Install And Configure Yara


Step1:To Install YARA on Ubuntu we need the PCRE and some libraries first:
  sudo apt-get install libpcre3 libpcre3-dev 
Then we start downloading the YARA source code:
$ wget http://yara-project.googlecode.com/files/yara-1.4.tar.gz 
$ wget http://yara-project.googlecode.com/files/yara-python-1.4.tar.gz

Step2: Compile and install yara on your linux box.
 a) cd yara-1.4
    chmod +x -R /root/Desktop/yara-1.4/*
   ./configure
    make
    make check
    make install

  b)cd ..
    cd yara-python-1.4
    python setup.py install



Step 3: Convert clamav database to yara
http://code.google.com/p/malwarecookbook/source/browse/trunk/3/3/clamav_to_yara.py?r=5

sigtool -u /var/lib/clamav/main.cvd                                     //decompress the database
python clamav_to_yara.py -f main.ndb -o clamav.yara    //convert clamav to yara

Step 4:For packing signature(PEID tool uses these signature to detect type of packing) go to this site and copy packer signatures in a file .Now with the help of this file we can detect packed malware using  yara.
yara -r packersrule infected-file

Hacking Windows 10 UWP App: DLL Injection & common Vulnerabilities

I recently started working on  widows 10 Apps( Apps not Applications) security. Before diving deep in hacking terms lets try to understand what's new in Windows 10 UWP( Universal Platform) as compared to old Apps. Lets begin with how apps actually work on windows 10(desktop/tablet). Now windows 10 comes with a container only for running apps inside the isolated environment. By default, /APPCONTAINER(Linker Flag) is off. This option modifies an executable to indicate whether the app must be run in the appcontainer process-isolation environment. Specify /APPCONTAINER for an app that must run in the appcontainer environment—for example, a Windows Store app. (The option is set automatically in Visual Studio when you create a Windows Store app from a template.) For a desktop app, specify /APPCONTAINER:NO or just omit the option. The /APPCONTAINER option was introduced in Windows 8. Now there is no registry entry concept for these app in the System HIVE rather they install they own hiv

SSI Injection Attack

SSIs are directives present on Web applications used to feed an HTML page with dynamic contents. They are similar to CGIs, except that SSIs are used to execute some actions before the current page is loaded or while the page is being visualized. In order to do so, the web server analyzes SSI before supplying the page to the user. The Server-Side Includes attack allows the exploitation of a web application by injecting scripts in HTML pages or executing arbitrary codes remotely. It can be exploited through manipulation of SSI in use in the application or force its use through user input fields. It is possible to check if the application is properly validating input fields data by inserting characters that are used in SSI directives, like:  Code: < ! # = / . " - > and [a-zA-Z0-9] Another way to discover if the application is vulnerable is to verify the presence of pages with extension .stm, .shtm and .shtml. However, the lack of these type of pages does not mean that th
