Aircrack-ng 1.6 - Complete Suite Of Tools To Assess WiFi Network Security

Aircrack-ng 1.6 – Complete Suite Of Tools To Assess WiFi Network Security

Aircrack-ng is a complete suite of tools to assess WiFi network security.
It focuses on different areas of WiFi security:

  • Monitoring: Packet capture and export of data to text files for further processing by third party tools.
  • Attacking: Replay attacks, deauthentication, fake access points and others via packet injection.
  • Testing: Checking WiFi cards and driver capabilities (capture and injection).
  • Cracking: WEP and WPA PSK (WPA 1 and 2).

All tools are command line which allows for heavy scripting. A lot of GUIs have taken advantage of this feature. It works primarily Linux but also Windows, OS X, FreeBSD, OpenBSD, NetBSD, as well as Solaris and even eComStation 2.

It’s been more than a year since the last release, and this one brings a ton of improvements.

The most noticeable change are the rate display in Airodump-ng. Previously, it went up to 54Mbit. Now, it takes into account the complexity of 802.11n/ac and calculates the maximum rate that can be achieved on the AP. Expect 802.11ax rates in the next release. We brought basic UTF-8 support for ESSID and if you ever come across WPA3 or OWE, this will be displayed correctly as well. Airodump-ng has had the ability to read PCAP files for quite some time, which can be handy to generate one of the CSV/netxml or other output formats available. However, signal levels were not displayed; this has now been fixed. A new option has been added to read the files in realtime, instead of reading all at once.

Huge improvements have been done under the hood as well. Code has been cleaned up, deduplicated (Pull Request 2010), reorganized (Pull Request 2032), which lead to a lot of fixes.

This reorganization also updated the build system, which now requires automake 1.14+. This was a problem on CentOS 7, but we provide a script to install these requirements from source to solve the issue; although automake 1.14 (and other dependencies) have been released 6+ years ago, CentOS is the only distribution that doesn’t have it, and it was decided to provide a script to install the requirements was a small price to pay to improve and simplify the build system.

Other tools received fixes as well:

  • Along with a few fixes, Airmon-ng now handles more network managers, and persistent ones; no need to run airmon-ng check kill a few times for the network managers that keep restarting.
  • Airdecap-ng can now decrypt both sides of the conversation when WDS is in use.
  • As usual, we updated WPE patches for freeradius and HostAPd.
  • Python 2 is dead as of January 1st, and now all our scripts support Python 3. If you are still running Python 2, don’t worry, they are still backward compatible.
  • Aircrack-ng contains fixes for a few crashes and other regressions, as well as improved CPU detection in some cases (-u option).

We have been working on our infrastructure and have a buildbot server with quite a few systems. If you head up to our buildbot landing page, you can see the extent of the build system: 14 systems to test build on top of AppVeyor, TravisCI, and Coverity Scan, plus one to automatically package it and upload packages to packagecloud.io. It gets triggered every time we push code to our GitHub repository and you can see the details of each build for each commit on GitHub. We have an earlier blog post where you can find some details of our CI/CD.
We are currently working on bringing Mac infrastructure as well.

We keep working on our automated tests, and a few have been added; this release also brings integration tests (16 for now) to automatically test different features of airodump-ng, aireplay-ng, airbase-ng and others.

In case you find security issues in Aircrack-ng or our domains, we recently added a security policy to explain how to report them. It is on GitHub, on our website, as well as security.txt.

Building

Requirements

  • Autoconf
  • Automake
  • Libtool
  • shtool
  • OpenSSL development package or libgcrypt development package.
  • Airmon-ng (Linux) requires ethtool.
  • On windows, cygwin has to be used and it also requires w32api package.
  • On Windows, if using clang, libiconv and libiconv-devel
  • Linux: LibNetlink 1 or 3. It can be disabled by passing –disable-libnl to configure.
  • pkg-config (pkgconf on FreeBSD)
  • FreeBSD, OpenBSD, NetBSD, Solaris and OS X with macports: gmake
  • Linux/Cygwin: make and Standard C++ Library development package (Debian: libstdc++-dev)

