[tcpxtract] Tool for Extracting Files from Network Traffic


tcpxtract is a tool for extracting files from network traffic based on file signatures. Extracting files based on file type headers and footers (sometimes called "carving") is an age old data recovery technique. Tools like Foremost employ this technique to recover files from arbitrary data streams. Tcpxtract uses this technique specifically for the application of intercepting files transmitted across a network. Other tools that fill a similar need are driftnet and EtherPEG. driftnet and EtherPEG are tools for monitoring and extracting graphic files on a network and is commonly used by network administrators to police the internet activity of their users. The major limitations of driftnet and EtherPEG is that they only support three filetypes with no easy way of adding more. The search technique they use is also not scalable and does not search across packet boundries. tcpxtract features the following:

Supports 26 popular file formats out-of-the-box. New formats can be added by simply editing its config file.

  • With a quick conversion, you can use your old Foremost config file with tcpxtract.
  • Custom written search algorithm is lightning fast and very scalable.
  • Search algorithm searches across packet boundries for total coverage and forensic quality.
  • Uses libpcap, a popular, portable and stable library for network data capture.
  • Can be used against a live network or a tcpdump formatted capture file.

[Intercepter-ng] Sniffer de Red con SSLstrip para Android


Intercepter-NG es una aplicación que nos permitirá capturas el tráfico de datos en la red local a la que estemos conectados. Esta herramienta tiene la funcionalidad de analizador de protocolos al más puro estilo Wireshark aunque con muchísimas menos opciones. Con Intercepter-ng podremos ver cookies de las diferentes conexiones que se realicen así como realizar ataques contra SSL con SSLStrip.

En RedesZone tenéis un completo manual de utilización de SSLstrip y cómo funciona exactamente para “descifrar” el tráfico SSL. La aplicación tiene varias pestañas para elegir el objetivo, iniciar el analizador de paquetes y ver todo el tráfico en detalle y también las cookies de las páginas web que la víctima ha visitado.
Lo primero que debemos hacer con esta aplicación es pulsar en el radar para escanear los posibles objetivos, una vez seleccionado el objetivo nos movemos por las pestañas para ir viendo las diferentes opciones que nos brinda esta aplicación.

Alguna de las utilidades es que nos permite recuperar la contraseña y los archivos que se transmitan en la red que estamos analizando.

Los requisitos que necesita esta aplicación son los siguientes:
  • Android 2.3.3 o superior
  • Ser root
  • Tener instalado Busybox

[Wireshark v1.10.0 RC2] The world’s foremost network protocol analyzer

Wireshark is the world’s foremost network protocol analyzer. It lets you capture and interactively browse the traffic running on a computer network. It is the de facto (and often de jure) standard across many industries and educational institutions.

Wireshark development thrives thanks to the contributions of networking experts across the globe. It is the continuation of a project that started in 1998.

Changelog v1.10.0 RC 2

Wireshark 1.10.0rc2 has been released. Installers for Windows, OS X, and source code are now available. This is the first release candidate for Wireshark 1.10.0.

New and Updated Features
The following features are new (or have been significantly updated) since version 1.8:

  • Wireshark on 32- and 64-bit Windows supports automatic updates.
  • The packet bytes view is faster.
  • You can now display a list of resolved host names in “hosts” format within Wireshark.
  • The wireless toolbar has been updated.
  • Wireshark on Linux does a better job of detecting interface addition and removal.
  • It is now possible to compare two fields in a display filter (for example: udp.srcport != udp.dstport). The two fields must be of the same type for this to work.
  • The Windows installers ship with WinPcap 4.1.3, which supports Windows 8.
  • USB type and product name support has been improved.
  • All Bluetooth profiles and protocols are now supported.
  • Wireshark now calculates HTTP response times and presents the result in a new field in the HTTP response. Links from the request’s frame to the response’s frame and vice-versa are also added.
  • The main welcome screen and status bar now display file sizes using strict SI prefixes instead of old-style binary prefixes.
  • Capinfos now prints human-readable statistics with SI suffixes by default.
  • It is now possible to open a referenced packet (such as the matched request or response packet) in a new window.
  • Tshark can now display only the hex/ascii packet data without requiring that the packet summary and/or packet details are also displayed. If you want the old behavior, use -Px instead of just -x.
  • Wireshark can be compiled using GTK+ 3.
  • The Wireshark application icon, capture toolbar icons, and other icons have been updated.
  • Tshark’s filtering and multi-pass analysis have been reworked for consistency and in order to support dependent frame calculations during reassembly. See the man page descriptions for -2, -R, and -Y.
  • Tshark’s -G fields2 and -G fields3 options have been eliminated. The -G fields option now includes the 2 extra fields that -G fields3 previously provided, and the blurb information has been relegated to the last column since in many cases it is blank anyway.
  • Wireshark dropped the left-handed settings from the preferences. This is still configurable via the GTK settings (add “gtk-scrolled-window-placement = top-right” in the config file, which might be called /.gtkrc-2.0 or /.config/gtk-3.0/settings.ini).
  • Wireshark now ships with two global configuration files: Bluetooth, which contains coloring rules for Bluetooth and Classic, which contains the old-style coloring rules.
