This was announced very recently:

"Attackers can steal the victim's login credentials, therefore hijacking their virtual persona, by simply tricking them into visiting a malicious Web page"

Ok so read this article... Now, how does one go about protecting oneself from this exploit, please? What all can be done to ward this off other than the obvious of not giving your password to anyone, changing it monthly, etc? Please be specific n Thanks ;)

So, the obvious would be to use Firefox or another mozilla based browser. I just tried the exploit and got:

Firefox doesn't know how to open this address, because the protocol (secondlife) isn't associated with any program.

Even if you use IE you should be fine if you also use Vista, since it should ask you if its ok to open the secondlife client.
I can't try out what happens on Win XP, since i don't have it installed. But if you want to try out what happens in a safe enviournment, open Notepad or whatever, paste in this

From: someone

<html>
<head>
<title>Example 1</title>
<body bgcolor="#FFFFFF" text="#000000">
<iframe src='secondlife://" -autologin -loginuri "http://localhost/login.php'></iframe>
</body>
</html>


and save it as "login-exploit.html" for example.
when you try to open this newly created page with IE, it will try to open the SL client and connect to your non existant PHP server.. or maybe not. You'll have to try this out yourself. But again, its a totally safe way to try out what actually would happen.

What might try to stop this exploit is (If you decide to stick with IE):
-Adding "secondlife://" to the list of blocked sites on IE
-Not using the auto save password feature of the SL client

edit:
Grrr, the vbcode is messing with the html code i posted here, adding it stuff to it, even if i switch"automatically parse links in text" off :p
Ah, fixed ^^

How do you add secondlife:// as a blocked site to IE?

As far as I know, all you can do is add sites to block cookies.

you can use maxthon (runs the IE core) or opera to block adds and url's. i use opera as my primary browser and maxthon when i need IE compatability. maxthon is what Internet explorer should be, like IE on steroids. Opera is what they all should be.

dont start with the firefox fanboy stuff ;)
i never really liked firefox, but i think its good.

Patch for windows viewer 1.18.2.0

I didn't want to wait for an updated viewer from Linden so I produced a binary patch for the windows viewer.

I've attached it to the JIRA entry. http://jira.secondlife.com/browse/VWR-2508

This should prevent the exploit working as it disables the -loginuri feature.