Optional stuff

  • If you want SSID filtering with regular expression in airodump-ng (-essid-regex) pcre development package is required.
  • If you want to use airolib-ng and ‘-r’ option in aircrack-ng, SQLite development package >= 3.3.17 (3.6.X version or better is recommended)
  • If you want to use Airpcap, the ‘developer’ directory from the CD/ISO/SDK is required.
  • In order to build besside-ng, besside-ng-crawler, easside-ng, tkiptun-ng and wesside-ng, libpcap development package is required (on Cygwin, use the Aircap SDK instead; see above)
  • For best performance on FreeBSD (50-70% more), install gcc5 (or better) via: pkg install gcc9
  • rfkill
  • If you want Airodump-ng to log GPS coordinates, gpsd is needed
  • For best performance on SMP machines, ensure the hwloc library and headers are installed. It is strongly recommended on high core count systems, it may give a serious speed boost
  • CMocka for unit testing
  • For intergation testing on Linux only: tcpdump, HostAPd, WPA Supplicant and screen

Installing required and optional dependencies
Below are instructions for installing the basic requirements to build aircrack-ng for a number of operating systems.
Note: CMocka, tcpdump, screen, HostAPd and WPA Supplicant should not be dependencies when packaging Aircrack-ng.

Linux

Debian/Ubuntu

brew install autoconf automake libtool openssl shtool pkg-config hwloc pcre sqlite3 libpcap cmocka

Windows

Cygwin
Cygwin requires the full path to the setup.exe utility, in order to automate the installation of the necessary packages. In addition, it requires the location of your installation, a path to the cached packages download location, and a mirror URL.
An example of automatically installing all the dependencies is as follows:

c:cygwinsetup-x86.exe -qnNdO -R C:/cygwin -s http://cygwin.mirror.constant.com -l C:/cygwin/var/cache/setup -P autoconf -P automake -P bison -P gcc-core -P gcc-g++ -P mingw-runtime -P mingw-binutils -P mingw-gcc-core -P mingw-gcc-g++ -P mingw-pthreads -P mingw-w32api -P libtool -P make -P python -P gettext-devel -P gettext -P intltool -P libiconv -P pkg-config -P git -P wget -P curl -P libpcre-devel -P libssl-devel -P libsqlite3-devel

MSYS2

pacman -Sy autoconf automake-wrapper libtool msys2-w32api-headers msys2-w32api-runtime gcc pkg-config git python openssl-devel openssl libopenssl msys2-runtime-devel gcc binutils make pcre-devel libsqlite-devel

Compiling
To build aircrack-ng, the Autotools build system is utilized. Autotools replaces the older method of compilation.
NOTE: If utilizing a developer version, eg: one checked out from source control, you will need to run a pre-configure script. The script to use is one of the following: autoreconf -i or env NOCONFIGURE=1 ./autogen.sh.
First, ./configure the project for building with the appropriate options specified for your environment:

./configure <options>

TIP: If the above fails, please see above about developer source control versions.
Next, compile the project (respecting if make or gmake is needed):

  • Compilation:
    make
  • Compilation on *BSD or Solaris:
    gmake

Finally, the additional targets listed below may be of use in your environment:

  • Execute all unit testing:
    make check
  • Execute all integration testing (requires root):
    make integration
  • Installing:
    make install
  • Uninstall:
    make uninstall

./configure flags
When configuring, the following flags can be used and combined to adjust the suite to your choosing:

  • with-airpcap=DIR: needed for supporting airpcap devices on windows (cygwin or msys2 only) Replace DIR above with the absolute location to the root of the extracted source code from the Airpcap CD or downloaded SDK available online. Required on Windows to build besside-ng, besside-ng-crawler, easside-ng, tkiptun-ng and wesside-ng when building experimental tools. The developer pack (Compatible with version 4.1.1 and 4.1.3) can be downloaded at https://support.riverbed.com/content/support/software/steelcentral-npm/airpcap.html
  • with-experimental: needed to compile tkiptun-ng, easside-ng, buddy-ng, buddy-ng-crawler, airventriloquist and wesside-ng. libpcap development package is also required to compile most of the tools. If not present, not all experimental tools will be built. On Cygwin, libpcap is not present and the Airpcap SDK replaces it. See –with-airpcap option above.
  • with-ext-scripts: needed to build airoscript-ng, versuck-ng, airgraph-ng and airdrop-ng. Note: Each script has its own dependencies.
  • with-gcrypt: Use libgcrypt crypto library instead of the default OpenSSL. And also use internal fast sha1 implementation (borrowed from GIT) Dependency (Debian): libgcrypt20-dev
  • with-duma: Compile with DUMA support. DUMA is a library to detect buffer overruns and under-runs. Dependencies (debian): duma
  • disable-libnl: Set-up the project to be compiled without libnl (1 or 3). Linux option only.
  • without-opt: Do not enable stack protector (on GCC 4.9 and above).
  • enable-shared: Make OSdep a shared library.
  • disable-shared: When combined with enable-static, it will statically compile Aircrack-ng.
  • with-avx512: On x86, add support for AVX512 instructions in aircrack-ng. Only use it when the current CPU supports AVX512.
  • with-static-simd=: Compile a single optimization in aircrack-ng binary. Useful when compiling statically and/or for space-constrained devices. Valid SIMD options: x86-sse2, x86-avx, x86-avx2, x86-avx512, ppc-altivec, ppc-power8, arm-neon, arm-asimd. Must be used with –enable-static –disable-shared. When using those 2 options, the default is to compile the generic optimization in the binary. –with-static-simd merely allows to choose another one.

