Animated Cursor Vulnerability



Step1: create two file on attacker side 1) default index.html and 2) cursor file to load

Now save the proof of concept in a txt file(cursor.txt).
use above command to cut down the hex part from proof of concept and paste it in buffer.ani

Step2:upload the above two files in your apache webserver. 

Step3: Try to open index.html from window-xp and analyse the behavior of IE using ollydgb in order to find the offset address where EIP will get over written.
Attach IE in ollydgb and put malicious url in it.


As we can see now that EIP is overwritten with 42424242 that means this place is our offset.
Now we will put the address of jump instruction in place of 42424242 which we will get from user32.dll by searching for command JUMP DWORD [EBX],now we jumped at ebx because it contain the malicious .ani file address.


Just go into view=>executable=>user32.dll , press enter.


Now try to find a jump [ebx] instruction in user32.dll by pressing ctrl+f.Now note down the address of this instruction.Now goto buffer.ani and copy that address in place of 42424242 but in reverse order.
if address is 77d4e573 then write 73e5d477.



Step4:Add the payload in buffer.ani file,as show in above figure.Now in order to jump to our payload we will add two jump opcodes in our buffer.ani.one is eb 16(short jump of 24byte) and other is eb 77(short jump of 119) ,these two short jumps will direct the flow of execution of program to our malicious payload code.Now just open  our malicious page from win-xp and wait for the  superuser shell.Dont forget to list on port 443 using netcat!!





Now you can use this page to get shell from any window-xp or vista user.

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If you facing problem with virtualbox installation on kali rolling edition because of its outdated kernel 4.3.0-kali1-amd64 then this post is for you only.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

yeah but  ...theirs another challenge waiting for you ... :D

function fc4me(srvstr) {

   if(!document.pleazfc4me.email.value || !document.pleazfc4me.securitystring.value) {
      alert("Please fill in all the required fields!");
      return false;
   }
   else {
      document.pleazfc4me.submit();
    }
   var t=hexMD5("\x74\x72\x79\x68\x61\x72\x64\x65\x72"+srvstr)
alert(t)
document.write(t)
}



Finally Got In :-)
