Firesheep HTTP Session Hijacking Tools


Firesheep HTTP Session Hijacking Tools, nowadays maybe there’s a lot of people know about cracking (network cracking), it is a modification or disable features which are considered undesirable by the person cracking the network. Maybe for some people when they hear about cracking the network it looks like a very hard todo’s because it involved a high skill programming language or understanding networking.

What is Session Hijacking

Every time you connected to the web application (usually a dynamic web application) you will have a unique ID called "session", this session will identifies you as a valid user and will always valid until you kill the session (log out process) or the session has expired. Some bad people trying to identifies or guessing the session ID value to gain privileges as a valid user in a web application.

Firesheep HTTP Session Hijacking

Firesheep is a firefox extension to do the session hijacking. I was very surprised that this tools can hijack Facebook, Twitter, WordPress, Amazon, etc from the valid user. The most important thing that this tools is very easy to configure and to launch an attack. Just a few step :

1. Download Firesheep

2. Sit on a unencrypted wireless network

3. Turn on your wireless card(support promiscious mode, such as : atheros, orinocco, etc) and join the network

4. Start capturing with firesheep

5. Just wait until some user authenticate at the facebook, twitter, etc.

Step by Step Firesheep Configuration

1. The picture below is the interface of firesheep(click view –> sidebar –> firesheep) and you can click the red circle for preferences

2. In this picture you should choose which interface you want to capture the data. for example when you’re in a wireless network, you should activate the wireless adapter.

3. This picture below tells you which website session can hijacked handle by this addons,

4. Usually when capturing data, will use TCP port 80, because if it’s 443 I think will be encrypted, but I still didn’t try for another port :-).

5. When you finish, click the "Start Capturing" and wait until someone authenticate some website on the website list.


1. You can use Blacksheep,

2. You can tunnel your internet connection,

3. Don’t use "Remember Me" feature in public internet area(Hotspot), and logout after you finish use the internet.

4. Some people says that clear the browser cache and history may be another way, but you can read my other posts why it’s not the really good way

That’s it. I hope you can use this tutorials in a good way :-) if any question, you can contact me or drop some comment.

    bos ini cuma bisa kalo card adapternya dukung promiscuous mode aja, kalo ga dia cuma bisa baca data lokal PC kita aja, oya gmana kalo di LAN ( cable ) apa bisa ya ?

  5. argenta says:

    My wireless adapter is Realtek RTL8191SE Wireless LAN 802.11n PCI-E NIC
    does this adapter support promiscuous mode ?

    • v4L says:

      I haven’t try the realtek, but if you want to make sure your wi-fi card supported promiscious mode or not, you can try some application that needed promiscious mode for your wi-fi card, such as :
      One thing you should know that promiscious mode means that your device will receive all network traffic(even the packets not addressed to you), so when you activate or trying the tools, just check it…are there any packets captured by the application?If the application captured nothing, it’s mean that your wi-fi card doesn’t support promiscious mode. Hope it help you :-)

  6. bontet says:

    bro…salam indonesia..
    kalau wireless USB gw TL-WN722NC..
    kira2 bisa gak ya?

    • v4L says:

      harus dicoba bro…cobain beberapa program yang emang membutuhkan kemampuan wi-fi card untuk melakukan promiscious mode misalnya : wireshark, firesheep. Kalau tools tersebut dicoba dijalankan coba dilihat apa menangkap suatu paket data?kalau misalnya nggak ada, berarti kemungkinan wi-fi card nya nggak support promiscious mode :) itu yang saya tahu buat ngecek bisa/nggak nya. Tapi kalau yang pasti “Atheros sm Orinocco” itu udah pasti bisa Promiscious Mode.

  7. ijocrumut says:

  11. har says:

    I have visited porn sites from my job's pc. I deleted my history, cache, cookies, temporary files and so, but how can i know if they are stored on the main company's server, how can i delete them?

    • v4L says:

      The answer is you can’t :-) because your company server maybe already cache it and already record your IP address with website(porn) destination…if you can install any software on your PC, maybe you can tunnel your connection or use any circumventor software on the net to minimize detection from your company proxy server.
