I went to a web site the other day, and I saw a strange error message:

 

 

After that, I haven't had any other problems going to any other web site. Do you know what that message means? Was somebody doing a DOS attack against my computer, or the web site?

Looks like the message is saying it was directed at you... it could be a false alarm especially if you did not noice anything odd

 

Cheers,

Seems like somewhat of an odd message, but probably harmless.

Might have just been a javascript box set up as a joke...

If you click OK it probably takes you to a site selling penile enhancement drugs (DOS Attack? Der Ober Schlong mit Viagara! Yah!)

If your using IE I would not put it past - things like that ar easy to do in IE (CRAP). Or it could be trying to make you uy some fancy $400 firewall sofware that does nothing special...

I agree with the others. IE doesn't have the capabilities of warning of a DoS attack so it couldn't issue that warning. Plus that looks exactly like a standard javascript pop-up box.

the server that the site is stored on, however, could be configered to redirect any access attempts to 127.0.0.1 and display a javascript popup thingy if it thinks that it is being DoS'd.

Pretty pointless. If you're being DoS'd, the last thing you want to do is even allow traffic from any potential attackers, let alone give them a nice website popup.

a potential attacker would also be a potential legitimate visitor... maybe they think the popup is politer than just not answring? And if it's only being dos'd a little bit, delivering the redirect/popups would probably be a lot less strain than delivering the web pages.

 

although that's entirely speculation/guesswork on my part.

If you're being DoS'd, the entire point is that your server is being overloaded with a lot of requests. Why serve (essentially) useless requests under these circumstances? It's just going to put more strain on the server.

 

It looks like some cheap JavaScript script. I don't think it would be particularly useful in preventing any sort of DoS attack personally.

herme3 what site did you get it off? I'll visit it and find out properly rather than guessing.

I don't remember what site I got it from, I think it was supposed to be an advertising service. When I clicked OK, it went to a "The page cannot be displayed" error.

It might have really directed you to 127.0.0.1

 

On some networks this will bring up the server or host computer, but on other networks (incl. my own) it is nothing and meaningless so you would get the "page cannot be displayed" message because it [the page] doesn't exist.

I thought 192.168.0.1 is supposed to take you to the host computer and 127.0.0.1 is supposed to be a loopback to your own computer.

Both the IPs you mention do (in some cases and then only by default) do the things you say.

 

However as I said it is not always the case (depends on router/server) and is only the default values and so can be changed by the user.

I got this error yesterday, you think I should be worried?

 

 

I think it was trying to take over my computer or something. I crtl+alt+deleted internet explorer so it wouldn't close my window.

Err... I've never seen that. There's always javascript:window.close() that closes your window, but I don't think IE gives you an error message first. Perhaps they're messing with your mind.

 

Don't use IE.

 

 

edit: noticed that there's a misspelling in herme3's error box... I think it's a javascript trick.

javascript:window.close() doesn't display a popup, try typing it into the address bar in IE and press enter, it will just shut the window, no message. Actually, 1veedo, try doing that just to check you haven't got some javascript error message thing enabled.

 

And what site where you on when you got it? If it was a one off and you were browsing the internet then it's probably just a page you were on and nothing to worry about.

 

Oh yeah, good point Cap'n... herme3's error message says "furthur", MS wouldn't make that typo, someone coding a popup box could.

The DOS attack thing is likely a joke but could be your router/firewall warning you of a problem. 127.0.0.1 is your own computers internal address btw and I cant think of any reason you'd be redirected to that.

A router cannot create popup messages on a computer (unless you are on the router config page). Furthermore even if it did it would not be through IE (unless you were on the router config page in IE). But anyway, herme3 would have known if he was on his router's config page and he wasn't.

 

Also the fact that he says that 127.0.0.1 is nothing on his network makes it even less likely that the message could have originated from the router.

 

Similarly a firewall message would not come through IE.

It actually is a message programmed somewhere into IE. I've seen it before on multiple web sites. Sometimes the windows just closes, and sometimes that message is displayed. Perhaps it depends on what code is used to close the window.

I wasn't on my router's config page, so I don't think the message came from my router. I use ZoneAlarm Pro for my firewall, and all of its messages look very professional unlike the message that I got.

I second this I can't remember when it appears and doesn't though, I used to know

Sometimes a code telling a window to shut brings up a "DoS attack detected" popup, err, why?

 

Or maybe it is that you program there to be a popup box which if the user clicks OK it shuts the window, I could make that.