Examples:

  • Configure and compiling:
    ./configure --with-experimental
    make
  • Compiling with gcrypt:
    ./configure --with-gcrypt
    make
  • Installing:
    make install
  • Installing (strip binaries):
    make install-strip
  • Installing, with external scripts:
    ./configure --with-experimental --with-ext-scripts
    make
    make install
  • Testing (with sqlite, experimental and pcre)
    ./configure --with-experimental
    make
    make check
  • Compiling on OS X with macports (and all options):
    ./configure --with-experimental
    gmake
  • Compiling on OS X 10.10 with XCode 7.1 and Homebrew:
    env CC=gcc-4.9 CXX=g++-4.9 ./configure
    make
    make check

    NOTE: Older XCode ships with a version of LLVM that does not support CPU feature detection; which causes the ./configure to fail. To work around this older LLVM, it is required that a different compile suite is used, such as GCC or a newer LLVM from Homebrew.
    If you wish to use OpenSSL from Homebrew, you may need to specify the location to its’ installation. To figure out where OpenSSL lives, run:
    brew --prefix openssl
    Use the output above as the DIR for --with-openssl=DIR in the ./configure line:

    env CC=gcc-4.9 CXX=g++-4.9 ./configure --with-openssl=DIR
    make
    make check
  • Compiling on FreeBSD with gcc9
    env CC=gcc9 CXX=g++9 MAKE=gmake ./configure
    gmake
  • Compiling on Cygwin with Airpcap (assuming Airpcap devpack is unpacked in Aircrack-ng directory)
    cp -vfp Airpcap_Devpack/bin/x86/airpcap.dll src
    cp -vfp Airpcap_Devpack/bin/x86/airpcap.dll src/aircrack-osdep
    cp -vfp Airpcap_Devpack/bin/x86/airpcap.dll src/aircrack-crypto
    cp -vfp Airpcap_Devpack/bin/x86/airpcap.dll src/aircrack-util
    dlltool -D Airpcap_Devpack/bin/x86/airpcap.dll -d build/airpcap.dll.def -l Airpcap_Devpack/bin/x86/libairpcap.dll.a
    autoreconf -i
    ./configure --with-experimental --with-airpcap=$(pwd)
    make
  • Compiling on DragonflyBSD with gcrypt using GCC 8
    autoreconf -i
    env CC=gcc8 CXX=g++8 MAKE=gmake ./configure --with-experimental --with-gcrypt
    gmake
  • Compiling on OpenBSD (with autoconf 2.69 and automake 1.16)
    export AUTOCONF_VERSION=2.69
    export AUTOMAKE_VERSION=1.16
    autoreconf -i
    env MAKE=gmake ./configure
    gmake
  • Compiling and debugging aircrack-ng
    export CFLAGS='-O0 -g'
    export CXXFLAGS='-O0 -g'
    ./configure
    make
    LD_LIBRARY_PATH=.libs gdb --args ./aircrack-ng [PARAMETERS]

Packaging
Automatic detection of CPU optimization is done at run time. This behavior is desirable when packaging Aircrack-ng (for a Linux or other distribution.)
Also, in some cases it may be desired to provide your own flags completely and not having the suite auto-detect a number of optimizations. To do this, add the additional flag --without-opt to the ./configure line:
./configure --without-opt

Using precompiled binaries

Linux/BSD

  • Use your package manager to download aircrack-ng
  • In most cases, they have an old version.

Windows

  • Install the appropriate “monitor” driver for your card (standard drivers doesn’t work for capturing data).
  • aircrack-ng suite is command line tools. So, you have to open a commandline Start menu -> Run... -> cmd.exe then use them
  • Run the executables without any parameters to have help
