2016 and here I will WRITE UP! 🙂

Knowing all possible web paths in the world is the initial step for making a search engine (SE). By means of SE one can analyze the web for the material he/she likes. In normal Domain Name System, each TLD provider (Top Level Domain) can sell or release list of all its domains. As an example .com TLD can sell or release all the domains which are end with “.com“. But the problem is more complicated in TOR (or other hidden service providers). In this post I will talk about my tool named Onion Harvester and how to find initial points for finding hidden services to be crawled.
In another post, I have described how to configure GPG (PGP) + Enigmail + Thunderbird for sending signed and encrypted emails. But the inner process of PGP is not described. In this post, I will describe how PGP works and the emulation process of PGP will be covered by the nice cryptography tool named cryptoolv2.
In the previous post, the configuration steps for controlling the home IoT system remotely, are described. In this post I will describe how to control your system graphically!
By means of IoT lots of things can be connected and controlled by Internet such as smart homes. In this small tutorial I will discuss about personal smart home solutions and how to remotely control them. In small word “Control your Home IoT System over TOR” 🙂
But they have restriction for seeing results. For example SHODAN lets for unregistered users to view just 1 page (10 results). If you registered, the limitation is 5 pages. But again restriction!
So what to do?
