Wireshark, stealing passwords on free wi-fi networks

Today we're doing something special, we will try to intercept your login browser using a software called Wireshark extraordinary.
I'll show you how easily you can lose the password and username if you use when you log on public wifi networks.
These networks are the preferred target of hackers, they capture all traffic from that network after you login decode and extract data from Facebook, Twitter, and data from credit cards and more.
This tutorial is meant to make you pay attention to potential hazards that you may encounter when using an unsecured wi-fi network.
A simple walk through the old center in Bucharest, find dozens of hotspots, cafes and restaurants make most of free Wi-Fi. Unfortunately those networks are not configured properly and do more harm than good customer.
The free wi-fi networks:
1. Do not make online payments.
2. No login on facebook, twitter, gmail, yahoo, etc..
3. No discussion Putra private messenger or skype
4. Don't do compromising searches (you know)
5. Do not charge nothing of what you could do worse, if it gets public.
Be aware that antivirus will not do anything in this situation.

    Cristi welcome
    can monitor network traffic or whatever and from another pc?
    for showing us the PC that have not installed softu?

  2. You could go further with the tutorial, show us other tricks…
    Believe me, as a tutorial that anyone not bored!

    Please know that I can only SRI (newer baccalaureate) or State organs
    and they do not somehow?
    Does provaiderii net and they do so?
    and if they do not disclose personal data to you?
    is an interesting topic and very complex.

    CostelinaHi Cristi can monitor network traffic or whatever and from another pc? for showing us the PC that have not installed softu?

    It looks like you do not understand anything in the tutorial.
    To make it easier: Go to a McDonald's, take a laptop with Wireshark installed and start scanning the traffic of those around you. So that means you can scan other people's traffic using that McDonald's WiFi.

      Adi, this tutorial is interesting but…. without categorically contradicting you, don't be upset…
      I would never use this software. Argument: It's much too simple. Something makes me believe that if I floated something like this (with nasty intentions or simply out of curiosity), I would only succeed in losing some very important data myself. What the hell… So anyone who sees this tutorial and uses this software woke up overnight… hacker? Are you serious?
      If you want to use a software out of curiosity but you have no idea what might happen to you and if you insist, at some point you will wonder how you lost your bank or bank account when you were " the muther fucker of hacking ”. Hum….

  5. FaqTak: You could go on with the tutorial, you look to us and other tricks ... Believe me, as a tutorial that anyone not bored!

    We do not want to go in details, it was just a demo for those using public networks.
    The world must know what can happen.

  6. if you are already logged into yahoo, facebook etc. I can see the passwords. I mean I do not write them on the phone because they are already stored in your phone's browser

  7. stefan: If you are already logged into yahoo, facebook etc. I can see the passwords. I mean I do not write them on the phone because they are already stored in your phone's browser

    You type in the browser for you is the same thing.

    Hello, I have a question if you can.
    You put on an ipod 4g Wireshark? and see the traffic on it? meaning you do not necessarily have a laptop.

  11. Cristi, you said earlier that you are continuing the tutorial "how to buy on ebay"… about how to bid ... but I see that you haven't done it before. Are there any chances to see it again or not?

  12. Cristi if I wire net can someone use my netu or ip.
    I mean hacker vrun

  13. Adrian Gudus: Stay videotutorial.ro watching. Tomorrow I'll post a tutorial that will protect us in this situation, several methods ...

    Good news

  14. Sorin Chiran said

    eNdCristi if anyone Firpo net I use my netu or ip. I mean hacker vrun

    Yes methods are many, such as:
    PC-infection and the addition of a botnet or zombie network.
    -Opening a backdoor in your PC.
    -If you're using Armitage exploit the network attacker.
    And there are others but if you're careful on what you click and you have a pc as secure as you have nothing worry.

  15. Radu12 said

    Congratulations Cristi tutorial! Very very useful.
    Adrian Gudus, following tutorial wait today.

  16. Superb tutorial… and I believe that on public networks you can do more nonsense that you are, to some extent, anonymous.
    Is there a possibility in which all the data coming out of the pc on the net, to be encrypted? I'm interested in this because I use the internet on a campus… and I'm sure there are malicious people on the network. Thank you!

  17. Very useful tutorial. Mss.
    Cristi, I would very much ask you to do a tutorial based on Blue Screen at windows 8 and how we can get rid of it…. I have a rather old video card and when I install the driver after the restart I get a Blue Screen: |. On windows 7 it doesn't cause me any problems.

  18. If I use a VPN connection problems.

  19. I tried on my network secure wpa wireles 2 and show no password or user even if the network does not know even see nimik

  20. Sorin ChiranYes there are many methods such as PC-infection and the addition of a botnet or zombie network. -Opening a backdoor in your PC. -If you're using Armitage exploit the network attacker. And there are others but if you're careful on what you click and you have a pc as secure as you have nothing worry.

    "Opening a backdoor on your PC" - that's a bit difficult. most antiviruses smell backdoor and you don't care about ip theft
    "Use of the armitage exploit" - armitage is not an exploit. is a gui interface of the metasploit. with the help of armitage you escape typing in the metasploit terminal of commands.

  21. Super Useful tutorial, now if you can and counter measures!

  22. Ph YzZo said

    Congratulations tutorial! To see the passwords entered on the applications installed on your computer (like messenger, skype, etc.) that must filter? go all the http?

