About the DNS Changer virus

[Lietseu]

Good evening everyone and especially distracted ...
The DNS Changer virus should go into "service" from the 8th of this month, here is a useful link to find it on your machine ...
http://dns-ok.be/
This link contains information about this new alarm that would affect everyone ...

Christophe or someone else, can he confirm the validity of this?

I tested it at home, my bike looks clean

Meow to all and good winds!

[Christophe]

Risk bof bof .... far from the media coverage that is made (I think) ...

As for all viruses, there is a risk but only for infected machines ... barely 10 000 in France after: http://www.clubic.com/antivirus-securit ... net-8.html so it's not much ... not to say anything at all!

More technical details: http://www.levif.be/info/actualite/tech ... 511174.htm

It is therefore far from concerning "everyone" ...

I'm wary like the plague of this thing that wants to check my computer ... it's often these fake verifier who are the real instalateur of virus

when you have an antivirus that works viruses can not instaler without asking permission to the user: the trick is to send a false verification software for the user to click and accept the instalation of some thing

to deceive the enemy the instalation of the virus does not produce effects until later, so that we do not understand at first glance the problem ... we can believe that the verifier anti virus works and the advisor other

Yes but no virus literally but malware or spyware can actually happen ...

It's clean, for the French: http://dns-ok.fr

he is sure that this thing does not control anything ... he must serve something well, and I suspect the worst

[Christophe]

I think he has not understood anything about how the web works the young geek who writes this message ...

If you use a bad dns, then you are redirected to the KO page
If you use a good dns, then you are redirected to the OK page

I think a web server can detect which DNS you use ... without having to use a script ...

So in fact the test should be done after the 8 March (when the virus has acted), not before ... but there you will have more access to the web you can not do the test anymore

So yes it's a bit phony ... but if it avoids paranoia ...

there is bizare stuff on these dns server

it is an easy IP address to see in windows: for each network access your computer consults this ip address to know exactly where it should look

in general this address is in the modem router ... if this address is at the other end of the world, this other end of the world controls all your communication

A DNS makes the link between the domain names and the IPs of the physical servers. This is not your router or your box but the DNS are necessarily configured in (of course of course) ...

But you can surf without DNS provided that all hypertext links are in http: // ABCD = IP number of the site server

But it's easier to remember a name in letters than an IP in figures ...

Here are the DNS exist ...

Finally it is sure that a web server can know the DNS of the visitor ... since it is he who makes the link between the name of the domain and the machine ...

This is perhaps how statistics tools know the provider of the user ... (it's faster than an IP whois)

I complete

the dns server is easy to see in windows in a corporate network configured in fixed IP

but at home with a live box, there is no IP and dns defined: it is "obtained by DHCP" therefore automatic

it can be an explanation of the functioning of dns-ok.be which gives the page OK or bad only according to your IP address

the ip address given automatically to each connection can be clearly identifiable as clean or passing by or it is not necessary

the defect sought is not in the computer but in the box or even further

that is why in case of default dns-ok does not solve the problem itself but asks to contact the operator

[Christophe]

but at home with a live box, there is no IP and dns defined: it is "obtained by DHCP" therefore automatic

DHCP = tool that provides the addresses of your local network.
Your DHCP = the box

If you want to know your DNS, it is necessarily in the box, you hit the local ip of your box http: // ipdetabox (see manual for details of config ...)

it can be an explanation of the functioning of dns-ok.be which gives the page OK or bad only according to your IP address

No, a remote site does have access to your "internet" IP and most likely to your provider's DNS ...
