DNS poisoning method commonly used by hackers

DNS poisoning is a method by which hackers took control impression that certain sites known or not.
DNS is the protocol that makes lagatura between the domain name and IP address for any website in the world that has one or more IP addresses.
When we type "google.com" in our browser, our computer has three options for finding the address or IP addresses for "google.com".
1.Prima option-hosts file in C :/ windows / system32 / drivers / etc / hosts
2. The second option - private DNS (server, router)
3. The third option - Public DNS servers (OpenDNS, Google DNS)
No matter where you find the IP address for "google.com", our computer stops and no longer consults the other options. For example, if it finds the IP address for "google.com" in the hosts file, it no longer goes to the private or public DNS to confirm the validity of this address.
Thus we can to fool PC, we can tell him anything, he will believe anything found in the hosts file.
Careful.
These are safety tips designed to help in prevention, do not use the information in this tutorial malicious purposes.

  • Hello, Cristi!
    GREAT TOOLS: I also want a continuation with the tutorial about Tronsmart MK908, namely about how it behaves in the case of 1080p (even 720p) mkv files. And I do not mean the films of 1 -2 gb, as they are "offered" on the net, but the normal ones of 4,37 - 8 gb, etc. Also, I am VERY interested in running the XBMC on Android Boxes on the market, given that hardware acceleration is needed. Many android box sticks and minipcs are announced on their official pages that they would have "pre-installed" the XBMC, that it breaks, that it plays with large mkvs and in reality you only watch avi or divx because "not too lead the hardware acceleration brilliantly ". I know that XBMC Frodo android versions have appeared or I know what, dedicated to android platforms and without much need for hardware resources. I think such a tutorial would be useful, especially for those who use this platform.
    Thank you.

  • So it was with Google some time ago if I'm not mistaken this year. When we enter Google, that page appears with the wonder of the TV and a message. It was like some Arab or Moroccan hackers.

  • yes sir well see in the windows host file you say, but how you say Linux or other OS freee
    In my opinion that comes free has disadvantages for that to mean if you realize (and with your help we'll give) as the PC changed something and usually something important (as in this case) and do complaint
    software with because we changed in our pc.atunci malicious people there tell us what you want fries free Domain is not what you want.
    all respect for Linux and other free systems no offense but who made them more concrete meaning
    in case something goes awry whom we weep?
    I had a hunch about something eg download a pirated windows and May and install
    and of course it comes ,, no ,, prearranged antivirus mother does not find anything.
    that's why it's good that fired a warning
    thank Cristi

  • MisuCristi, we can protect the file read-only function activated hotst.

    He is protected if you noticed I edited with admin rights. Unfortunately all Windows users are admins and grant rights to all applications, regardless of their origin.

    Any system has a file hosts, including Linux distributions, including Android.

  • If you had tested the application, don't "sting" me anymore. remove and add others [I for example added RO - RCS-RDS 193.231.236.25
    193.231.236.30] you can even test these DNS [benchmark] also supports IPv6, you can choose which adapter to change its DNS [you can change it to all adapters or only one]. etc. The ones from Softpedia give it 5 stars out of 5. Test it, it has 520 Kb and it is portable, you can use it.

  • DOES IT LOOK LIKE I HAVE TO WORRY? everything is fine? # BitDefender has clean hosts file

    127.0.0.1 localhost
