Transform your Dir-615 TM into a Wifi Dumper/Cracking Machine

My health is not that good lately, for some reason , I was diagnosed for  asthma  few days ago. 

During Wireless Penetration Testing analysis , i often found that people love to talk about some china/brand wireless card such as SignalKing/Alpha etcx3. While those card might work , it's not portable enough due to the fact you need a PC/Notebook nearby in order to powered up those devices. Which is not good for professional lazy pentester. 

 

So the solution? Turn your antics DIR-615 into a portable wireless monster machine!!!

Disclaimer (If you screw somewhere along the way), well too bad

Steps.1  Flash DIR615 with this firmware ..http://downloads.openwrt.org/attitude_adjustment/12.09/ramips/rt305x/openwrt-ramips-rt305x-dir-615-d-squashfs-factory.bin

To flash you are required to turn off your DIR-615 machine, and hold the reset button for a few seconds, u set your IP to 192.168.0.x>1 , go to 192.168.0.1 and you will be redirected to the firmware upgrade page.

Upload the firmware.

Step2. 

• Download the sysupgrade firmware http://downloads.openwrt.org/attitude_adjustment/12.09/ramips/rt305x/openwrt-ramips-rt305x-dir-620-a1-squashfs-sysupgrade.bin 
• Setup openwrt initially
• Push sysupgrade into openwrt via scp to /tmp
• ssh into your openwrt and use the sysupgrade  -v openwrt-ramips-rt305x-dir-620-a1-squashfs-sysupgrade.bin

Step 3

• If you have luci you can set the wifi into Monitor mode via Luci HTTP.
  
• or modified /etc/config/wireless to be something like this
  

• Tips your openwrt should`t have Internet connection, opkg relies on wget which respect http_proxy env,, I used polipo proxy so to make opkg works i usually use ssh root@192.168.1.1 -R8123:localhost:8123 

After that install  opkg install aircrack-ng kmod-usb-storage kmod-fs-vfat wireless-tools screen . Try not to install too much stuff since space is very limited.

And that's it. use screen to deamonized your stuff.

Knowledge about dumping to your usb drive and airocrack usage is left for your own exercise..
