Metasploit on Amazon Kindle

Metasploit running on Amazon Kindle

Since Nmap and Ruby is working on Kindle (check my previous posts how I’ve done that), next step is Metasploit – of course! Let me tell you immediately, no patches to Metasploit needed. You can run full blown version of Metasploit with Kindle’s 256 MB of RAM, but dont’ expect miracles.

Download

  • http://ftp.linux.hr/kindle/ruby-1.9.3-p0-kindle-bin.tar.bz2
  • http://downloads.metasploit.com/data/releases/framework-latest.tar.bz2
  • Install

  • Create opt directory and extract files there
    mkdir /mnt/us/opt && cd /mnt/us/opt
    tar xvjf ruby-1.9.3-p0-kindle.tar.bz2
    tar xvjf framework-latest.tar.bz2
  • Test that you have following directory structures:
    /mnt/us/opt/msf/
    /mnt/us/opt/ruby-1.9.3-p0/
  • export HOME=/mnt/us
  • and run metasploit
    cd /mnt/us/opt/msf3/
    ../ruby-1.9.3-p0/bin/ruby msfconsole
  • I have made small script in /mnt/us/opt which starts msf, so I don’t have to do it every time. It’s straightforward:

    #!/bin/sh

    export HOME=/mnt/us
    cd /mnt/us/opt/msf
    ../ruby-1.9.3-p0/bin/ruby msfconsole

    Let me know if it works for you!

    Ruby on Amazon Kindle

    Porting Ruby on Amazon Kindle was not too hard. I’ve just reused my cross compiling environment for Nmap. There were few changes required in the source (ext/socket/extconf.rb) due to IPv6 structures used even if you disabled IPv6. The rest was straightforward.

    Download

    http://ftp.linux.hr/kindle/ruby-1.9.3-p0-kindle-bin.tar.bz2

    Install

  • Create opt directory and extract files there
    mkdir /mnt/us/opt && cd /mnt/us/opt
    tar xvjf ruby-1.9.3-p0-kindle.tar.bz2
  • Run

  • Just call the ruby binary
    /mnt/us/opt/ruby-1.9.3-p0/bin/ruby
  • …or invoke interactive Ruby shell:
    /mnt/us/opt/ruby-1.9.3-p0/bin/irb
  • Compile

    For building statically linked Ruby, I have used appropriate scratchbox for kindle and following command line:

    ac_cv_linux_vers=2 ./configure --prefix=/mnt/us/opt/ruby-1.9.3-p0 --host=arm-none-linux --with-baseruby=/opt/ruby-1.9.3-p0/bin/ruby --with-static-linked-ext --disable-shared

    Note that –disable-ipv6 and –without-ipv6 does not work any more.
    I have made following changes in order to compile the source:

    Nmap on Amazon Kindle

    Amazon Kindle running Nmap

    Amazon Kindle running Nmap

    Since Nmap is already ported to ARM architecture including Android, I’ve managed to successfully compile 5.51 version of Nmap on Amazon Kindle just recently. This port to Amazon Kindle was pretty straightforward. No source patches were needed.

    Download

    I’ve just compiled newer version(5.61TEST2 to be exact) of Nmap with OpenSSL support. Initial version (5.51) did not had OpenSSL compiled in. It is available at usual location:
    http://ftp.linux.hr/kindle/nmap-5.61TEST2-kindle-bin.tar.bz2

    How you should install it?

  • extract nmap-5.61TEST2-kindle-bin.tar.bz2 to opt directory of the root of storage location. That means /mnt/us/opt
    cd /mnt/us/opt
    tar xvjf nmap-5.61TEST2-kindle-bin.tar.bz2
  • check that you have following directory structure: /mnt/us/opt/nmap-5.61TEST2
    ls /mnt/us/opt/nmap-5.61TEST2
  • run nmap
    /mnt/us/opt/nmap-5.61TEST2/bin/nmap 127.0.0.1
  • Tips

    If you’re not familar, few usual tips. Thanks to various Kindle enthusiasts it is possible to get shell terminal directly on Kindle, so you can run nmap directly from Kindle (you can also run it through ssh – of course!). I’m talking about Kindle 3. Take a look at Amazon Liberation Project and specifically this blog post.

    Compilation

  • Download appropriate scratchbox for kindle
  • run configure
    ac_cv_linux_vers=2 ./configure --host=arm-none-linux --prefix=/mnt/us/opt/nmap-5.61TEST2 --enable-static
    --without-zenmap --with-pcap=linux --with-liblua=included --with-libpcap=internal
    make
    make install
  • that’s it
  • Sample session from initial version
