In “Encrypting Emails using PGP/GPG”, 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 “Control your home IoT”, 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” 🙂
You may have visit SHODAN (The IoT search engine) or ZoomEye (World Wide Port Search Engine). The systems are very useful to have a good view of world! 🙂
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?
In this tutorial I want to write about using Apache Spark on Ubuntu machines where you can develop big data analysis apps with it.
First of all, I want to write a small and quick introduction to Hadoop + Spark environment. Hadoop makes it possible to work with lots of computers in a cluster. Work can be: storing files in cluster (HDFS – Hadoop Distributed File System), storing database in cluster (Apache HBase), or run software in cluster (MapReduce, Spark).
I’ve met 2048 game many years ago. It is an addictive game witch takes lots of time from the player. 🙁
So what should I do if I want to have high score and save time? Here is where Smali takes part. 🙂
In this post I will describe how to inject into Android 2048 game and change the score! Continue reading Smali Code Injection: Playing with 2048!
PGP (Pretty Good Privacy) is a protocol for encryption and authentication of files and emails. In this tutorial I want to show how to create encrypted and signed emails using GPG (GnuPG), Thunderbird (Email Client), and Enigmail (Connector). I used windows as test case which the steps are same for *nix systems. Continue reading Encrypting Emails using PGP/GPG
In the next weeks, two sessions about web application vulnerabilities and Android Analysis and Code Injection will be held at Urmia University CERT.

In this post I wanted to demonstrate a simple code injection example in Android. As indicated in previous posts about reversing java, the method of code execution is same in Android. Whereas Java, the BYTE CODE are SMALI codes here and the executor is Dalvik (recently ART) in Android (not JVM). Here in this post, I will describe shortly how to reverse and inject code in SMALI.