  23. If the protocol is HTTPS, not HTTP, you can not steal that easy. I do know that Facebook has already passed on HTTPS, I checked Yahoo.
    But in any case, 95% of websites do not use HTTPS and can steal passwords 2 taps and some users unaware that Mc bonus menu. Because yes, you can do packet sniffing and Android for example. You only need a phone with some extra-tools root well prepared. And donkeys can be bigger than a simple packet sniffing. Injections javascript, traffic redirection, etc. replacement content.
    Wi-Fi networks without password are more dangerous even than this video shows, as long as it's done by someone who knows the area.

  24. Useful and fun tutorial don'ts

  25. Sorin Chiran said

    adi"Opening a backdoor in your PC" - it's kind of hard. antivirusurile most of you do not smell backdoor and IP theft ... "use exploit Armitage" - Armitage is not an exploit. is a GUI interface to Metasploit community. with Armitage Metasploit rid of typing commands in terminal.

    True what you say and do not say it is not so, but I do not know what level of knowledge in IT has it and I tried to explain as his language (how to understand anyone) how someone malicious (many associated with hackers ) a few ways you can use PC's.

  26. Iron Maiden said

    Yes, Facebook, Yahoo and others use https, so it is valid only for http.

  27. it's not really that… I tried and at least it doesn't give you the password in your mouth, it coded them

    Cristian CismaruLe typing your browser, that's all.

  28. let me know… about what percentage is the danger that keeps me if I enter facebook from the terrace in the corner of the block? is it full of hackers everywhere ?? :))

  29. Matthew said

    wayne: Give me a break ... how much percent is the danger that if I get on facebook pasta from the upper terrace of the building? it's full of hackers everywhere? )

    rest assured that no one is wasting time finding out passwords to people. and if he found out my password what? I have no more secrets…. whoever has secrets knows what to do. the tutorial is just a small example of what can happen. no one stays at the panda to find out passwords to strangers.

  30. if you login with https can be intercepted? and if you log on the messenger application I know that can not be picked for the connection is secure and encrypted output directly to servaru yahoo (that use a secure connection whether or not the application fell yahoo). Correct me if I'm wrong crystals or adrian do not want to mislead people.

  31. you could do a tutorial on how we capture all packets den that is the local network that are connected?

  32. Post a variable way in which usually take the form data in php because this post was written, there is no post findca

  33. adrianz said

    Thank ptr Cristi tips! You're doing great!

    Iron Maiden: Ttps

    ok ms, I tried to see if something appeared on my mess but nothing… 😀

    help me please I boot the laptop to me in 10-12 secunte, please

  38. I have a problem. on my wireless network intruders and I still have to learn anything you'd like to find some messenger passwords, facebook, etc. and then tell them where took the net and that should not be missed century. The problem is that if I start smoking ami sign appears and the message The capture session Could not be Initiated (failed to set hardware filter to promiscuous mode).
    Please check that “\ Device \ NPF_ {CBA0FD46-EBDA-4FB1-AD5F-1406293A01D2}” is the proper interface.

    Hello Cristi I have a little problem on water capture and give me a login account on the phone but does not register the password on the phone on wifi only on the computer! what the problem might be from the list of network all EEU only one there I should I have and something else!

  40. George chicuHi Cristi I have a little problem on water capture and give me a login account on the phone but does not register the password on the phone on wifi only on the computer! what the problem might be from the list of network all EEU only one there I should I have and something else!

    I have shown just how you need to understand the dangers, I can not show more.
    Can I just say that with a few small changes can intercept anything. No need to know is some networking.
    You must also understand that we cannot turn this site into a "how to hack" platform. It is neither fair nor healthy.

  41. With Wireshark I can see user / pass, typed with a virtual keyboard in Windows or kaspesky?

  42. UP!

  43. Security is something pretty important to me, I insist
    UP

  44. UP

  45. Good. I found it very interesting movie. Now I work in college all with wireshark and I'd love to see a movie like this with simple commands like incremental traffic capturaraea existing PC connection, the router's MAC address determination etc.

  46. Hello, can you a tutorial on commeview, it would be great if you can watch this .. Will gladly ..
    Thank you..

  47. I 2 WiFi adapter: D-Link DWA is 1 140 and 2 is a Ralink chipset antenna 3070
    The problem is that when go with d-link, wireshark looks only my packages and not others users
    But when I bring Ralink ami says: The capture session Could not be Initiated (failed to set hardware filter to promiscuous mode).
    Please check that “\ Device \ NPF_ {F2401757-0787-4FB5-BC3C-B2F7C33CB03E}” is the proper interface.

    Hello, I have a question and I know that I can email details of running on https why do I need? Date and increasingly runs on http've managed to find. I need Linux or https necessarily to go gently on Windows? Mention that use Windows when it

  51. What to do to protect us?

  52. Mihai-Daniel said

    A question! By downloading the application from the android is possible to access all or part of the wifi network? Because when a download is even notice that says that the application can access wifi or applications accounts. There is risk here even if the network is secure?

  53. Cristi, what to look for on facebook? I want to test to see how much I expose myself when I go to PUBs…

  54. I always have fun with your "tutorials". If you really understand what you are presenting (although it doesn't seem so after the non-engineering expression), don't fool uninformed people anymore. If you still want to drive traffic to the site and earn some money from it, at least present a complete thing, to the end, without fooling the world. Even if it requires more work.
    What you did here I did in college in 2005. Not wirelessly but wired… but I still got there.
    It seemed fair to me to tell the little "hacker-wannabe" that you saw your username and password because you logged in to a site that does not offer a secure method of authentication (login). The same thing does not happen when you log on to a mail server, in an internet banking, etc. . Tell them in addition what is the difference between http and https, log on to softpedia and then on facebook… to see the difference between the boys.

  55. And I thought this was only happening in American movies 🙂 Good to know, not that I have something to hide, but not to get me either facebook or E-mail and start threatening or offending someone
