The WiFi Pineapple, was a device coined by the Hak5 (www.hak5.org) Team back in 2008. Originally it was a hacked Fon/Fonera AccessPoint (AP) with Karma patches applied to hostapd. Back then Digninja (Robin wood) called it Jasager (http://www.digininja.org/jasager/), it was called this because the AP software answered “Yes” to all WiFi Beacon Frames; if a WiFi client was looking for the SSID BTOpenzone the Pineapple(or Jasager) would reply “That’s Me!”, if a second WiFi client was looking for an SSID of Starbucks, again the Pineapple would reply “Thats Me!” – Thus tricking unsuspecting users/devices into associating with its private network. From this stage you could attack WiFi clients, and perfrom Man-in-The-Middle(MiTM) attacks on their interenet traffic!.
As the device was small, it was a running joke to hide it within an actual pineapple. Then the Hak5 Team discovered some novelty pineapple cocktail-cups which could house the AP board and a small battery pack (Hence the name Pineapple). Nowadays, its a chunky black Alfa AP121U with a nice sticker of an armed pineapple that looks a bit like a viking, slapped on its front cover.
The original Fon device only had a finite amount of processing power and memory, and attacks were limited, any extensive process and the watchdog process would trigger and reset the device (assuming a DoS condition was occurring). The Hak5 development Team moved onto other devices as sourcing Fon/Foneras became difficult, and eventually onto slightly more powerful APs; which brings us to the current module Mk IV. The community has since added they’re own modules, improved the interface and added extra functionality like 3G tethering and 3G USB Modem support.
Blue for the Pineapple…
So back to the main topic. We missed the small unobtrusive AP, so conducted some research on porting the Pineapple build onto a cheap small TPLink WiFi AP that costs approximately $20USD.
Our walkthrough is below, but here is the part list:
- TPLink WR703N – $20(USD)
- 4GB San Cruiser FIT USB Drive – $8(USD)
As the parts are from China/Thailand they can be cheaply acquired anywhere in the world!
This blog post is centered around version 1.5 of the TPLink WR703N. People are reporting recieving different versions upto v1.7. For version 1.6, the image below seems to corrupt or brick the device, general consensus from the comments are to use the later 12.09-rc2. Version 1.7 Attitutude adjustment is confirmed as working, however the trunk is broken… so watch this space…
The default web interface language is all in Chinese, so follow these simple instructions to flash a copy of OpenWRT (http://openwrt.org/)
- Configure your computer with a static IP address of 192.168.1.111
- Connect your computer to the TPLink with an ethernet cable and power on the TPLink through a USB cable (or USB battery)
- Browse to 192.168.1.1. Login admin:admin.
- Mouseover the left hand links to find the DateTimeCfgRpm.htm link and click
- Mouseover the expanded menu to find SoftwareUpgradeRpm.htm link and click
- Use the dialog to upload the new flash (link below) to the TPLink. It will go through a 100% status bar twice then reboot.
Openwrt attitude adjustment on squashfs root can mount an external drive as root with overlayfs.
I used the following Firmware for Version 1.5 (found on the back next to the Serial Number):
For version 1.6, the image above seems to corrupt or brick the device, general consensus from the comments are to use the later 12.09-rc2.
For version 1.7….. TBA
Preparing The USB as / (root)
Format a usb key with two partitions, ext4 and swap, install attitude adjustment squashfs, connect it to the internet (wifi client/eth0), update package lists.
Copy necessary files from flash to the new root partition:
For pivot overlay you can either use an empty new rootfs OR copy the contents of the current overlay (JFFS2) to the new rootfs (assuming the filesystem for the new external rootfs is mounted on /mnt/sda2 (swap=/dev/sda1)):
tar -C /overlay -cvf - . | tar -C /mnt/sda2 -xf -
For pivot root (”only possible as of r26109!”) you must make sure to have a complete root filesystem on the external rootfs device. One possible way to get such a system (assuming the filesystem for the new external rootfs is mounted on /mnt/sda1) is to issue
mkdir -p /tmp/cproot mount --bind / /tmp/cproot tar -C /tmp/cproot -cvf - . | tar -C /mnt/sda2 -xf - sync ; umount /mnt umount /tmp/cproot
Whole external root (pivot root)
After r26109 you can configure a non-overlay rootfs (called a whole_root extroot because the entire filesystem must be present on device, not only the changes from the SquashFS) using option target / in the config mount section for the rootfs device.
