OSfooler-NG


License: GPL v3 [Version: 1.0b Maintenance

Synopsis

This is a fork of segofensiva/OSfooler-ng.

Main reason of that fork is that original project seems to be an abandoned proof-of-concept, but the project is still valuable. By now the main difference is the change of Python2's nfqueue (NetfilterQueue) version from 0.5 to 0.8.1 for the sake of run the OSfooler-ng on different distros, not just deb-based.

Yes, it's Python2 yet. If you know how to properly move NetfilterQueue to Python 3.6+ and can test the project nicely and in short time - your help is welcome.

Original author's project presentation can be found on Youtube https://www.youtube.com/watch?v=psxxT00KavM. You may also find a few articles about OSfooler-NG. This version is a remake of 2014' OSfooler made by the same person, but the old one is archived and should be concidered lost. The whole topic of OS-fingerprinting and it's defeating is rather obscure.
OSfooler-NG is working, but not yet perfect even against nmap and p0f. Any futher help, even testcases, and so is highly needed.

By now it's been tested fine on Arch and CentOS7, CentOS8, Ubuntu 18.04.

You may help hugely by trying this on different distros and submit issues. By now it's been tested fine on Arch and CentOS7.

Installation

To get this version, just use git:

$ git clone https://github.com/moonbaseDelta/OSfooler-ng.git

You need to install python NetfilterQueue (v0.8.1 or more) linux package. Download from PyPi:

$ wget https://files.pythonhosted.org/packages/39/c4/8f73f70442aa4094b3c37876c96cddad2c3e74c058f6cd9cb017d37ffac0/NetfilterQueue-0.8.1.tar.gz
$ tar -xzf NetfilterQueue-0.8.1.tar.gz
$ cd NetfilterQueue-0.8.1
$ sudo python2 setup.py install

or try:

$ pip2 install NetfilterQueue

Install OSfooler-ng in the standard way:

$ sudo python2 setup.py install

There're also instructions for some specific distros in project's Wiki.

Known issues

No such device IO error (error code 19):

  • By default program uses 'eth0' interface that may not be even exist on your machine
  • Find your main TCP/IP interface (you can find it by 'ip a' command)
  • Run OSfooler-ng commands with:
$ <osfooler command> -i 'YOURINTERFACE'

Usage

Active Fingerprinting: nmap

To get the full list of OS to emulate, just use the flag '-n':

$ osfooler-ng -n
 [+] Please, select nmap OS to emulate
    + "2N Helios IP VoIP doorbell"
    + "2Wire BT2700HG-V ADSL modem"
    + "2Wire 1701HG wireless ADSL modem"
    [...]

    + "ZyXEL Prestige 660HW-D1 wireless ADSL router"
    + "ZyXEL ZyWALL 2 Plus firewall"

To emulate an specific OS, just use the flag '-o' with the OS you want to emulate:

$ osfooler-ng -m "Sony Ericsson W705 or W715 Walkman mobile phone"

Passive Fingerprinting: p0f v2

To get the full list of OS to emulate, just use the flag '-l':

$ osfooler-ng -p 
Please, select p0f OS Genre and Details
        OS Genre="AIX" Details="4.3"
        OS Genre="AIX" Details="4.3.2 and earlier"
        OS Genre="AIX" Details="4.3.3-5.2 (1)"

        OS Genre="-*NMAP" Details="OS detection probe w/flags (4)"
        OS Genre="-*NAST" Details="syn scan"

To emulate any p0f OS, just use the flag '-o' with the OS Genre. This will choose the main OS and custom version will be randomly loaded when a SYN packet is detected. For example:

$ osfooler-ng -o "PalmOS"
 [+] Mutating to p0f:

You can also emulate the full p0f OS, using '-' with the OS Genre and '-d' with custom details:

$ osfooler-ng -o "Windows" -d "XP bare-bone"

Active and Passive Fingerprinting: nmap & p0f

OSfooler-ng is also capable os emulating both OS to defeat nmap and p0f. Just combine the parameters above:

$ osfooler-ng -m "Microsoft Windows 2000 SP4" -o "Windows" -d "2000 SP4"

Searching for Operating Systems

You can search inside nmap/p0f database for a specific OS, instead of getting the whole list. Just use the flag '-s' and enter the keyword you want to search for (case insensitive). You'll get any match found, and if it belongs to nmap or p0f databases:

$ osfooler-ng -s playstation
 [+] Searching databases for: 'playstation'
      [nmap] "Sony Playstation 4 or FreeBSD 10.2-RELEASE"
      [nmap] "Sony PlayStation 2 game console test kit 2.2.1"
      [nmap] "Sony PlayStation 3 game console"
      [nmap] "Sony PlayStation 3 game console test kit"
      [nmap] "Sony PlayStation 2 game console"
      [p0f] OS: "Sony" DETAILS: "Playstation 2 (SOCOM?)"

Update nmap database

Use the flag '-u' to check if there's a new version of nmap's database avaiable and to download it

$ osfooler-ng -u
 [+] Checking nmap database... latest!

Custom flags

There are other interesting flags:

  • '-v': Show info about every modified packet
  • '-i ': Choose network interface (eth0 by default)
  • '-V': Show OSfooler-ng banner and current version installed
