Intel Ping Of Death!!

Do you remember the old Ping Of Death attack?? How cool was it ?! At that time breaking the stack was as simple as breaking the modelling assumptions, for example breaking the stack in 1997 was as simple as sending to the target stack a unexpected length in the ICMP packet ! The time being where a malformed source and destination address caused the smurf attack. After those implementation mistakes, developers, engineers and the developing frameworks became more and more sophisticated, became more and more complete in term of security checking. It is a long time since I saw another mistake like this ! ... Until today ! Today I've read a post talking about another implementation bug in the TCP/IP stack made by Intel engineers. The writer shows how the Intel card ( 82574L ) shouts down if a specific value (0x32) is placed into a specific address ( 0x47F). Which basically means if the ASCII "2" is into a specific address in the sent stream. Let's take a closer look to the byte stream:

Shutting down an ethernet card could be pretty annoying for a system, in fact you need to reboot your entire machine before getting the card working back again. Further analysis showed that different values placed into the same address, change the card behavior. So hard to find so easy to test.

Install Virtual Box On Kali Rolling

If you facing problem with virtualbox installation on kali rolling edition because of its outdated kernel 4.3.0-kali1-amd64 then this post is for you only.

Step1: Install latest kernel. First search the cache for list of available ones apt-cache search linux-headers
Depending upon the list choose one from the set and install install it.
you can download kernel file using wget from ubuntu source also.
example:wget kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.3-wily/linux-image-4.4.3-040403-generic_4.4.3-040403.201602251634_amd64.deb
for more refer to this post: link

Step2:
Edit the boot entry /boot/vmlinuz-(New Linux kernel Version) & /boot/initrd.img-(New Linux kernel version) in grub menu.

Before making boot entry changes be sure these files exist in the /boot directory after running install command.
In my case following new file got created in /boot folder:

1)vmlinuz-4.6.0-kali1-amd64
2)initrd.img-4.6.0-kali1-amd64

Thats all you need to do to install any virtual software on kali r…

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…