In order to set up such a whole root overlay, refer to the example below.
option is_rootfs will still work after r25787, the preferred method of configuring the extroot is
option target /overlay in the
config mount section for the rootfs device in the
config mount option target / option device /dev/sda2 option fstype ext4 option options rw,sync option enabled 1 option enabled_fsck 0
Reboot & Install Packages
You can now install whatever you want from opkg, and it all goes on the USB Drive.
For some Wifi Cracking, here’s a bunch of useful package names:
opkg install htop bash nano netcat tar openssh-sftp-client nmap tcpdump aircrack-ng kismet-client kismet-server nbtscan snort karma samba36-client elinks yafc python php5-cgi uhttpd zoneinfo-core procps
At this point you can install any additional packages you may want/need!
Installing the Hak5 Pineapple Code
The following series of instructions were performed from both a Linux and Mac OSX operating system.
Hacking the Upgrade Image
We used binwalk (https://code.google.com/p/binwalk/) to extract information about the FileSystem boundaries contained within the Hak5 Pineapples upgrade binary firmware image upgrade.bin which is obtainable from http://www.wifipineapple.com/ Direct Link to Image:Firmware-2.8.0
Below is the output of binary-walking the image file:
$ binwalk upgrade.bin DECIMAL HEX DESCRIPTION ------------------------------------------------------------------------------------------------------- 0 0x0 Squashfs filesystem, little endian, version 4.0, compression: size: 5342622 bytes, 1410 inodes, blocksize: 262144 bytes, created: Thu Jul 12 02:09:55 2012 6291456 0x600000 uImage header, header size: 64 bytes, header CRC: 0x6B09056F, created: Thu Jul 12 02:10:00 2012, image size: 890595 bytes, Data Address: 0x80060000, Entry Point: 0x80060000, data CRC: 0xF9DC8F7E, OS: Linux, CPU: MIPS, image type: OS Kernel Image, compression type: lzma, image name: MIPS OpenWrt Linux-3.2.14 6291520 0x600040 LZMA compressed data (sig 3), properties: 0x6D, dictionary size: 8388608 bytes, uncompressed size: 2690180 bytes
Use dd to extract the image:
Next we use the native unix tool dd, to carve out the squashFS partition:
$dd if=upgrade.bin of=pineapple.img bs=1 count=5342622 5342622+0 records in 5342622+0 records out 5342622 bytes transferred in 12.967170 secs (412011 bytes/sec)
Linux and Mac OSX have a neat program called FUSE (Filesystem in UserSpacE), which allows users to mount/edit filesystems outside of standard kernel code.
Using Squashfuse(https://github.com/vasi/squashfuse) it is incredibly easy to mount the pineapple.img, we extracted earlier. This part of the walkthrough was conducted on OSX (but can easily be replicated in Linux):
mkdir -p /Volumnes/pineapple squashfuse pineapple.img /Volumes/pineapple/
Extract the (MIPS) karma patched binaries (to save on compliation, and from having to build & patch our own binaries)
$ find /Volumes/pineapple/ -name hostapd /Volumes/pineapple//lib/wifi/hostapd.sh /Volumes/pineapple//usr/sbin/hostapd $ find /Volumes/pineapple/ -name hostapd_cli /Volumes/pineapple//usr/sbin/hostapd_cli
The copy/ssh these binaries onto the TPLink Openwrt installation.
The Pineapples Web Interface
If you followed the firmware & squashFS extraction you may continue with the following steps, or skip to the next New Opensource section….
This stage involves copying all the PHP code for the Pineapples Web interface; earlier versions were stored at /www/pineapple later versions not store the code within the images’ root /pineappple
New Opensource Method
As of the last month Sebkinne, has made the Pineapples Web Interface available as Opensource, use git to download the repository.
git clone https://github.com/WiFiPineapple/web-interface.git /pineapple
- Disable all update modules – as this will break the build, the upgrades/updates are all geared for Alfa AccessPoints so you should go through all the code removing the update/upgrade routines to avoid accidentally bricking the TPLink in the future.
- Simple disable method: remove the ‘upgrade’ folder within the ‘/pineapple’ folder.
To make this build compatible with the existing Pineapple Scripts (eg. http://wifipineapple.com/wp4.sh). You need to replace the exisitng Openwrt configurations with the ones listed below.
